.SH WHAT IS SISU?

.SH INTRODUCTION - WHAT IS SISU?

.BR

.B SiSU
is a lightweight markup based document creation and publishing framework that
is controlled from the command line. Prepare documents for
.B SiSU
using your text editor of choice, then use
.B SiSU
to generate various output document formats.

.BR
From a single lightly prepared document (plain-text
.I UTF-8
) sisu custom builds several standard output formats which share a common (text
object) numbering system for citation of content within a document (that also
has implications for search). The sisu engine works with an abstraction of the
document's structure and content from which it is possible to generate
different forms of representation of the document.
.B SiSU
produces: plain-text,
.I HTML,
.I XHTML,
.I XML,
.I EPUB,
.I ODF:
.I ODT
(Opendocument),
.I LaTeX,
.I PDF,
and populates an
.I SQL
database (
.I PostgreSQL
or
.I SQLite
) with text objects, roughly, paragraph sized chunks so that document searches
are done at this level of granularity.

.BR
Outputs share a common citation numbering system, associated with text objects
and any semantic meta-data provided about the document.

.BR

.B SiSU
also provides concordance files, document content certificates and manifests of
generated output. Book indexes may be made.

.BR
Some document markup samples are provided in the package sisu -markup-samples.

.SH COMMANDS SUMMARY

.SH DESCRIPTION

.BR

.B SiSU
is a document publishing system, that from a simple single marked-up document,
produces multiple output formats including:
.I plaintext,
.I HTML,
.I XHTML,
.I XML,
.I EPUB,
.I ODT
(
.I OpenDocument
(
.I ODF
) text),
.I LaTeX,
.I PDF,
info, and
.I SQL
(
.I PostgreSQL
and
.I SQLite
) , which share text object numbers ("object citation numbering") and the same
document structure information. For more see: <https://sisudoc.org> or
<https://www.jus.uio.no/sisu>

.SH SISU MANUAL


.BR
The most up to date information on sisu should be contained in the sisu_manual,
available at:

.BR
  <https://sisudoc.org/sisu/sisu_manual/>

.BR
The manual can be generated from source, found respectively, either within the
.B SiSU
tarball or installed locally at:

.BR
  ./data/doc/sisu/markup-samples/sisu_manual

.BR
  /usr/share/doc/sisu/markup-samples/sisu_manual

.BR
move to the respective directory and type e.g.:

.BR
  sisu sisu_manual.ssm
.SH SISU MAN PAGES


.BR
If
.B SiSU
is installed on your system usual man commands should be available, try:

.BR
  man sisu

.BR
Most
.B SiSU
man pages are generated directly from sisu documents that are used to prepare
the sisu manual, the sources files for which are located within the
.B SiSU
tarball at:

.BR
  ./data/doc/sisu/markup-samples/sisu_manual

.BR
Once installed, directory equivalent to:

.SH INTRODUCTION TO SISU MARKUP[^3]

.SH SUMMARY

.BR

.B SiSU
source documents are
.I plaintext
(
.I UTF-8
)[^4] files

.BR
All paragraphs are separated by an empty line.

.BR
Markup is comprised of:

.BR
- at the top of a document, the document header made up of semantic meta-data
about the document and if desired additional processing instructions (such an
instruction to automatically number headings from a particular level down)

.BR
- followed by the prepared substantive text of which the most important single
characteristic is the markup of different heading levels, which define the
primary outline of the document structure. Markup of substantive text includes:

.BR
  * heading levels defines document structure

.BR
  * text basic attributes, italics, bold etc.

.BR
  * grouped text (objects), which are to be treated differently, such as code
  blocks or poems.

.BR
  * footnotes/endnotes

.BR
  * linked text and images

.BR
  * paragraph actions, such as indent, bulleted, numbered-lists, etc.
.SH MARKUP RULES, DOCUMENT STRUCTURE AND METADATA REQUIREMENTS


.BR
minimal content/structure requirement:

.BR
[metadata]
.nf
A~ (level A [title])

1~ (at least one level 1 [segment/(chapter)])
.fi


.BR
structure rules (document heirarchy, heading levels):

.BR
there are two sets of heading levels ABCD (title & parts if any) and 123
(segment & subsegments if any)

.BR
sisu has the fllowing levels:
.nf
A~ [title]              .
   required (== 1)   followed by B~ or 1~
B~ [part]               *
   followed by C~ or 1~
C~ [subpart]            *
   followed by D~ or 1~
D~ [subsubpart]         *
   followed by 1~
1~ [segment (chapter)]  +
   required (>= 1)   followed by text or 2~
text                    *
   followed by more text or 1~, 2~
   or relevant part *()
2~ [subsegment]         *
   followed by text or 3~
text                    *
   followed by more text or 1~, 2~ or 3~
   or relevant part, see *()
3~ [subsubsegment]      *
   followed by text
text                    *
   followed by more text or 1~, 2~ or 3~ or relevant part, see *()

*(B~ if none other used;
  if C~ is last used: C~ or B~;
  if D~ is used: D~, C~ or B~)
.fi

.nf
- level A~ is the tile and is mandatory
- there can only be one level A~

- heading levels BCD, are optional and there may be several of each
  (where all three are used corresponding to e.g. Book Part Section)
  * sublevels that are used must follow each other sequentially
    (alphabetically),
- heading levels A~ B~ C~ D~ are followed by other heading levels rather
  than substantive text
  which may be the subsequent sequential (alphabetic) heading part level
  or a heading (segment) level 1~
- there must be at least one heading (segment) level 1~
  (the level on which the text is segmented, in a book would correspond
  to the Chapter level)
- additional heading levels 1~ 2~ 3~ are optional and there may be several
  of each
- heading levels 1~ 2~ 3~ are followed by text (which may be followed by
  the same heading level)
  and/or the next lower numeric heading level (followed by text)
  or indeed return to the relevant part level
  (as a corollary to the rules above substantive text/ content
  must be preceded by a level 1~ (2~ or 3~) heading)

.SH MARKUP OF HEADERS

.BR
Headers contain either: semantic meta-data about a document, which can be used
by any output module of the program, or; processing instructions.

.BR
Note: the first line of a document may include information on the markup
version used in the form of a comment. Comments are a percentage mark at the
start of a paragraph (and as the first character in a line of text) followed by
a space and the comment:
.nf
% this would be a comment

.SH AVAILABLE HEADERS


.BR
Header tags appear at the beginning of a document and provide meta information
on the document (such as the
.I Dublin Core
) , or information as to how the document as a whole is to be processed. All
header instructions take the form @headername: or on the next line and indented
by once space :subheadername: All
.I Dublin Core
meta tags are available

.BR

.B @identifier:
information or instructions

.BR
where the "identifier" is a tag recognised by the program, and the
"information" or "instructions" belong to the tag/identifier specified

.BR
Note: a header where used should only be used once; all headers apart from
@title: are optional; the @structure: header is used to describe document
structure, and can be useful to know.

.SH MARKUP OF SUBSTANTIVE TEXT

.SH HEADING LEVELS


.BR
Heading levels are :A~ ,:B~ ,:C~ ,1~ ,2~ ,3~ ... :A - :C being part / section
headings, followed by other heading levels, and 1 -6 being headings followed by
substantive text or sub-headings. :A~ usually the title :A~? conditional level
1 heading (used where a stand-alone document may be imported into another)

.BR

.B :A~ [heading text]
Top level heading [this usually has similar content to the title @title: ]
NOTE: the heading levels described here are in 0.38 notation, see heading

.BR

.B :B~ [heading text]
Second level heading [this is a heading level divider]

.BR

.B :C~ [heading text]
Third level heading [this is a heading level divider]

.BR

.B 1~ [heading text]
Top level heading preceding substantive text of document or sub-heading 2, the
heading level that would normally be marked 1. or 2. or 3. etc. in a document,
and the level on which sisu by default would break html output into named
segments, names are provided automatically if none are given (a number),
otherwise takes the form 1~my_filename_for_this_segment

.BR

.B 2~ [heading text]
Second level heading preceding substantive text of document or sub-heading 3 ,
the heading level that would normally be marked 1.1 or 1.2 or 1.3 or 2.1 etc.
in a document.

.BR

.B 3~ [heading text]
Third level heading preceding substantive text of document, that would normally
be marked 1.1.1 or 1.1.2 or 1.2.1 or 2.1.1 etc. in a document
.nf
1~filename level 1 heading,

% the primary division such as Chapter that is followed by substantive text, and may be further subdivided (this is the level on which by default html segments are made)

.SH FOOTNOTES / ENDNOTES


.BR
Footnotes and endnotes are marked up at the location where they would be
indicated within a text. They are automatically numbered. The output type
determines whether footnotes or endnotes will be produced

.BR

.B markup example:
.nf
~{ a footnote or endnote }~
.fi


.BR

.B resulting output:

.BR
[^5]

.BR

.B markup example:
.nf
normal text~{ self contained endnote marker & endnote in one }~ continues
.fi


.BR

.B resulting output:

.BR
normal text[^6] continues

.BR

.B markup example:
.nf
normal text ~{* unnumbered asterisk footnote/endnote, insert multiple asterisks if required }~ continues

normal text ~{** another unnumbered asterisk footnote/endnote }~ continues
.fi


.BR

.B resulting output:

.BR
normal text [^*] continues

.BR
normal text [^**] continues

.B markup example:
.nf
normal text ~[* editors notes, numbered asterisk footnote/endnote series ]~ continues

normal text ~[+ editors notes, numbered plus symbol footnote/endnote series ]~ continues
.fi


.BR

.B resulting output:

.BR
normal text [^+2] continues

.BR

.B Alternative endnote pair notation for footnotes/endnotes:
.nf
% note the endnote marker "~^"

normal text~^ continues

^~ endnote text following the paragraph in which the marker occurs
.fi


.BR
the standard and pair notation cannot be mixed in the same document
.SH LINKS

.SH NAKED URLS WITHIN TEXT, DEALING WITH URLS


.BR
urls found within text are marked up automatically. A url within text is
automatically hyperlinked to itself and by default decorated with angled
braces, unless they are contained within a code block (in which case they are
passed as normal text), or escaped by a preceding underscore (in which case the
decoration is omitted).

.BR

.B markup example:
.nf
normal text https://www.sisudoc.org/ continues
.fi


.BR

.B resulting output:

.BR
normal text <https://www.sisudoc.org/> continues

.BR
An escaped url without decoration

.BR

.B markup example:
.nf
normal text _https://www.sisudoc.org/ continues

.fi


.BR

.B resulting output:

.BR
normal text <_https://www.sisudoc.org/> continues


.BR
where a code block is used there is neither decoration nor hyperlinking, code
blocks are discussed later in this document

.BR

.B resulting output:
.nf

.SH LINKING TEXT


.BR
To link text or an image to a url the markup is as follows

.BR

.B markup example:
.nf
about { SiSU }https://url.org markup
.fi


.BR

.B resulting output:

.BR
aboutSiSU <https://www.sisudoc.org/> markup

.BR
A shortcut notation is available so the url link may also be provided
automatically as a footnote

.BR

.B markup example:
.nf
about {~^ SiSU }https://url.org markup
.fi


.BR

.B resulting output:

.BR
aboutSiSU <https://www.sisudoc.org/> [^7] markup

.BR
Internal document links to a tagged location, including an ocn

.BR

.B markup example:
.nf
about { text links }#link_text

.B linked url footnote shortcut
.nf
{~^ [text to link] }https://url.org

% maps to: { [text to link] }https://url.org ~{ https://url.org }~

% which produces hyper-linked text within a document/paragraph, with an endnote providing the url for the text location used in the hyperlink
.fi

.nf
text marker *~name
.fi


.BR
note at a heading level the same is automatically achieved by providing names
to headings 1, 2 and 3 i.e. 2~[name] and 3~[name] or in the case of
auto-heading numbering, without further intervention.

.SH GROUPED TEXT / BLOCKED TEXT


.BR
There are two markup syntaxes for blocked text, using curly braces or using
tics
.SH BLOCKED TEXT CURLY BRACE SYNTAX


.BR
at the start of a line on its own use name of block type with an opening curly
brace, follow with the content of the block, and close with a closing curly
brace and the name of the block type, e.g.
.nf
code{

this is a code block

}code
.fi

.nf

poem{

this here is a poem

}poem
.fi

.SH BLOCKED TEXT TIC SYNTAX

.nf
``` code
this is a code block

```

``` poem
this here is a poem

```
.fi


.BR
start a line with three backtics, a space followed by the name of the name of
block type, follow with the content of the block, and close with three back
ticks on a line of their own, e.g.
.SH TABLES


.BR
Tables may be prepared in two either of two forms

.BR

.B markup example:
.nf
table{ c3; 40; 30; 30;

This is a table
this would become column two of row one
column three of row one is here

And here begins another row
column two of row two
column three of row two, and so on

}table
.fi


.BR

.B resulting output:
This is a table|this would become column two of row one|column three of row one is here』And here begins another row|column two of row two|column three of row two, and so on』


.BR
a second form may be easier to work with in cases where there is not much
information in each column

.SH CODE


.BR
Code tags code{ ... }code (used as with other group tags described above) are
used to escape regular sisu markup, and have been used extensively within this

used in the same way as group or poem tags.

.BR
A code-block is treated as an object and given a single object number. [an

with a space before and a space or newline after them
may be used.
.nf

but is depreciated).

.BR
To draw a dividing line dividing paragraphs, see the section on page breaks.
.SH PAGE BREAKS

Page breaks are only relevant and honored in some output formats. A page break
or a new page may be inserted manually using the following markup on a line on
its own:

.BR
page new =\e= breaks the page, starts a new page.

.SH BIBLIOGRAPHY / REFERENCES


.BR
There are three ways to prepare a bibliography using sisu (which are mutually
exclusive): (i) manually preparing and marking up as regular text in sisu a
list of references, this is treated as a regular document segment (and placed
before endnotes if any); (ii) preparing a bibliography, marking a heading level
1~!biblio (note the exclamation mark) and preparing a bibliography using
various metadata tags including for author: title: year: a list of which is
provided below, or; (iii) as an assistance in preparing a bibliography, marking
a heading level 1~!biblio and tagging citations within footnotes for inclusion,
identifying citations and having a parser attempt to extract them and build a
bibliography of the citations provided.

.BR
For the heading/section sequence: endnotes, bibliography then book index to
occur, the name biblio or bibliography must be given to the bibliography
section, like so:
.nf
1~!biblio~ [Note: heading marker::required title missing]
.fi

.SH A MARKUP TAGGED METADATA BIBLIOGRAPHY SECTION


.BR
Here instead of writing your full citations directly in footnotes, each time
you have new material to cite, you add it to your bibliography section (if it
has not been added yet) providing the information you need against an available
list of tags (provided below).

.BR
The required tags are au: ti: and year: [^10] an short quick example might be
as follows:
.nf
1~!biblio~ [Note: heading marker::required title missing]

au: von Hippel, E.
ti: Perspective: User Toolkits for Innovation
lng: (language)
jo: Journal of Product Innovation Management
vo: 18

note: made up to provide an example of author markup for an article with two authors
sn: Quixote & Panza, /{Taming Windmills}/ (1605)
id: quixote1605
.fi


.BR
Note that the section name !biblio (or !bibliography) is required for the
bibliography to be treated specially as such, and placed after the
auto-generated endnote section.

.BR
Using this method, work goes into preparing the bibliography, the tags author
or editor, year and title are required and will be used to sort the
bibliography that is placed under the Bibliography section

.BR
The metadata tags may include shortname (sn:) and id, if provided, which are
used for substitution within text. Every time the given id is found within the
text it will be replaced by the given short title of the work (it is for this
reason the short title has sisu markup to italicize the title), it should work
with any page numbers to be added, the short title should be one that can
easily be used to look up the full description in the bibliography.
.nf
The following footnote~{ quixote1605, pp 1000 - 1001, also Benkler2006 p 1. }~
.fi


.BR
would be presented as:

.BR

    (used in substitutions: when an id is found within text
    the short name will be used to replace it)
.fi

.SH TAGGING CITATIONS FOR INCLUSION IN THE BIBLIOGRAPHY


.BR
Here whenever you make a citation that you wish be included in the
bibliography, you tag the citation as such using special delimiters (which are
subsequently removed from the final text produced by sisu)

.BR
Here you would write something like the following, either in regular text or a
footnote
.nf
See .: Quixote, Don; Panza, Sancho /{Taming Windmills, Keeping True}/ (1605) :.
.fi


.BR

.B SiSU
will parse for a number of patterns within the delimiters to try make out the
authors, title, date etc. and from that create a Bibliography. This is more
limited than the previously described method of preparing a tagged
bibliography, and using an id within text to identify the work, which also
lends itself to greater consistency.
.SH GLOSSARY


.BR
Using the section name 1~!glossary results in the Glossary being treated
specially as such, and placed after the auto-generated endnote section (before
the bibliography/list of references if there is one).

.BR
The Glossary is ordinary text marked up in a manner deemed suitable for that
purpose. e.g. with the term in bold, possibly with a hanging indent.
.nf
1~!glossary~ [Note: heading marker::required title missing]

_0_1 *{GPL}* An abbreviation that stands for "General Purpose License." ...

_0_1 [provide your list of terms and definitions]
.fi


.BR
In the given example the first line is not indented subsequent lines are by one
level, and the term to be defined is in bold text.
.SH BOOK INDEX


.BR
To make an index append to paragraph the book index term relates to it, using
an equal sign and curly braces.

.BR
Currently two levels are provided, a main term and if needed a sub-term.
Sub-terms are separated from the main term by a colon.
.nf
  Paragraph containing main term and sub-term.
  ={Main term:sub-term}
.fi


.BR
The index syntax starts on a new line, but there should not be an empty line
between paragraph and index markup.

.BR
The structure of the resulting index would be:
.nf
  Main term, 1
    sub-term, 1
.fi


.BR
Several terms may relate to a paragraph, they are separated by a semicolon. If
the term refers to more than one paragraph, indicate the number of paragraphs.
.nf
  Paragraph containing main term, second term and sub-term.
  ={first term; second term: sub-term}
.fi


.BR
The structure of the resulting index would be:
.nf
  First term, 1,
  Second term, 1,
    sub-term, 1
.fi


.BR
If multiple sub-terms appear under one paragraph, they are separated under the
main term heading from each other by a pipe symbol.
.nf
  Paragraph containing main term, second term and sub-term.
  ={Main term:
      sub-term+2|second sub-term;
    Another term
   }

  A paragraph that continues discussion of the first sub-term
.fi


.BR
The plus one in the example provided indicates the first sub-term spans one
additional paragraph. The logical structure of the resulting index would be:
.nf
  Main term, 1,
    sub-term, 1-3,
    second sub-term, 1,
  Another term, 1
.fi

.SH COMPOSITE DOCUMENTS MARKUP


.BR
It is possible to build a document by creating a master document that requires
other documents. The documents required may be complete documents that could be
generated independently, or they could be markup snippets, prepared so as to be
easily available to be placed within another text. If the calling document is a
master document (built from other documents), it should be named with the
suffix
.B .ssm
Within this document you would provide information on the other documents that
should be included within the text. These may be other documents that would be
processed in a regular way, or markup bits prepared only for inclusion within a
master document
.B .sst
regular markup file, or
.B .ssi
(insert/information) A secondary file of the composite document is built prior
to processing with the same prefix and the suffix
.B ._sst

.BR
basic markup for importing a document into a master document
.nf
<< filename1.sst

<< filename2.ssi
.fi


.BR
The form described above should be relied on. Within the
.I Vim
editor it results in the text thus linked becoming hyperlinked to the document
it is calling in which is convenient for editing.
.SH SUBSTITUTIONS


.BR

.B markup example:
.nf
The current Debian is ${debian_stable} the next debian will be ${debian_testing}

Configure substitution in _sisu/sisu_document_make

make:
  substitute: /${debian_stable}/,'*{Wheezy}*' /${debian_testing}/,'*{Jessie}*'
.fi


.BR

.B resulting output:

.BR
The current
.B Debian
is
.B Jessie
the next debian will be
.B Stretch

.BR
Configure substitution in _sisu/sisu_document_make
.SH SISU FILETYPES


.BR

.B SiSU
has
.I plaintext
and binary filetypes, and can process either type of document.
.SH .SST .SSM .SSI MARKED UP PLAIN TEXT

.TP
.B SiSU
documents are prepared as plain-text (utf-8) files with
.B SiSU
markup. They may make reference to and contain images (for example), which are
stored in the directory beneath them _sisu/image. 〔b¤SiSU
.I plaintext
markup files are of three types that may be distinguished by the file extension
used: regular text .sst; master documents, composite documents that incorporate
other text, which can be any regular text or text insert; and inserts the
contents of which are like regular text except these are marked .ssi and are
not processed.

.BR

.B SiSU
processing can be done directly against a sisu documents; which may be located
locally or on a remote server for which a url is provided.

.BR

.B SiSU
source markup can be shared with the command:

.BR
  sisu -s [filename]
.SH SISU TEXT - REGULAR FILES (.SST)


.BR
The most common form of document in
.B SiSU,
see the section on
.B SiSU
markup.
.SH SISU MASTER FILES (.SSM)


.BR
Composite documents which incorporate other
.B SiSU
documents which may be either regular
.B SiSU
text .sst which may be generated independently, or inserts prepared solely for
the purpose of being incorporated into one or more master documents.

.BR
The mechanism by which master files incorporate other documents is described as
one of the headings under under
.B SiSU
markup in the
.B SiSU
manual.

.BR
Note: Master documents may be prepared in a similar way to regular documents,
and processing will occur normally if a .sst file is renamed .ssm without
requiring any other documents; the .ssm marker flags that the document may
contain other documents.

Note: a secondary file of the composite document is built prior to processing
with the same prefix and the suffix ._sst
.SH SISU INSERT FILES (.SSI)


.BR
Inserts are documents prepared solely for the purpose of being incorporated
into one or more master documents. They resemble regular
.B SiSU
text files (.sst). Since sisu -5.5.0 (6.1.0) .ssi files can like .ssm files
include other .sst or .ssm files. .ssi files cannot be called by the sisu
processor directly and can only be incorporated in other documents. Making a
file a .ssi file is a quick and convenient way of breaking up a document that
is to be included in a master document, and flagging that the file to be
incorporated .ssi is not intended that the file should be processed on its own.
.SH SISUPOD, ZIPPED BINARY CONTAINER (SISUPOD.ZIP, .SSP)


.BR
A sisupod is a zipped
.B SiSU
text file or set of
.B SiSU
text files and any associated images that they contain (this will be extended
to include sound and multimedia-files)
.TP
.B SiSU
.I plaintext
files rely on a recognised directory structure to find contents such as images
associated with documents, but all images for example for all documents
contained in a directory are located in the sub-directory _sisu/image. Without
the ability to create a sisupod it can be inconvenient to manually identify all
other files associated with a document. A sisupod automatically bundles all
associated files with the document that is turned into a pod.

.BR
The structure of the sisupod is such that it may for example contain a single
document and its associated images; a master document and its associated
documents and anything else; or the zipped contents of a whole directory of
prepared
.B SiSU
documents.

.BR
The command to create a sisupod is:

.BR
  sisu -S [filename]

.BR
Alternatively, make a pod of the contents of a whole directory:

.BR
  sisu -S

.BR

.B SiSU
processing can be done directly against a sisupod; which may be located locally
or on a remote server for which a url is provided.

.SH CONFIGURATION

.SH CONFIGURATION FILES

.SH CONFIG.YML


.BR

.B SiSU
configration parameters are adjusted in the configuration file, which can be
used to override the defaults set. This includes such things as which directory
interim processing should be done in and where the generated output should be
placed.

.BR
The
.B SiSU
configuration file is a yaml file, which means indentation is significant.

.BR

.B SiSU
resource configuration is determined by looking at the following files if they
exist:

.BR
  ./_sisu/v7/sisurc.yml

.BR
  ./_sisu/sisurc.yml

.BR
  ~/.sisu/v7/sisurc.yml

.BR
  ~/.sisu/sisurc.yml

.BR
  /etc/sisu/v7/sisurc.yml

.BR
  /etc/sisu/sisurc.yml

.BR
The search is in the order listed, and the first one found is used.

.BR
In the absence of instructions in any of these it falls back to the internal
program defaults.

.BR
Configuration determines the output and processing directories and the database
access details.

.BR
If
.B SiSU
is installed a sample sisurc.yml may be found in /etc/sisu/sisurc.yml
.SH SISU_DOCUMENT_MAKE


.BR
Most sisu document headers relate to metadata, the exception is the @make:
header which provides processing related information. The default contents of
the @make header may be set by placing them in a file sisu_document_make.

.BR
The search order is as for resource configuration:

.BR
  ./_sisu/v7/sisu_document_make

.BR
  ./_sisu/sisu_document_make

.BR
  ~/.sisu/v7/sisu_document_make

.BR
  ~/.sisu/sisu_document_make

.BR
  /etc/sisu/v7/sisu_document_make

.BR
  /etc/sisu/sisu_document_make

.BR
A sample sisu_document_make can be found in the _sisu/ directory under along
with the provided sisu markup samples.
.SH CSS - CASCADING STYLE SHEETS (FOR HTML, XHTML AND XML)


.BR
CSS files to modify the appearance of
.B SiSU
html,
.I XHTML
or
.I XML
may be placed in the configuration directory: ./_sisu/css ; ~/.sisu/css or;
/etc/sisu/css and these will be copied to the output directories with the
command sisu -CC.

.BR
The basic CSS file for html output is html. css, placing a file of that name in
directory _sisu/css or equivalent will result in the default file of that name
being overwritten.

.BR

.I HTML:
html. css

.BR

.I XML
DOM: dom.css

.BR

.I XML
SAX: sax.css

.BR

.I XHTML:
xhtml. css

.BR
The default homepage may use homepage.css or html. css

.BR
Under consideration is to permit the placement of a CSS file with a different
name in directory _sisu/css directory or equivalent.[^12]
.SH ORGANISING CONTENT - DIRECTORY STRUCTURE AND MAPPING


.BR

.B SiSU
v3 has new options for the source directory tree, and output directory
structures of which there are 3 alternatives.
.SH DOCUMENT SOURCE DIRECTORY


.BR
The document source directory is the directory in which sisu processing
commands are given. It contains the sisu source files (.sst .ssm .ssi), or (for
sisu v3 may contain) subdirectories with language codes which contain the sisu
source files, so all English files would go in subdirectory en/, French in fr/,
Spanish in es/ and so on. ISO 639-1 codes are used (as varied by po4a). A list
of available languages (and possible sub-directory names) can be obtained with
the command "sisu --help lang" The list of languages is limited to langagues
supported by XeTeX polyglosia.
.SH GENERAL DIRECTORIES

.nf
 ./subject_name/

% files stored at this level e.g. sisu_manual.sst or
% for sisu v3 may be under language sub-directories
% e.g.

 ./subject_name/en

 ./subject_name/fr

 ./subject_name/es

 ./subject_name/_sisu

 ./subject_name/_sisu/css

 ./subject_name/_sisu/image
.fi

.SH DOCUMENT OUTPUT DIRECTORY STRUCTURES

.SH OUTPUT DIRECTORY ROOT


.BR
The output directory root can be set in the sisurc.yml file. Under the root,
subdirectories are made for each directory in which a document set resides. If
you have a directory named poems or conventions, that directory will be created
under the output directory root and the output for all documents contained in
the directory of a particular name will be generated to subdirectories beneath
that directory (poem or conventions). A document will be placed in a
subdirectory of the same name as the document with the filetype identifier
stripped (.sst .ssm)

.BR
The last part of a directory path, representing the sub-directory in which a
document set resides, is the directory name that will be used for the output
directory. This has implications for the organisation of document collections
as it could make sense to place documents of a particular subject, or type
within a directory identifying them. This grouping as suggested could be by
subject (sales_law, english_literature); or just as conveniently by some other
classification (X University). The mapping means it is also possible to place
in the same output directory documents that are for organisational purposes
kept separately, for example documents on a given subject of two different
institutions may be kept in two different directories of the same name, under a
directory named after each institution, and these would be output to the same
output directory. Skins could be associated with each institution on a
directory basis and resulting documents will take on the appropriate different
appearance.
.SH ALTERNATIVE OUTPUT STRUCTURES


.BR
There are 3 possibile output structures described as being, by language, by
filetype or by filename, the selection is made in sisurc.yml
.nf
#% output_dir_structure_by: language; filetype; or filename

.SH HOMEPAGES


.BR

.B SiSU
is about the ability to auto-generate documents. Home pages are regarded as
custom built items, and are not created by
.B SiSU.
More accurately,
.B SiSU
has a default home page, which will not be appropriate for use with other
sites, and the means to provide your own home page instead in one of two ways
as part of a site's configuration, these being:

.BR
1. through placing your home page and other custom built documents in the
subdirectory _sisu/home/ (this probably being the easier and more convenient
option)

.BR
2. through providing what you want as the home page in a skin,

.BR
Document sets are contained in directories, usually organised by site or
subject. Each directory can/should have its own homepage. See the section on
directory structure and organisation of content.
.SH HOME PAGE AND OTHER CUSTOM BUILT PAGES IN A SUB-DIRECTORY


.BR
Custom built pages, including the home page index.html may be placed within the
configuration directory _sisu/home/ in any of the locations that is searched
for the configuration directory, namely ./_sisu ; ~/_sisu ; /etc/sisu From
there they are copied to the root of the output directory with the command:

.BR
  sisu -CC
.SH MARKUP AND OUTPUT EXAMPLES

.SH MARKUP EXAMPLES


.BR
Current markup examples and document output samples are provided off
<https://sisudoc.org> or <https://www.jus.uio.no/sisu> and in the sisu
-markup-sample package available off <https://git.sisudoc.org>

.BR
For some documents hardly any markup at all is required at all, other than a
header, and an indication that the levels to be taken into account by the
program in generating its output are.
.SH SISU MARKUP SAMPLES


.BR
A few additional sample books prepared as sisu markup samples, output formats
to be generated using
.B SiSU
are contained in a separate package sisu -markup-samples. sisu -markup-samples
contains books (prepared using sisu markup), that were released by their
authors various licenses mostly different Creative Commons licences that do not
permit inclusion in the
.B Debian
Project as they have requirements that do not meet the
.B Debian
Free Software Guidelines for various reasons, most commonly that they require
that the original substantive text remain unchanged, and sometimes that the
works be used only non-commercially.

.SH SISU SEARCH - INTRODUCTION


.BR
Because the document structure of sites created is clearly defined, and the
text
.I object citation system
is available hypothetically at least, for all forms of output, it is possible
to search the sql database, and either read results from that database, or map
the results to the html or other output, which has richer text markup.

.BR

.B SiSU
can populate a relational sql type database with documents at an object level,
including objects numbers that are shared across different output types. Making
a document corpus searchable with that degree of granularity. Basically, your
match criteria is met by these documents and at these locations within each
document, which can be viewed within the database directly or in various output
formats.

.BR

.B SiSU
can populate an sql database (sqlite3 or postgresql) with documents made up of
their objects. It also can generate a cgi search form that can be used to query
the database.

.BR
In order to use the built in search functionality you would take the following
steps.

.BR
- use sisu to populate an sql database with with a sisu markup content

.BR
  * sqlite3 should work out of the box

.BR
  * postgresql may require some initial database configuration

.BR
- provide a way to query the database, which sisu can assist with by

.BR
  * generating a sample ruby cgi search form, required (sisu configuration
  recommended)

.BR
  * adding a query field for this search form to be added to all html files
  (sisu configuration required)
.SH SQL

.SH POPULATE THE DATABASE


.BR
TO populate the sql database, run sisu against a sisu markup file with one of
the following sets of flags
.nf
sisu --sqlite filename.sst
.fi


.BR
creates an sqlite3 database containing searchable content of just the sisu
markup document selected
.nf
sisu --sqlite --update filename.sst
.fi


.BR
creates an sqlite3 database containing searchable content of marked up
document(s) selected by the user from a common directory
.nf
sisu --pg --update filename.sst
.fi


.BR
fills a postgresql database with searchable content of marked up document(s)
selected by the user from a common directory

.BR
For postgresql the first time the command is run in a given directory the user
will be prompted to create the requisite database, at the time of writing the
prompt sisu provides is as follows:
.nf
no connection with pg database established, you may need to run:
    createdb "SiSU.7a.current"
  after that don't forget to run:
    sisu --pg --createall
  before attempting to populate the database
.fi


.BR
The named database that sisu expects to find must exist and if necessary be
created using postgresql tools. If the database exist but the database tables
do not, sisu will attempt to create the tables it needs, the equivalent of the
requested sisu --pg --createall command.

.BR
Once this is done, the sql database is populated and ready to be queried.
.SH SQL TYPE DATABASES


.BR

.B SiSU
feeds sisu markup documents into sql type databases
.I PostgreSQL
[^13] and/or
.I SQLite
[^14] database together with information related to document structure.

.BR
This is one of the more interesting output forms, as all the structural data of
the documents are retained (though can be ignored by the user of the database
should they so choose). All site texts/documents are (currently) streamed to
four tables:

.BR
  * one containing semantic (and other) headers, including, title, author,
  subject, (the
  .I Dublin Core.
  ..);

.BR
  * another the substantive texts by individual "paragraph" (or object) - along
  with structural information, each paragraph being identifiable by its
  paragraph number (if it has one which almost all of them do), and the
  substantive text of each paragraph quite naturally being searchable (both in
  formatted and clean text versions for searching); and

.BR
  * a third containing endnotes cross-referenced back to the paragraph from
  which they are referenced (both in formatted and clean text versions for
  searching).

.BR
  * a fourth table with a one to one relation with the headers table contains
  full text versions of output, eg. pdf, html, xml, and
  .I ascii.

.BR
There is of course the possibility to add further structures.

.BR
At this level
.B SiSU
loads a relational database with documents chunked into objects, their smallest
logical structurally constituent parts, as text objects, with their object
citation number and all other structural information needed to construct the
document. Text is stored (at this text object level) with and without
elementary markup tagging, the stripped version being so as to facilitate ease
of searching.

.BR
Being able to search a relational database at an object level with the
.B SiSU
citation system is an effective way of locating content generated by
.B SiSU.
As individual text objects of a document stored (and indexed) together with
object numbers, and all versions of the document have the same numbering,
complex searches can be tailored to return just the locations of the search
results relevant for all available output formats, with live links to the
precise locations in the database or in html/xml documents; or, the structural
information provided makes it possible to search the full contents of the
database and have headings in which search content appears, or to search only
headings etc. (as the
.I Dublin Core
is incorporated it is easy to make use of that as well).

.SH CGI SEARCH FORM


.BR
For the search form, which is a single search page

.BR
- configure the search form

.BR
- generate the sample search form with the sisu command, (this will be based on
the configuration settings and existing found sisu databases)

.BR
For postgresql web content you may need to edit the search cgi script. Two
things to look out for are that the user is set as needed, and that the any
different databases that you wish to be able to query are listed.

.BR
correctly, you may want www-data rather than your username.
.nf
@user='www-data'
.fi


.BR
- check the search form, copy it to the appropriate cgi directory and set the
correct permissions

.BR
For a search form to appear on each html page, you need to:

.BR
- rely on the above mentioned configuration of the search form

.BR
- configure the html search form to be on

.BR
- run the html command
.SH SETUP SEARCH FORM


.BR
You will need a web server, httpd with cgi enabled, and a postgresql database
to which you are able to create databases.

.BR
Setup postgresql, make sure you are able to create and write to the database,
e.g.:
.nf
sudo su postgres
  createuser -d -a ralph

You then need to create the database that sisu will use, for sisu manual in the
directory manual/en for example, (when you try to populate a database that does
not exist sisu prompts as to whether it exists):
.nf
createdb SiSU.7a.manual
.fi


.BR

.B SiSU
is then able to create the required tables that allow you to populate the
database with documents in the directory for which it has been created:
.nf
sisu --pg --createall -v
.fi


.BR
You can then start to populate the database, in this example with a single
document:
.nf
sisu --pg --update -v en/sisu_manual.ssm
.fi


.BR
To create a sample search form, from within the same directory run:
.nf
sisu --sample-search-form --db-pg
.fi


.BR
and copy the resulting cgi form to your cgi-bin directory

A sample setup for nginx is provided that assumes data will be stored under

.BR
Sample search frontend <https://search.sisudoc.org> [^15] A small database and
sample query front-end (search from) that makes use of the citation system, .I
object citation numbering
to demonstrates functionality.[^16]

.BR

.B SiSU
can provide information on which documents are matched and at what locations
within each document the matches are found. These results are relevant across
all outputs using
.I object citation numbering,
which includes html,
.I XML,
.I EPUB,
.I LaTeX,
.I PDF
and indeed the
.I SQL
database. You can then refer to one of the other outputs or in the
.I SQL
database expand the text within the matched objects (paragraphs) in the
documents matched.

.BR
Note you may set results either for documents matched and object number
locations within each matched document meeting the search criteria; or display
the names of the documents matched along with the objects (paragraphs) that
meet the search criteria.[^17]

Note on databases built

.BR
By default, [unless otherwise specified] databases are built on a directory
basis, from collections of documents within that directory. The name of the
directory you choose to work from is used as the database name, i.e. if you are
working in a directory called /home/ralph/ebook the database SiSU_ebook is
used. [otherwise a manual mapping for the collection is necessary]

.SH SEARCH FORM

.SH SUMMARY OF FEATURES


.BR
- sparse/minimal markup (clean utf-8 source texts). Documents are prepared in a
single
.I UTF-8
file using a minimalistic mnemonic syntax. Typical literature, documents like
"War and Peace" require almost no markup, and most of the headers are optional.

.BR
- markup is easily readable/parsable by the human eye, (basic markup is simpler
and more sparse than the most basic
.I HTML
) , [this may also be converted to
.I XML
representations of the same input/source document].

.BR
- markup defines document structure (this may be done once in a header
pattern-match description, or for heading levels individually); basic text
attributes (bold, italics, underscore, strike-through etc.) as required; and
semantic information related to the document (header information, extended
beyond the Dublin core and easily further extended as required); the headers
may also contain processing instructions.
.B SiSU
markup is primarily an abstraction of document structure and document metadata
to permit taking advantage of the basic strengths of existing alternative
practical standard ways of representing documents [be that browser viewing,
paper publication, sql search etc.] (html, epub, xml, odf, latex, pdf, sql)

.BR
- for output produces reasonably elegant output of established industry and
institutionally accepted open standard formats.[3] takes advantage of the
different strengths of various standard formats for representing documents,
amongst the output formats currently supported are:

.BR
*
.I HTML
- both as a single scrollable text and a segmented document

.BR
*
.I XHTML

.BR
*
.I EPUB

.BR
*
.I XML
- both in sax and dom style xml structures for further development as required

.BR
*
.I ODT
- Open Document Format text, the iso standard for document storage

.BR
*
.I LaTeX
- used to generate pdf

.BR
*
.I PDF
(via
.I LaTeX
)

.BR
*
.I SQL
- population of an sql database (
.I PostgreSQL
or
.I SQLite
) , (at the same object level that is used to cite text within a document)

.BR
Also produces: concordance files; document content certificates (md5 or sha256
digests of headings, paragraphs, images etc.) and html manifests (and sitemaps
of content). (b) takes advantage of the strengths implicit in these very
different output types, (e.g. PDFs produced using typesetting of
.I LaTeX,
databases populated with documents at an individual object/paragraph level,
making possible
.I granular search
(and related possibilities))

.BR
- ensuring content can be cited in a meaningful way regardless of selected
output format. Online publishing (and publishing in multiple document formats)
lacks a useful way of citing text internally within documents (important to
academics generally and to lawyers) as page numbers are meaningless across
browsers and formats. sisu seeks to provide a common way of pinpoint the text
within a document, (which can be utilized for citation and by search engines).
The outputs share a common numbering system that is meaningful (to man and
machine) across all digital outputs whether paper, screen, or database
oriented, (pdf,
.I HTML,
.I EPUB,
xml, sqlite, postgresql) , this numbering system can be used to reference
content.

.BR
- Granular search within documents.
.I SQL
databases are populated at an object level (roughly headings, paragraphs,
verse, tables) and become searchable with that degree of granularity, the
output information provides the object/paragraph numbers which are relevant
across all generated outputs; it is also possible to look at just the matching
paragraphs of the documents in the database; [output indexing also work well
with search indexing tools like hyperestraier].

.BR
- long term maintainability of document collections in a world of changing
formats, having a very sparsely marked-up source document base. there is a
considerable degree of future-proofing, output representations are
"upgradeable", and new document formats may be added. e.g. addition of odf
(open document text) module in 2006, epub in 2009 and in future html5 output
sometime in future, without modification of existing prepared texts

.BR
*
.I SQL
search aside, documents are generated as required and static once generated.

.BR
- documents produced are static files, and may be batch processed, this needs
to be done only once but may be repeated for various reasons as desired
(updated content, addition of new output formats, updated technology document
presentations/representations)

.BR
- document source (
.I plaintext
utf-8) if shared on the net may be used as input and processed locally to
produce the different document outputs

.BR
- document source may be bundled together (automatically) with associated
documents (multiple language versions or master document with inclusions) and
images and sent as a zip file called a sisupod, if shared on the net these too
may be processed locally to produce the desired document outputs

.BR
- generated document outputs may automatically be posted to remote sites.

.BR
- for basic document generation, the only software dependency is
.B Ruby,
and a few standard Unix tools (this covers
.I plaintext,
.I HTML,
.I EPUB,
.I XML,
.I ODF,
.I LaTeX
) . To use a database you of course need that, and to convert the
.I LaTeX
generated to pdf, a latex processor like tetex or texlive.

.BR
- as a developers tool it is flexible and extensible

.BR
Syntax highlighting for
.B SiSU
markup is available for a number of text editors.

.BR

.B SiSU
is less about document layout than about finding a way with little markup to be
able to construct an abstract representation of a document that makes it
possible to produce multiple representations of it which may be rather
different from each other and used for different purposes, whether layout and
publishing, or search of content

.BR
i.e. to be able to take advantage from this minimal preparation starting point
of some of the strengths of rather different established ways of representing
documents for different purposes, whether for search (relational database, or
indexed flat files generated for that purpose whether of complete documents, or
say of files made up of objects), online viewing (e.g. html, xml, pdf) , or
paper publication (e.g. pdf) ...

.BR
the solution arrived at is by extracting structural information about the
document (about headings within the document) and by tracking objects (which
are serialized and also given hash values) in the manner described. It makes
possible representations that are quite different from those offered at
present. For example objects could be saved individually and identified by
their hashes, with an index of how the objects relate to each other to form a
document.

of this feature when demonstrated to an IBM software innovations evaluator
in 2004 he said to paraphrase: this could be of interest to us. We have large
document management systems, you can search hundreds of thousands of documents
and we can tell you which documents meet your search criteria, but there is no
way we can tell you without opening each document where within each your
matches are found.
