INTRODUCTION - WHAT IS SISU? +------------------------------- + +*SiSU* is a system for document markup, publishing (in multiple open standard +formats) and search + + +*SiSU*[^1] is a[^2] framework for document structuring, publishing and search, +comprising of (a) a lightweight document structure and presentation markup +syntax and (b) an accompanying engine for generating standard document format +outputs from documents prepared in sisu markup syntax, which is able to produce +multiple standard outputs that (can) share a common numbering system for the +citation of text within a document. + + +- [1]: "*SiSU* information Structuring Universe" or "Structured information, + Serialized Units". + +- also chosen for the meaning of the Finnish term "sisu". + +- [2]: Unix command line oriented + +*SiSU* is developed under an open source, software libre license (GPL3). It has +been developed in the context of coping with large document sets with evolving +markup related technologies, for which you want multiple output formats, a +common mechanism for cross-output-format citation, and search. + + +*SiSU* both defines a markup syntax and provides an engine that produces open +standards format outputs from documents prepared with *SiSU* markup. From a +single lightly prepared document 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. Significantly *SiSU* markup is more sparse than html and outputs +which include html, LaTeX, landscape and portrait pdfs, Open Document Format +(ODF), all of which can be added to and updated. *SiSU* is also able to +populate SQL type databases at an object level, which means that searches can +be made with that degree of granularity. Results of objects (primarily +paragraphs and headings) can be viewed directly in the database, or just the +object numbers shown - your search criteria is met in these documents and at +these locations within each document. + + +Source document preparation and output generation is a two step process: (i) +document source is prepared, that is, marked up in sisu markup syntax and (ii) +the desired output subsequently generated by running the sisu engine against +document source. Output representations if updated (in the sisu engine) can be +generated by re-running the engine against the prepared source. Using *SiSU* +markup applied to a document, *SiSU* custom builds various standard open output +formats including plain text, HTML, XHTML, XML, OpenDocument, LaTeX or PDF +files, and populate an SQL database with objects[^3] (equating generally to +paragraph-sized chunks) so searches may be performed and matches returned with +that degree of granularity ( e.g. your search criteria is met by these +documents and at these locations within each document). Document output formats +share a common object numbering system for locating content. This is +particularly suitable for "published" works (finalized texts as opposed to +works that are frequently changed or updated) for which it provides a fixed +means of reference of content. + + +- [3]: objects include: headings, paragraphs, verse, tables, images, but not + footnotes/endnotes which are numbered separately and tied to the object from + which they are referenced. + +In preparing a *SiSU* document you optionally provide semantic information +related to the document in a document header, and in marking up the substantive +text provide information on the structure of the document, primarily indicating +heading levels and footnotes. You also provide information on basic text +attributes where used. The rest is automatic, sisu from this information custom +builds[^4] the different forms of output requested. + + +- [4]: i.e. the html, pdf, odf outputs are each built individually and optimised + for that form of presentation, rather than for example the html being a saved + version of the odf, or the pdf being a saved version of the html. + +*SiSU* works with an abstraction of the document based on its structure which +is comprised of its frame[^5] and the objects[^6] it contains, which enables +*SiSU* to represent the document in many different ways, and to take advantage +of the strengths of different ways of presenting documents. The objects are +numbered, and these numbers can be used to provide a common base for citing +material within a document across the different output format types. This is +significant as page numbers are not suited to the digital age, in web +publishing, changing a browser's default font or using a different browser +means that text appears on different pages; and in publishing in different +formats, html, landscape and portrait pdf etc. again page numbers are of no use +to cite text in a manner that is relevant against the different output types. +Dealing with documents at an object level together with object numbering also +has implications for search. + + +- [5]: the different heading levels + +- [6]: units of text, primarily paragraphs and headings, also any tables, poems, + code-blocks + +One of the challenges of maintaining documents is to keep them in a format that +would allow users to use them without depending on a proprietary software +popular at the time. Consider the ease of dealing with legacy proprietary +formats today and what guarantee you have that old proprietary formats will +remain (or can be read without proprietary software/equipment) in 15 years +time, or the way the way in which html has evolved over its relatively short +span of existence. *SiSU* provides the flexibility of outputing documents in +multiple non-proprietary open formats including html, pdf[^7] and the ISO +standard ODF.[^8] Whilst *SiSU* relies on software, the markup is uncomplicated +and minimalistic which guarantees that future engines can be written to run +against it. It is also easily converted to other formats, which means documents +prepared in *SiSU* can be migrated to other document formats. Further security +is provided by the fact that the software itself, *SiSU* is available under +GPL3 a licence that guarantees that the source code will always be open, and +free as in libre which means that that code base can be used updated and +further developed as required under the terms of its license. Another challenge +is to keep up with a moving target. *SiSU* permits new forms of output to be +added as they become important, (Open Document Format text was added in 2006), +and existing output to be updated (html has evolved and the related module has +been updated repeatedly over the years, presumably when the World Wide Web +Consortium (w3c) finalises html 5 which is currently under development, the +html module will again be updated allowing all existing documents to be +regenerated as html 5). + + +- [7]: Specification submitted by Adobe to ISO to become a full open ISO + specification + +- + +- [8]: ISO/IEC 26300:2006 + +The document formats are written to the file-system and available for indexing +by independent indexing tools, whether off the web like Google and Yahoo or on +the site like Lucene and Hyperestraier. + + +*SiSU* also provides other features such as concordance files and document +content certificates, and the working against an abstraction of document +structure has further possibilities for the research and development of other +document representations, the availability of objects is useful for example for +topic maps and the commercial law thesaurus by Vikki Rogers and Al Krtizer, +together with the flexibility of *SiSU* offers great possibilities. + + +*SiSU* is primarily for published works, which can take advantage of the +citation system to reliably reference its documents. *SiSU* works well in a +complementary manner with such collaborative technologies as Wikis, which can +take advantage of and be used to discuss the substance of content prepared in +*SiSU*. + + + + + +2. HOW DOES SISU WORK? +---------------------- + +*SiSU* markup is fairly minimalistic, it consists of: a (largely optional) +document header, made up of information about the document (such as when it was +published, who authored it, and granting what rights) and any processing +instructions; and markup within the substantive text of the document, which is +related to document structure and typeface. *SiSU* must be able to discern the +structure of a document, (text headings and their levels in relation to each +other), either from information provided in the document header or from markup +within the text (or from a combination of both). Processing is done against an +abstraction of the document comprising of information on the document's +structure and its objects,[2] which the program serializes (providing the +object numbers) and which are assigned hash sum values based on their content. +This abstraction of information about document structure, objects, (and hash +sums), provides considerable flexibility in representing documents different +ways and for different purposes (e.g. search, document layout, publishing, +content certification, concordance etc.), and makes it possible to take +advantage of some of the strengths of established ways of representing +documents, (or indeed to create new ones). + + +3. SUMMARY OF FEATURES +---------------------- + +* sparse/minimal markup (clean utf-8 source texts). Documents are prepared in a +single 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. + + +* markup is easily readable/parsable by the human eye, (basic markup is simpler +and more sparse than the most basic HTML), [this may also be converted to XML +representations of the same input/source document]. + + +* 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. *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, xml, odf, latex, pdf, sql) + + +* 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: + + + * html - both as a single scrollable text and a segmented document + + + * xhtml + + + * XML - both in sax and dom style xml structures for further development as + required + + + * ODF - open document format, the iso standard for document storage + + + * LaTeX - used to generate pdf + + + * pdf (via LaTeX) + + + * sql - population of an sql database, (at the same object level that is used + to cite text within a document) + + +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 LaTeX, +databases populated with documents at an individual object/paragraph level, +making possible granular search (and related possibilities)) + + +* 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, HTML, xml, sqlite, postgresql), this numbering system can be +used to reference content. + + +* Granular search within documents. 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]. + + +* 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 and in future html5 output sometime in +future, without modification of existing prepared texts + + +* SQL search aside, documents are generated as required and static once +generated. + + +* 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) + + +* document source (plaintext utf-8) if shared on the net may be used as input +and processed locally to produce the different document outputs + + +* 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 + + +* generated document outputs may automatically be posted to remote sites. + + +* for basic document generation, the only software dependency is *Ruby*, and a +few standard Unix tools (this covers plaintext, HTML, XML, ODF, LaTeX). To use +a database you of course need that, and to convert the LaTeX generated to pdf, +a latex processor like tetex or texlive. + + +* as a developers tool it is flexible and extensible + + +Syntax highlighting for *SiSU* markup is available for a number of text +editors. + + +*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 + + +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)... + + +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. + + +DOCUMENT INFORMATION (METADATA) +******************************* + +METADATA +-------- + +Document Manifest @ + + + +*Dublin Core* (DC) + + +/DC tags included with this document are provided here./ + + +DC Title: _SiSU - Commands [0.58]_ + + +DC Creator: _Ralph Amissah_ + + +DC Rights: _Copyright (C) Ralph Amissah 2007, part of SiSU documentation, +License GPL 3_ + + +DC Type: _information_ + + +DC Date created: _2002-08-28_ + + +DC Date issued: _2002-08-28_ + + +DC Date available: _2002-08-28_ + + +DC Date modified: _2007-09-16_ + + +DC Date: _2007-09-16_ + + +*Version Information* + + +Sourcefile: _sisu_introduction.sst_ + + +Filetype: _SiSU text 0.58_ + + +Sourcefile Digest, MD5(sisu_introduction.sst)= +_b2a6da5bd22fa1eaa92a08d81f11d1c7_ + + +Skin_Digest: +MD5(/home/ralph/grotto/theatre/dbld/sisu-dev/sisu/data/doc/sisu/sisu_markup_samples/sisu_manual/_sisu/skin/doc/skin_sisu_manual.rb)= +_20fc43cf3eb6590bc3399a1aef65c5a9_ + + +*Generated* + + +Document (metaverse) last generated: _Sun Sep 23 04:10:58 +0100 2007_ + + +Generated by: _SiSU_ _0.59.0_ of 2007w38/0 (2007-09-23) + + +Ruby version: _ ruby 1.8.6 (2007-06-07 patchlevel 36) [i486-linux]_ + + + +============================================================================== + + title: SiSU - Commands [0.58] + + creator: Ralph Amissah + + rights: Copyright (C) Ralph Amissah 2007, part of SiSU documentation, + License GPL 3 + + type: information + + subject: ebook, epublishing, electronic book, electronic publishing, + electronic document, electronic citation, data structure, + citation systems, search + + date.created: 2002-08-28 + + date.issued: 2002-08-28 + + date.available: 2002-08-28 + + date.modified: 2007-09-16 + + date: 2007-09-16 + + + + + +============================================================================== +nil + +Other versions of this document: +manifest: + http://www.jus.uio.no/sisu/sisu_introduction/sisu_manifest.html +html: + http://www.jus.uio.no/sisu/sisu_introduction/toc.html +pdf: + http://www.jus.uio.no/sisu/sisu_introduction/portrait.pdf + http://www.jus.uio.no/sisu/sisu_introduction/landscape.pdf +plaintext (plain text): + http://www.jus.uio.no/sisu/sisu_introduction/plain.txt +at: + http://www.jus.uio.no/sisu +* Generated by: SiSU 0.59.0 of 2007w38/0 (2007-09-23) +* Ruby version: ruby 1.8.6 (2007-06-07 patchlevel 36) [i486-linux] +* Last Generated on: Sun Sep 23 04:11:49 +0100 2007 +* SiSU http://www.jus.uio.no/sisu -- cgit v1.2.3
