Other than the source code for the SWORD API, there is no documentation for the file format of a '''SWORD module'''. There is no other documentation. The intention is that the [[DevTools:SWORD|SWORD API]] (or the [[DevTools:JSword|JSword]] implementation) is used directly or via other [http://en.wikipedia.org/wiki/Language_binding language bindings].

Whilst our software is [http://en.wikipedia.org/wiki/Open_source ''open source''], our module file format is [http://en.wikipedia.org/wiki/Proprietary_format ''proprietary''], in the sense that we see no need to document it and certainly no need to stick to it. We change it when we need to. We therefore do not encourage direct interaction with it, but firmly recommend use of the API (either C++ or Java). This is the place where we seek stability and consistency.

−
==SWORD Input formats==
 
−
The SWORD Project supports the following markup: OSIS, TEI, ThML, GBF and plain text.
 
−
 
 
−
===OSIS===
 
−
''Open Scripture Information Standard''
 
−
 
 
−
The Open Scripture Information Standard (OSIS) is "a common format for many visions." It is an XML format for marking up scripture and related text, part of an initiative composed of translators, publishers, scholars, software manufacturers, and technical experts, coordinated by the [http://www.bibletechnologies.net/ Bible Technologies Group]. It is co-sponsored by the [http://www.americanbible.org/ American Bible Society] and the [http://www.sbl-site.org/ Society of Biblical Literature].
 
−
 
 
−
The most recent XML schema is [http://www.bibletechnologies.net/osisCore.2.1.1.xsd OSIS 2.1.1], and a [http://www.bibletechnologies.net/20Manual.dsp manual]  is also available.
 
−
 
 
−
This markup format is recommended by the CrossWire Bible Society and can be used for creating all types of resources for The SWORD Project. Support for OSIS is actively maintained and support for any unsupported elements or features needed for a module you may be working on may be requested.
 
−
 
 
−
[http://www.princexml.com/ Prince XML] is a proprietary software program that converts XML and HTML documents into PDF files by applying Cascading Style Sheets (CSS). It is developed by YesLogic, a small company based in Melbourne, Australia. It can be used to create high quality PDF Bibles from OSIS files[http://www.princexml.com/samples/]. A paper by [http://www.bibletechconference.com/speakers/ Jim Albright] of Wycliffe Bible Translators was presented at [http://www.bibletechconference.com/ BibleTech 2010] on using the open-source GUI companion for Prince XML, called [http://code.google.com/p/princess-2010/ Princess].
 
−
 
 
−
===TEI P5===
 
−
''Text Encoding Initiative''
 
−
 
 
−
TEI is an text encoding standard used broadly in the humanities. It is developed by the [http://www.tei-c.org/ TEI Consortium].
 
−
 
 
−
A manual for the latest edition of TEI P5 can be found at [http://www.tei-c.org/release/doc/tei-p5-doc/en/html/ P5: Guidelines for Electronic Text Encoding and Interchange].
 
−
 
 
−
CrossWire supports use of TEI for the encoding of dictionaries, encyclopedias, and similar works, as well as for free form books (GenBooks). We have developed our own version of the TEI P5 schema, available at http://www.crosswire.org/osis/teiP5osis.latest.xsd (http://www.crosswire.org/osis/teiP5osis.2.5.0.xsd is the latest at the time of writing). CrossWire's additions to the standard schema include the ability to create osisRefs and osisIDs to facilitate interoperability with OSIS documents and Bible reference tagging.

−
Further information can be found at the [[TEI Dictionaries]] page.
 
−
 
 
−
===VPL===
 
−
''Verse-Per-Line''
 
−
 
 
−
This plain-text format is used for by SWORD for import of Bibles. It consists of one verse per line, with an optional verse reference at the beginning. The [[#VPL_Tools|vpl2mod]] utility may be used for import. VPL is deprecated in favor of the IMP format, which is more widely useful. The [[#VPL_Tools|mod2vpl]] utility may be used for export to VPL. There is a command line switch to prepend the verse reference to each line.
 
−
 
 
−
===IMP===
 
−
''Import Format''
 
−
 
 
−
This proprietary file format is used by SWORD for import of all types of modules. The three utilities '''imp2vs''' (for Bibles and verse-indexed commentaries), '''imp2ld''' (for lexicons, dictionaries, and daily-devotionals), and '''imp2gbs''' (for all other types of books) can be used to import IMP files to SWORD's native formats.
 
−
 
 
−
An IMP file consists of any number of entries. Each entry consists of a key line and any number of content lines. The key line consists of a line beginning with "$$$". For example, "$$$Gen 1:1" would be the key line for the Genesis 1:1 entry of a Bible or commentary module.
 
−
 
 
−
The content lines of an entry may consist of any text (provided that the first three characters of the line are not "$$$"). The internal markup of the content may be in any format supported by SWORD, namely OSIS for any module type or ThML for freeform books from CCEL.

==== imp2osis ====
 
−
CrossWire has a Perl script called [http://crosswire.org/ftpmirror/pub/sword/utils/perl/imp2osis.pl imp2osis.pl], which will convert IMP to OSIS fairly well (except a few 'corner cases'). Whenever CrossWire receives an IMP submission, this is the first thing that is run, allowing CrossWire to do validation and other OSIS sanity checks. Some editing is usually necessary after converting an IMP file to an OSIS XML file. For example, the attribute '''canonical''' is omitted from the osisText and all &lt;div> elements, and the language attribute '''xml:lang''' defaults to "en".
 
−
 
 
−
===ThML===
 
−
''Theological Markup Language'' '''(deprecated)'''
 
−
 
 
−
This format is a variant of XML based on TEI and ThML, developed by and for the [http://www.ccel.org/ Christian Classics Ethereal Library]. The specifications for this markup format are available at http://www.ccel.org/ThML/.
 
−
 
 
−
This markup format is used in some SWORD resources, but only the creation of free-form "General book" modules based on existing CCEL resources is currently supported. Other works and new works should be created using the OSIS or TEI format.
 
−
 
 
−
===GBF===
 
−
''General Bible Format'' '''(deprecated)'''
 
  
−
This markup format is intended as an aid to preparing Bible texts (specifically the WEB and WEB:ME) for use with various Bible search programs. The complete specification is at http://www.ebible.org/bible/gbf.htm.  
+
Our module file format is proprietary in the sense that we see no need to document it and certainly no need to stick to it. We change it when we need to. We therefore do not encourage direct interaction with it, but firmly recommend use of the API (either C++ or Java). This is the place where we seek stability and consistency.
  
−
This markup format was previously used for some SWORD modules but is now [http://en.wikipedia.org/wiki/Deprecation deprecated] in favor of OSIS. The rudimentary [http://crosswire.org/ftpmirror/pub/sword/utils/perl/gbf2osis.pl gbf2osis.pl] Perl utility may be used to convert GBF to OSIS for import to SWORD's native format. Adyeth hosts a [http://sites.google.com/site/adyeths/theswordproject/gbf2osis.py?attredirects=0 gbf2osis] Python utility that he wrote to convert the GBF texts from [http://ebible.org/ ebible.org] to OSIS. See [http://sites.google.com/site/adyeths/theswordproject].
+
The SWORD Project supports currently and actively the following markup for module creation: OSIS, [https://tei-c.org/ TEI], ThML and plain text.

The SWORD Project uses primary source e-texts. These texts come in numerous formats. CrossWire maintains converters for a number of formats, described below. The converters may target other markup formats, e.g. TEI or OSIS, or may simply export binary data to text, as is the case with our STEP exporter. Specific discussion of each of the available converters is found elsewhere on this page.

''Unbound Bible Format''
 
−
 
−
The [http://unbound.biola.edu/ BIOLA's Unbound Bible] offers many of their resources for download in a proprietary, but relatively simple [http://en.wikipedia.org/wiki/Tab_delimited tab-delimited] plain-text format (TDT). There are usually two variants, one with versification mapping to the [http://en.wikipedia.org/wiki/American_Standard_Version ASV], and the other without verse mapping. All available downloads may be found on Unbound Bible's [http://unbound.biola.edu/index.cfm?method=downloads.showDownloadMain download page].
 
−
 
−
There is no widespread use of this format, but the rudimentary [http://crosswire.org/ftpmirror/pub/sword/utils/perl/unb2osis.pl unb2osis.pl] utility may be used to convert Unbound Bible format to OSIS for import to SWORD's native format.

===Go Bible===
 
−
Following an agreement made in July 2008 with the program's author Jolon Faichney, [[Projects:Go Bible|Go Bible]] was adopted by CrossWire as its Java ME software project.
 
−
 
−
To achieve the navigation speed and general ease of use on even the simplest of Java mobile phones, Go Bible data is fully indexed, as well as being compressed (as are all JAR files).  The format is described in [http://code.google.com/p/gobible/wiki/GoBibleDataFormat Go Bible data format]. Go Bible data is structured as Book | Chapter | Verse text and does not support notes, headings and cross-references, etc. The developer kit [http://gobible.jolon.org/developer/welcome.html Go Bible Creator] can take either USFM, ThML or OSIS as the source text format, but they usually have to be made specially suitable. For example, OSIS files produced by Snowfall Software's SFMToOSIS script are not structured the same. Work has begun to make an [http://en.wikipedia.org/wiki/XSL_Transformations XSLT] script to convert such OSIS XML files to the format suitable for Go Bible. [[Projects:Go Bible/Go Bible Creator|Go Bible Creator]] version 2.3.2 and onwards can take a folder of USFM files as the source text format.

'''USX''' is an XML schema that is the underlying data structure in the latest release of [http://paratext.org/ UBS Paratext]. SIL's Language Software Development team is working with UBS on this. This version of Paratext can take in USFM projects and export USX files.
 
−
 
−
USX was defined to support the [http://everytribeeverynation.org/ Every Tribe Every Nation] alliance '''Digital Bible Library''' (DBL). The alliance brings together the United Bible Society, SIL/WBT, American Bible Society, Biblica and other Bible Agencies. Under the ETEN framework, Bible translations made publication ready in the DBL for access by approved End User Ministry Partners (EUMP) will be stored in USX format.

This page lists some of the more common file formats relevant to The SWORD Project, associated utilities, and other CrossWire projects.

CrossWire Bible Society respects copyright. As such, conversion of material that is under copyright without permission from the copyright holders is not supported by The SWORD Project.

SWORD modules

Other than the source code for the SWORD API, there is no documentation for the file format of a SWORD module. The intention is that the SWORD API (or the JSword implementation) is used directly or via other language bindings.

Our module file format is proprietary in the sense that we see no need to document it and certainly no need to stick to it. We change it when we need to. We therefore do not encourage direct interaction with it, but firmly recommend use of the API (either C++ or Java). This is the place where we seek stability and consistency.

The SWORD Project supports currently and actively the following markup for module creation: OSIS, TEI, ThML and plain text.

The SWORD Project Utilities

Precompiled versions of many of these programs are available in most Linux distributions, using the distribution's package installer.
For Windows, they can be found here.[1][2]

Module Creation Tools

It is recommended that Unicode text files used for module creation be encoded as UTF-8.[3]

  • imp2gbs – imports free-form General books in IMP format to SWORD format †
  • imp2ld – imports lexicons, dictionaries, and daily devotionals in IMP format to SWORD format †
  • imp2vs – imports Bibles and commentaries in IMP format to SWORD format †
  • vpl2mod – imports Bibles and commentaries in Verse-Per-Line format to SWORD format †
  • osis2mod – imports Bibles and commentaries in OSIS format to SWORD format †
  • tei2mod – imports lexicons, dictionaries in TEI format to SWORD format †
  • xml2gbs – imports free-form General books in OSIS or ThML format to SWORD format †

Diagnostic Tools

  • mod2imp – creates an IMP file[4] from an installed module †
  • emptyvss – exports a list of verses missing from the module (useful for testing modules during development) †

Legacy format conversion Tools

  • gbf2osis.pl – a PERL utility for converting GBF to OSIS †
  • step2vpl – export a STEP book in Verse-Per-Line (VPL) format †
  • thml2osis - converts ThML to OSIS format.

OSIS Utilities

  • vs2osisref – returns the osisRef of a given (text form) verse reference †
  • xml2gbs – imports free-form General books in OSIS or ThML format to SWORD format †

Miscellaneous

  • cipherraw – used to encipher SWORD modules †
  • diatheke – a basic CLI SWORD front-end †
  • mkfastmod – creates a search index for a module[5] †
  • mod2zmod – creates a compressed module from an installed module †

Notes on SWORD Tools

  1. ↑ If you have Xiphos installed in Windows, the Sword utilities are available in the Xiphos\bin folder.
  2. ↑ The latest binaries may be found here, though currently without cipherraw.exe
  3. ↑ EOLs should be either Unix style (LF) or Windows style (CRLF). Text files with Mac style EOLs (CR) may give rise to errors or other unexpected behaviour.
  4. ↑ The IMP file may contain a residue of XML markup
  5. ↑ Aside: To create a list of installed modules with descriptions, enter the following command, optionally redirecting stderr to a log file.
    mkfastmod /? 2>mkfastmod.log

Recommended Non-SWORD Utilities

  • uconv – a utility from ICU for converting between various character encodings, perform normalization, transliterate texts, etc. (It's similar to iconv, but much, much more powerful.) uconv.exe is part of the sword utilities
  • xmllint – a utility (part of the libxml2 distribution) for validating XML documents *

Formats for which CrossWire maintains converters

The SWORD Project uses primary source e-texts. These texts come in numerous formats. CrossWire maintains converters for a number of formats, described below. The converters may target other markup formats, e.g. TEI or OSIS, or may simply export binary data to text, as is the case with our STEP exporter. Specific discussion of each of the available converters is found elsewhere on this page.

USFM

Unified Standard Format Markers

This plain-text format is a common internal-use format within Bible translation agencies and Bible societies. It is the native format of ParaTExt. Paratext is used by more than 60% of all Bible translators world-wide. The current release is ParaTExt 8.0.

Though USFM 2.4 suffices for most Bibles, USFM 3.0 is now available and has several new features. The standard is open source and is maintained at ubsicap/usfm.

CrossWire now has a Python script called usfm2osis.py[1] which converts USFM to OSIS for subsequent import to SWORD's native format. See Converting SFM Bibles to OSIS.

USFM uses a separate file for each Bible book. USFM is also supported by the open-source program called Bibledit. There are examples of Bibles in USFM format available for download at [1]. These include the KJV, ASV, and WEB Bibles.

USFM is one of the formats that can be used by Go Bible Creator.

Note:

  1. ↑ This replaces our earlier Perl script usfm2osis.pl.

Other Utilities

These are not part of The SWORD Project, but may be useful. A link is given for each.

Go Bible utilities

  • Go Bible Creator - a Java SE program for converting either ThML or OSIS or USFM to Go Bible. It is being enhanced by SIL to be capable of converting source text in XHTML-TE format.
  • Go Bible Creator USFM Preprocessor – This is a tool to parse through and identify, correct and publish USFM file formats into a file format that can easily be put into the Go Bible mobile phone program.

ThML Utilities

  • CCEL Desktop - a program for viewing and developing CCEL books [2]
