Introduction

Alternative versifications mean ultimately to allow Bible texts with arbitrary canon or versification schemes to coexist peacefully on the same SWORD installation and (ultimately) to map cleanly between each other via cross references or parallel display.

There are technically 2 routes to support this under development:

1. ripping out the hardcoded KJV canon.h offsets and replacing them with VerseMgr, which allows registration of canon.h-like v11n systems.
2. genbook Bibles

Both have been under development and 2 requires 1.

Overview

Up until 1.5.11 the canon and the versification was hard coded into the engine in form of the file canon.h which offered book names and chapter + verse offsets to the engine. The new approach is that

1. Each Bible module will carry a conf entry about its versification (unless KJV) from an approved list of versifications
2. the engine will have for each major canon and versification variety a new header file similar to the previous canon.h
3. On system start the engine will load for each open KJV-divergent module the relevant data presented in the relevant canon_{Versification].h into a table held in memory.
4. Subsequently the relevant module will be accessible via the usual methods - which have not changed from 1.5.11
5. What does not work anymore is to assume that a book or chapter has a set (fixed) number of verses. Instead 1.5.12 introduces new methods VerseKey::getChapterMax() and VerseKey::getVerseMax() providing you for a given module with the relevant information and replacing VerseKey::books[testament][book].chapmax and versemax members.
6. Similarly VerseKey::getBookName() and VerseKey::getBookAbbrev() replace the previous const char *name; and const char *prefAbbrev; respectively.
7. At a later stage (1.5.13) the engine will allow for genBook bibles to automagically create arbitrary versification tables on the fly.
8. the final step (in 1.5.13 or 1.5.14) will be to allow mappings between versification schemes to allow cross referencing and parallel display of identical passages.

How to create Modules with alternative versifications

1. Set the relevant entries in the configuration file Configuration file
2. If your module uses a versification or canon not yet present in SWORD you might have to create a canon header file. Sword tools contains relevant scripts. Please be aware that we will not hard code every versification nder the sun but only select and important ones. If your scheme is not one of those you will need to go down the route of a GenBook bible. Discuss on Sword-devel what you are planning to do and you will get appropriate advice.
3. The importers will work as usual. You'll specify a versification for the text to the import utility (imp2vs or osis2mod). It will pass the v11n value to the SWText constructor, which will instruct it to use the specified v11n.
4. Append will also work as usual. Append pertains to whether a text is overwritten or appended to, so its use can affect the stored order of verses, but won't affect where the engine thinks they belong for access/display purposes.
5. Each v11n will specify a book order, so different traditions that vary with respect to book order would have to be represented by different v11n definitions.

Modules requiring alternate versification

• Ohienko Ukrainian translation.
  The existing module had discarded the original Ukrainian verse numbers. ua4ever has recently made an OSIS file in the KJV order, but with the original Ukrainian verse references in parentheses. Download RAR file from [1]. For related discussions, see [2]. Registration and login is required.
