DM,
Cool! RST (Russian Synodial Translation) is another you might want to the list for alternate versification, the Psalms especially.
Thanks!
Steve

Subject: [jsword-devel] Alternate Versification
SWORD is adding the ability to have other versifications (v11n) than
the hard-coded KJV v11n. We need to add this to JSword, too.
There are some of ways that one v11n can differ from another:
1) Additional books - E.g. Apocrypha/Deuterocanonical
2) Different order of books - E.g. Hebrew Tanakh.
3) Different "long" names for the books. E.g. 1-4 Kings.
4) Different number of chapters in a book. E.g. Some only have 3
chapters in Malachi, with all of KJV's chapter 4 at the end.
5) Different number of verses in a chapter. E.g. Many have 3 John 1:15
6) Different numbering of the verses. E.g. The titles in the Psalms
come before verse 1 in the KJV, but are verse 1 in the KJV.
There may be others.
The issue of mapping (#6) is not being addressed at this time.
In the module's conf, a module will have a new entry
Versification=KJV
which if absent, will default to the KJV.
New v11n include:
KJVA
Leningrad
Tanakh
NRSV
NRSVA
Some others that may be added before too long:
Luther
Vulgate
Original - a combination of the Tanakh, Apocrypha (possibly from the
LXX) and GNT.

Enough of the preamble. We need to change JSword and it will break all
existing programs: Bible Desktop, Alkitab, FireBible, and ones we
haven't been told about.
I would like it if we can do this with a minimum of problems.
I have been following the development of Lucene and I like their
model. To do a break like this, they:
1) Add new classes and/or methods.
2) Mark affected classes and methods as deprecated, pointing each
deprecation to the new code.
After a release containing both the new code and the deprecated code,
they have another release that removes those deprecations.
Would this work for us?
Next question is that of design. Most of it will be in
o.c.jsword.versification:
1) Each of the new v11n systems is hard-coded into the SWORD engine
for maximal lookup speed. There is no startup cost, but it increases
the core size of the program. We can do something similar, or we can
put the definition into resource files and read them in on first need.
I'm leaning to the latter.
2) There is a strong notion of a book having a fixed ordinal value.
Currently, there is no accommodation for extra books.
This affects most of the classes in o.c.j.versification.
2.1) OSISNames has an ordered list of books and does not include the
apocrypha. There are conversions to and from an OSIS name and a book
number. I think we can keep this with the addition of the book numbers.
2.2) BookNames is a localized representation of a book number and has
hard-coded integer values for Gen-Rev (1..66). I think these numbers
need to move to OSISNames, perhaps as an enumeration OSISBookNumber.
And BookNames should take an OSIS name or an OSISBookNumber to do the
lookup.
2.3) SectionNames likewise would be change to take an OSIS name or an
OSISBookNumber to do the lookup. For the purposes of Advanced Search
in BibleDesktop, there would need to be some kind of getRange(int
section) that would need to be added. I think it might be good to
change this to an enumeration, too.)
2.4) BibleInfo is the most problematic as it really is KJVBibleInfo
and now we need a BibleInfo for each v11n scheme. I think we need a
VersificationManager that given a v11n name, it will return a
BibleInfo specific to that v11n. It too is indexed by book number, but
in this case, it will need to be the ordinal position of the book in
that system and not the OSISBookNumber. It might be good to add an
iterator of the books in BibleInfo that returns OSISBookNumber.
2.5) BookName knows it's book number. Hmm.
The whole notion of a book having an integer value might cause non-
obvious breakages if we change it's semantic. I'm inclined to break
the notion of book numbers entirely so that all using code needs to
change. But still, I'd like it to be as simple a migration as possible.
I'd really like input.
Together in Christ,
DM
