[developers] consolidating LKB and [incr tsdb()] versions

[Stephan Oepen]

hi john,

many thanks, once more, for your continued work on the LKB, and likewise
for porting the core of [incr tsdb()] to additional lisp environments!

i feel we might want to try and reduce variation across different branches
of the code.  today, i know of the following three:

(0) lkb/trunk
(1) logon/lingo/lkb
(2) lkb/fos

i had originally created the LOGON branch of the code to (a) include some
bulky pieces (e.g. language models for realization ranking and associated
third-party software) that ann did not want in the LKB trunk and (b)
experiment with new or revised functionality (primarily working with the
ERG) without affecting the larger LKB community.

i have periodically merged back LOGON revisions into the trunk, so if we
were to look over #+:logon throughout the code now it should be a good
indicator of either (a) or (b).  as you activate some of that code in the
FOS branch now, in principle we should go back and review (b)-type
revisions for general, long-term use.  but i suspect that, at least among
the subscribers of the list, the LOGON version of the LKB has been used at
least as much as the isolated trunk ... hence i am not too worried.

since we branched FOS off the trunk a few years back, development in LOGON
has continued, whereas i believe no recent changes have been committed to
the LKB trunk.  therefore, i would be tempted to try and merge across these
two active LKB branches, and the possibly declare the current trunk a
frozen ‘dead end’?  would you have some time to jointly work on unification
of bug fixes and revisions this coming week?  inasmuch as the LOGON
environment is still used, i would like to incorporate your FOS
improvements.  and, likewise, i would want my changes (in [incr tsdb()] and
maybe MRS or EDS manipulation) exposed to the FOS users.

in terms of internal DELPH-IN responsibilities, the current LKB trunk used
to be packaged via what we call the LinGO builds (http://lingo.delph-in.net)
and the Ubuntu+LKB live CD (
https://wiki.ling.washington.edu/bin/view.cgi/Main/KnoppixLKB).  both are
maintained by UW, so i am not quite sure about the breadth of their user
base?  but i am wondering whether these UW builds could move to using the
FOS code in the foreseeable future (seeing as i am proposing to officially
call an end ?

best wishes, oe
