colleagues,
two weeks ago i had inadvertently introduced a bug in the MRS creation
from grammar-internal feature structure, resulting in events being mis-
construed as MRS variables of type `i'. the bug only affected the old
version of the ERG, or other grammars (and only the SVN `trunk'). dan
and i were busy with a near-complete new release of the ERG, hence did
not notice this issue (until ann found and repaired it). my apologies
for the hick-up!
the forthcoming ERG version uses the VPM also for mapping of variable
types, i.e. the family of parameters *event-type*, *ref_ind-type*, et
al. becomes unnecessary. i have updated the VPM documentation:
http://wiki.delph-in.net/moin/RmrsVpm
i would recommend that both JaCY and GG extend their VPMs to make use
of this extended functionality. eventually, i would try to deprecate
the traditional mechanism, i.e. *event-type* et al.
another `new' facility is more or less documented on the wiki now:
http://wiki.delph-in.net/moin/ReppTop
REPP is still work in progress, but used centrally in the forthcoming
ERG release. i believe only GG has pre-processor rules today, and in
the long run i hope that REPP (plus chart mapping) can replace FSPP.
i will announce these and other developments more widely once we have
completed the ERG release, in a sense our `model solution' for putting
to use all the new toys :-). but, if nothing else, please update your
LOGON tree to obtain the MRS bug fix mentioned initially.
best wishes - oe
