Re: [search-ws-comment] Relative/Variable Dates in CQL

["Ray Denenberg, Library of Congress" <rden@loc.gov>]

Hello Tim -

First let me address the "where to have this discussion" question.  I have 
had this conversation before with OASIS officials, about the purpose of this 
listserv -  is it a discussion list or simply a place to register comments - 
and I haven't really gotten a satisfactory answer, because, I think it is 
both.  There are two other possibilities besides here.

First, if you are or your company is an OASIS member (i.e. either you an 
individual member  or your company a corporate member) then you can join the 
committee (as an observer if you prefer, or an active member) and 
participate directly in the discussion on the committee listserv.

Another possibility, if this conversation is about SRU/CQL in general and 
not specific to the version 2.0 in development, then the appropriate place 
for this discussion would be on the SRU listserv.  See 
http://www.loc.gov/standards/sru/community/listserv.html

And I think your question is more along the general lines.  We can discuss 
this here if you prefer but I suggest that you subscribe to the SRU list and 
post this question and I think it will generate alot of discussion.   If you 
do, we will register the result of that discussion here, since we are 
obligated to resolve questions and issues posted here.

Thanks.

--Ray
