We have a candidate here who is speaking during part of the telecon time later today so i will miss some of the meeting. Thus, just in case the fragments discussion is not when i am on, i wanted to post the things i care most about with respect to fragments. 1 - i would like to see backwards compatibility with OWL-Lite. 2 - i know of a number of users who would like to use some fragment(s) of OWL and i think it is important to have at least one (and hopefully not 10s of) option(s) for useful fragment(s). 2a - i would like to have at least one fragment have first class status and thus it seems to me that at least one is rec track. 3 - i know of the most need for something like the fragment jeremy and jim and asking for and thus, this seems more compelling (although i admit to not really knowing how to quantify this notion well). deborah Ian Horrocks wrote: > > In an effort to get us thinking and to structure our discussion we > came up with the following list of questions/topics (see > http://www.w3.org/2007/OWL/wiki/Teleconference.2008.01.30/Discussion). > Although we don't expect to make any firm decisions, we do hope to > reach agreement on some general directions. > > Note that as this is a large and as yet relatively little discussed > topic we have allowed 45 minutes.
