I know there are compound characters, but there are libraries around to handle them. 17:18:14 <baojie> Boris proposed to use Universal Character Set 17:18:58 <sandro> Boris: The problem is that in unicode, there are several ways to represent certain characters, eg accented characters. That's why they have Normal Forms, etc maximally composed, maximally decomposed, etc. 17:19:35 <sandro> Boris: I looked into how XML Schema handles this. Instead of Unicode, they use UCS. I think this is what we want. My proposal is to do exactly the same as XML Schema. 17:20:24 <sandro> Ivan: Okay. I'm a little bit uncertain about that.

If the languages are unified, then the situation is unclear to me.

So the question is whether implementors want these triples. 17:59:18 <JeffP> can someone answer my question? 17:59:35 <sandro> Alan: This suggests a blog post might go out, to OWL-R implementors, getting feedback. 17:59:36 <m_schnei> q- 17:59:41 <sandro> ack sandro 17:59:41 <Zakim> sandro, you wanted to mention Jena's approach 17:59:44 <IanH> q? 18:00:15 <msmith> there are many owl rule variants in Jena 18:00:21 <uli> Jeff, no 18:00:23 <alanr_> q? 18:00:32 <JeffP> thanks, uli 18:00:49 <sandro> Sandro: I remember Jena having a user-switch about such triples.

If you have two URIs, one URI for Cats, one for Dogs, ..... .... In OWL 2 punning ... 18:21:40 <IanH> q? 18:21:48 <alanr_> q? 18:21:56 <sandro> Peter: So in that view, RDF has no punning. So you're saying there is no punning. 18:22:18 <sandro> Ian: strawpoll about not making changes to spec. 18:22:35 <sandro> Alan: Let's not isolate folks. 18:22:58 <sandro> Ian: Just taking temperature 18:23:21 <sandro> Ian: It doesn't decide anything, and we've done it before. 18:24:27 <alanr_> q+ 18:24:33 <IanH> q? 18:24:36 <pfps> disallowed is object/data/annotation property *and* class/datatype punning, right 18:24:36 <sandro> Ian: Only punning disallowed is ObjectProperty/DataProperty right now. Other punning is allowed. 18:24:41 <Rinke> what would be disallowed beyond this, in alan's proposal? 18:24:50 <pfps> q+ 18:24:57 <alanr_> ack alanr 18:24:57 <sandro> Ian: I'd like to know what the other types of punning are and how they are interpeted. 18:24:58 <ivan> ack alanr_ 18:25:02 <IanH> q? 18:25:31 <sandro> q+ 18:25:34 <sandro> ack pfps 18:25:37 <alanr_> I will send an email, as suggested 18:25:38 <ivan> ack pfps 18:25:44 <sandro> ack sandro 18:25:58 <bmotik> A description of what kinds of punning are allowed is here: http://lists.w3.org/Archives/Public/public-owl-wg/2008Jul/0211.html 18:26:06 <bmotik> We've discussed this to the death already 18:26:43 <sandro> Sandro: Maybe some test cases would clarify it. 18:27:03 <sandro> STRAWPOLL: Should we close issue-114 without any changes to spec? 18:27:09 <pfps> +1 18:27:11 <uli> +1 18:27:12 <bmotik> +100000 18:27:12 <msmith> +1 18:27:13 <alanr_> -1 18:27:13 <MarkusK> +1 18:27:14 <bcuencagrau> +1 18:27:16 <JeffP> -0 (not decided yet) 18:27:24 <Rinke> +0.5 18:27:25 <sandro> sandro: -0 (not decided yet) 18:27:26 <m_schnei> 0 (not interested in this discussion anymore) 18:27:26 <Zhe> +0.5 (still wants to understand Alan's concerns) 18:27:26 <ivan> 0 18:27:31 <baojie> 0 (not clear about the issue) 18:27:31 <Achille> 0.5 18:27:44 <ewallace> +1 (but want Alan to clarify his concerns on email) 18:28:02 <ivan> q+ 18:28:13 <alanr_> q+ 18:28:20 <IanH> q? 18:28:25 <sandro> Ian: So, Alan, you have some work do to --- some explanation or test cases of what the concern is. 18:28:52 <IanH> q? 18:28:55 <uli> q+ 18:28:57 <IanH> ack ivan 18:28:59 <uli> q- 18:29:01 <sandro> Ivan: The mail that Boris just posted was helpful. Somewhere in the primer, maybe, there should be a list of punning situations. 18:29:22 <sandro> Ivan: The mail of Boris is just a table, which is technically fine, but as a user it's hard to follow. 18:29:57 <msmith> q+ 18:30:01 <msmith> q- 18:30:03 <ivan> ack alanr_ 18:30:04 <sandro> Alan: I will try to give a use case and try to clarify my previous proposal, and re-read that message and ask quesitons. I think if we had somthing of this form in the documentation, this would satisfy my concern, which is clarity. 18:30:07 <IanH> q? 18:30:26 <ewallace> sounds like test case(s) is what is needed 18:31:15 <alanr_> action: alan to have another try at proposal in the light of discussion with peter and come up with test cases 18:31:15 <trackbot> Created ACTION-202 - Have another try at proposal in the light of discussion with peter and come up with test cases [on Alan Ruttenberg - due 2008-08-27]. 18:30:27 <sandro> Ian: AOB? 18:31:13 <sandro> ADJOURN
