All the existing stuff can be claimed as implementations of 15:24:28 ...SKOS. Also tools that are there already. A new namespace means we have to wait for implementation 15:24:48 ...plus there will be a period of time while people migrate, which could take years. 15:25:11 ...Realistically means tool developrs have to maintain multiple implemetations. 15:25:31 ...Bottom line is that there is little gain from a new namespace and a cost involved. 15:25:50 ...Assumed that the LC would use the new namespace, but marked as "at risk". 15:25:56 ...Would appreciate comments. 15:26:17 Guus: I see objections, but no need to reopen the issue. 15:26:31 Alistair: Under what circumstances would we need to reopen the issue? 15:26:41 Guus: if we reopen, we can't go to LC. 15:27:56 ...saw one comment that the change in semantics requires a new namespace (Simon Spero) 15:28:29 Alistair: unsure whether to take this comment. There may be some misunderstanding of transitive. 15:28:37 Guus: Happy to mark it as "at risk". 15:29:09 Alistair; Ok 15:29:27 Antoine: Would like to discuss ISSUE 83. Semantics of concept scheme containment 15:29:47 ...some problems with the implementation. Alistair proposes a new property to capture the 15:29:51 ...semantics. 15:29:59 Guus: This seems rather drastic at this point. 15:30:02 http://lists.w3.org/Archives/Public/public-swd-wg/2008Jul/0036.html 15:30:09 -> start of the thread 15:30:15 Alistair: I think this is less drastic. 15:30:47 http://lists.w3.org/Archives/Public/public-swd-wg/2008May/0068.html 15:31:11 -Margherita 15:31:13 ex:cs skos:hasTopConcept ex:c. 15:31:14 Alistair: Email above contains resolution to the issues. Email merely states an entailment. 15:31:15 entails the graph: 15:31:16 ex:c skos:inScheme ex:cs 15:31:40 ... want to follow this entailment, but resolution doesn't state how we go about making this happen. 15:31:58 ...Spent some time thinking and what we're trying to say is that skos:hasTopConcept has an inverse which is a 15:32:07 ...subproperty of skos:inScheme 15:32:31 ...Most obvious way to express this is to name the inverse and then state it explicitly. 15:32:47 ...if we don't name it then it requires an anonymous property. This 15:33:04 ...could be a potential problem. Would appreciate input from Jeremy. 15:33:29 Jeremy: OWL2 may be about to allow anonymous properties. One issue is that it pushes 15:33:52 ...you out of OWL DL. Can't use the anonymous property in a triple (not as predicate). 15:34:07 ...so in terms of describing the relationships, there's nothing particularly wrong, but implementations 15:34:27 ...may find it difficult. Procedurally, putting in an anonymous property may cause trouble, 15:34:43 ...but a new property might also cause problems. 15:34:55 Guus: But other things are not stated in the data model. 15:35:09 Alistair: There are two constraints expressed as prose, but there is no way to do that in 15:35:38 ...RDF or OWL. Here, it *is* possible to do it. 15:36:02 ...Would avoid complication of anonymous properties. 15:36:21 Guus: Only require inverse of hasTopConcept or inScheme. 15:36:30 ...topConceptOf would do the trick. 15:36:40 Alistair: Called it topConceptInScheme in Ref. 15:36:46 Guus: awful name! 15:37:01 Alistair: Subjective view. Not really worried about the naming. 15:37:33 Jeremy: is the intention to document the relationship within OWL. Could one include this in 15:37:44 ...a separate file with a seeAlso. 15:37:56 Alistair: If we can do it without jumping through hoops, why not do it? 15:38:30 Guus: Surprised that other constraints can be expressed in RDF. 15:38:48 Alistair: All but two current. Would be three with this one. 15:38:58 Guus: WHat's the problem with three rather than two? 15:39:07 Alistair: For this one, we could do it. 15:39:20 Guus: But only at the cost of new vocabulary. 15:39:41 Alistair: But non-standard semantics is also costly. 15:40:02 Antoine: Can't see why my axiom is not valid OWL 15:40:14 Alistair: Entailments that follow are not valid RDF. 15:40:38 Jeremy: There is a bug with RDF (ter Horst). Significant problems and adding an anonymous 15:40:54 ...property would exercise that bug. Would advise against it. 15:41:12 Antoine: That's the argument I was looking for. 15:41:28 Antoine: Also assume a bug in the OWL specification then. 15:41:44 Jeremy: There is a need for a bug fix. But will not be done any time soon. 15:41:51 Guus: We're not going there. 15:42:14 Jeremy: Cost of new predicate vs. non-standard. New predicate is cheaper. 15:42:55 ...preference would be to say nothing. 15:43:26 Guus: small cost with a small group. 15:43:58 Sean: preference for new predicate. 15:44:14 Guus: Suggest that Reference Editors make a proposal for this. 15:44:32 ...Will reopen ISSUE 83, but expect a proposal to close with a new property. 15:44:41 Alistair: Do we need to open the issue> 15:44:50 Guus: yes, need documented rationale. 15:45:07 ...alternative is to open new issue and immediately propose closing it. 15:45:13 ...That might be better. 15:45:24 ...for me topConceptOf would be an appropriate name. 15:45:49 ..Propose a new issue which is then closed. 15:46:11 ACTION: Alistair to open issue relating to topConceptOf and propose a resolution. 15:46:24 Guus: Any more w.r.t content? 15:46:29 Antoine: happy 15:47:06 Guus: Margherita reviewed, but reviewed the old draft. 15:47:13 ...chance for a new draft next week? 15:47:34 Alistair: Think so. Resolutions to things are done. Need to mark at rsik and some editorial stuff. 15:47:59 Guus: Earliest possible for LC decision is August 19th. 15:48:30 ...problem for Guus as on holiday. Could review but only in next two days. 15:48:39 Alistair: Have to finish this week. 15:48:56 Guus: Could do it if it's there by Friday. 15:49:17 Alistair: Could provide a link which will be pretty much the version we publish. 15:49:41 Guus: Can expect cmments by the 12th, one week for discussion and a decision about LC 15:49:46 ...on the 19th. 15:50:28 ...would be preferable if at the same point we have a primer draft consistent with the Reference. 15:50:46 Antoine: Feasible apart from action on co-ordination. 15:51:11 ...Version of the primer for the 19th? 15:51:29 Guus: Would also like to take a decision about publishing primer on 19th. 15:51:44 ...agenda item for next week will be scheduling. 15:52:22 ...also need to discuss LC period given that 15:52:33 ...publishing will take a few days. 5-6 week period is appropriate. 15:53:17 ...end September/beginning October. 15:53:34 Sean: some traffic on the list about broader/broaderTransitive. 15:53:45 Guus: no new arguments there. No real evidence to reopen this. 15:54:09 Alistair: i'd agree. Concerned about how many people misunderstand this. 15:54:20 ...not a technical problem, but perhaps some confusion with names. 15:54:33 ...its a shame that people are misunderstanding this. 15:54:56 Sean: Question of education rather than technical details. 15:55:09 Antoine: Whatever the names, the pattern will be the same, and that's 15:55:13 ...hard for people to get. 15:55:25 Guus: Will pay attention to this. 15:55:46 Jeremy: Is a simple example more accessible? Parent/Ancestor etc? 15:56:03 JeremyCarroll has joined #swd 15:56:09 Sean: is the reference an appropriate place for this? 15:56:21 Antoine: Could put some drawings in the primer. 15:56:37 Alistair: Antoine's slide at the SKOS event was very clear. 15:56:59 Antoine: Animated. 15:57:06 Guus; Could make snapshots. 15:57:31 Guus: Parent/ancestor is already a long way towards this. 15:57:52 Topic: Vocabulary Management 15:57:57 Guus: nobody here 15:58:02 Topic: RDFa 15:58:05 Guus: nobody here 15:58:10 -> http://www.iskouk.org/SKOS_July2008.htm ISKO event with link to antoine's slides 15:58:15 Topic: Recipes 15:58:18 q+ to mention need for RDFa reviewers 15:58:39 q- 15:59:00 q- Jeremy 15:59:03 ACTION: Ben to prepare draft implementation report for RDFa (with assistance from Michael) [recorded in http://www.w3.org/2008/01/22-swd-minutes.html#action14] 15:59:05 --continues 15:59:21 Guus: Recipes? 15:59:35 Diego: Document is ready to be published.
