Jeni proposes RDFa to also allow these elements 14:09:22 q? 14:09:26 ... consequently HTML+RDFa would include parts of the HTML5 content module, which is tricky 14:09:28 ack manu1 14:09:28 manu1, you wanted to comment on datetime issue 14:10:06 q+ 14:10:11 manu: there is a chance that time element is going to be replaced by data elements. Data contains machine readable values about content 14:10:21 ack lindstream 14:10:30 ivan: hence, it is an open issue and we should leave it for now 14:10:55 q+ to note how we follow HTML5 via HTML+RDFa 14:11:13 lindstream: there is a problem with versioning issues 14:11:29 \me Nicklas I missed your point. Could you repeat it in log? 14:11:52 q- 14:12:21 my point was that html5 is a "living spec", which supposedly won't have versioning. So the rdfa spec, having versions, might have trouble "keeping up" 14:12:41 np :) 14:14:04 q? 14:14:12 ivan: HTML allows the use of meta only if it contains microdata content. This is a bit strange. 14:14:42 ISSUE: Determine if RDFa should normatively state that and elements are supported in flow content. 14:14:42 Created ISSUE-104 - Determine if RDFa should normatively state that and elements are supported in flow content. ; please complete additional details at http://www.w3.org/2010/02/rdfa/track/issues/104/edit . 14:15:07 ivan: Next issue is about build in prefixes. 14:15:18 ... RDFa has such a mechanism 14:15:45 ... Next issue is about the itemref functionality 14:15:47 ISSUE: Should RDFa support something like Microdata's @itemref attribute. 14:15:47 Created ISSUE-105 - Should RDFa support something like Microdata's @itemref attribute. ; please complete additional details at http://www.w3.org/2010/02/rdfa/track/issues/105/edit . 14:16:12 ISSUE: Should RDFa support the creation of ordered lists? 14:16:12 Created ISSUE-106 - Should RDFa support the creation of ordered lists? ; please complete additional details at http://www.w3.org/2010/02/rdfa/track/issues/106/edit . 14:16:15 ivan: There is an issue about the creation of ordered lists in RDFa 14:17:18 ivan: The next issue for us is about using the src attribute 14:17:54 ISSUE: Determine if @src attribute should be viewed in the object position instead of the subject position. 14:17:55 Created ISSUE-107 - Determine if @src attribute should be viewed in the object position instead of the subject position. ; please complete additional details at http://www.w3.org/2010/02/rdfa/track/issues/107/edit . 14:17:56 manu: the concern about this is backward compatability. 14:18:19 @src is often a problem for example markup, one of the things I noted that people often get wrong. 14:18:58 ivan: Jeni mentions link relations, which relates to the use of terms in RDFa1.1 14:19:22 .. we might revise which terms are relevant or not 14:19:39 ISSUE: Refine/deprecate Link relations for the RDFa 1.1 Default Profile. 14:19:40 q+ 14:19:40 Created ISSUE-108 - Refine/deprecate Link relations for the RDFa 1.1 Default Profile. ; please complete additional details at http://www.w3.org/2010/02/rdfa/track/issues/108/edit . 14:19:51 ack lindstream 14:20:06 ... at the moment the RDFa HTML default profile still contains all tokens, which we should look at again 14:20:16 q+ to say we've discussed this before. 14:20:44 lindstream: Jeni's problem was about the implied subject, when using these link relations. 14:20:53 ack manu1 14:20:53 manu1, you wanted to say we've discussed this before. 14:20:56 Remember that ARIA cares about some of those relationships. 14:21:04 q+ 14:21:08 ivan: someone should lookup the list of necessary tokens in RDFa 14:21:41 Zakim, unmute me 14:21:41 bergie should no longer be muted 14:21:42 ack bergie 14:21:53 manu: link relaitonships concern the HTML integration and should not be defined in RDFa core 14:21:55 one example raising the subject issue is: rel="stylesheet alternate" 14:22:57 bergie: We should spend more explanations on these tokens and their relation to subjects 14:23:36 Zakim, mute me 14:23:36 bergie should now be muted 14:23:47 for the record: one way out of this "mess" *might* be the idea of letting @property capture @href/@resource if present... 14:23:53 ivan: these are the issues we can extract from Jeni's blog 14:24:07 manu: That is four new issues. 14:24:26 manu: Any other concerns about Jeni' 14:24:31 Topic: ISSUE-103: preserve @vocab declarations 14:24:39 .. writeup? 14:24:39 http://www.w3.org/2010/02/rdfa/track/issues/103 14:24:44 ISSUE-103? 14:24:44 ISSUE-103 -- Should RDFa Processors preserve @vocab declarations in the default graph? -- open 14:24:44 http://www.w3.org/2010/02/rdfa/track/issues/103 14:25:34 rdfa:has-vocab 14:25:44 .. or rdfa:usesVocab ? 14:25:46 ivan: first thing is that the term i used in the mail was not good -- rdfa:hasVocab 14:26:02 a rdfa:source ; 14:26:07 q+ 14:26:41 provenance :-) 14:27:01 if used, it should be rdfa:Source (uppercase 'S') 14:27:09 ivan: other thing is that a link from triples to the original source is missing. Some people complained about that. 14:27:19 ack lindstream 14:28:58 So, the current proposal seems to be: rdfa:hasVocabulary . 14:29:05 q+ to discuss an issue 14:29:54 np; short version: I'm beginning to agree with Ivan's suggestion 14:30:15 q+ 14:30:22 ack manu1 14:30:22 manu1, you wanted to discuss an issue 14:30:44 ack ivan 14:31:21 foo:bar 14:31:28 vocab1 vocab2 14:31:42 q+ 14:31:47 vocab1:bar or vocab2:bar :) 14:31:47 ack gkellogg 14:32:14 q+ 14:32:42 q+ to say ask why the rdfs claim would matter? 14:32:53 ack lindstream 14:34:07 vocab1 { dc:title rdfs:subPropertyOf rdfs:label } vocab2 { dc:title rdfs:subPropertyOf something else} 14:34:29 … expands all use of dc:title within document 14:34:50 q+ 14:34:52 ack ShaneM 14:34:52 ShaneM, you wanted to say ask why the rdfs claim would matter? 14:35:48 Shane: initially, rdfs expansion was not in scope of the RDFa processor? 14:36:04 Benjamin: and it still is not 14:36:25 ack ivan 14:36:29 RDFS uses multiple inheritance FTW ;) 14:37:14 +1 14:37:47 manu: finally, there is no issue with the current proposal 14:38:57 ivan: let's accept the proposal 14:39:00 Also generate <> a rdfa:Source when @vocab encountered? 14:39:12 +1 uses 14:39:30 PROPOSAL: Generate a triple in the default graph when the @vocab attribute is processed: rdfa:usesVocabulary . 14:39:34 +1 14:39:35 +1 14:39:37 +1 14:39:37 +1 14:39:37 +1 14:39:39 +1 14:39:39 +1 14:39:40 +1 14:39:41 +1 14:39:54 RESOLVED: Generate a triple in the default graph when the @vocab attribute is processed: rdfa:usesVocabulary . 14:39:55 and +1 to Gregg's "also rdfa:Source" 14:40:13 a rdfa:Source . 14:40:47 manu: Why is the triple useful? 14:40:59 You need to know provenance. I agree 14:41:12 ivan: At the moment there is no way to make preserve any provenance information 14:41:25 Zakim, unmute me 14:41:25 MacTed should no longer be muted 14:41:49 .. in terms of indexing, the index should contain links to originating sources 14:42:01 rdfa:Source will mean e.g. "this resource is data markup using RDFa" 14:42:38 MacTed: That's also how we do it in our product. 14:43:05 q+ 14:43:29 ack lindstream 14:44:25 a look at an example... http://linkeddata.uriburner.com/about/html/http://linkeddata.uriburner.com/about/id/entity/http/cprtheory.referata.com/wiki/Main_Page 14:44:35 manu: it is not related to the vocab attribute 14:45:54 MacTed: It's about this is document the processor extracted RDFa from 14:46:15 btw, rdfa:Source should be a subClassOf (e.g.) foaf:Document 14:46:23 ShaneM: It is a provenance concern 14:46:57 MacTed: The minimum that I need is, this is document were I got the data from. 14:47:31 .. *if* we got data from it? (Even just from rel stylesheet?) 14:47:37 manu: That means in every default graph of an RDFa processor a triple shuld exist that says where the data comes from 14:48:03 manu: But if we merge two graphs, such triples become useless 14:48:30 MacTed: Of course you have to add graph identifiers 14:48:32 q+ 14:48:37 ack lindstream 14:50:26 quads are beyond the scope of this issue... 14:52:17 foaf:primaryTopic 14:52:22 .. are we at risk of conflating documents and graphs here? 14:52:35 14:53:02 q+ 14:53:54 foaf:primaryTopic 14:53:58 Then we'd need to make assertions about graphs, which requires quads 14:54:13 <> foaf:primaryTopic 14:54:15 q+ 14:55:00 ack lindstream 14:55:40 Zakim, unmute me 14:55:40 bergie should no longer be muted 14:55:48 ack bergie 14:55:49 I'm also in Provenance WG... :-) 14:56:15 (which call starts in 5 minutes) 14:56:27 Bless you. someone has to do it. 14:57:10 http://dvcs.w3.org/hg/prov/raw-file/default/model/ProvenanceModel.html 14:57:10 <> describes 14:57:39 Only different if document has html>head>base? 14:59:05 ... while graph identifiers enable us to "have turtles all the way down", we're within the RDFa "turtle" and should stay here. 15:00:17 q+ 15:00:17 so, my proposal was not to set a source URI for a given graph, since the graph itself doesn't have an identifier 15:00:33 but instead to just say "this subject has data coming from this RDFa document" 15:00:42 I agree with Ted that this is a significant terminology issue. 15:00:45 Zakim, unmute me 15:00:46 bergie was not muted, bergie 15:01:02 I also agree that we should have a way to reference our 'graph' in notation. 15:01:09 Zakim, mute me 15:01:11 bergie should now be muted 15:01:23 +1 on "output graph".

We don't have a mechansim to name the output graph 15:02:15 +1 lindstream, on both points 15:03:17 manu: This is end of the call. We need to define additional issues 15:03:36 ISSUE: Should RDFa Processor output a triple for the source of a graph? 15:03:36 Created ISSUE-110 - Should RDFa Processor output a triple for the source of a graph? ; please complete additional details at http://www.w3.org/2010/02/rdfa/track/issues/110/edit . 15:03:57 The Definitive Guide to Drupal 7 book was published by Apress: http://definitivedrupal.org/ - one of the chapters I contributed is on Drupal and the Semantic Web, Linked Data and RDFa 1.0 (namespaces, prefixes, CURIEs, etc...) 15:05:45 scor: congrats about the book! hopefully the Drupal 8 edition will be able to talk about VIE as well :-) 15:06:19 -Knud 15:06:20 bergie: thanks. sure!
