- JK: you can have various representations of the same content
- 13:51:01 [shadi]
- http://www.w3.org/TR/rdf-schema/#ch_alt
- 13:51:02 [carlosI]
- JK: byte, text, xml...
- 13:51:08 [carlosI]
- JK: how to model?
- 13:51:19 [carlosI]
- JK: could use rdf:Alt?
- 13:51:30 [shadi]
- "The first member of the container, i.e. the value of the rdf:_1 property, is the default choice."
- 13:52:25 [carlosI]
- SAZ: what should be the default representation may be another discussion
- 13:52:50 [carlosI]
- JK: maybe Bag too generally
- 13:53:07 [carlosI]
- SAZ: certainly not a rdf:Seq
- 13:53:53 [carlosI]
- SAZ: options are rdf:Alt rdf:Bag or no list at all
- 13:54:42 [carlosI]
- CV: prefer not list at all
- 13:55:02 [carlosI]
- SAZ: what is your reasoning to avoid using the semantic of a list
- 13:56:27 [carlosI]
- CI: the key question is they are equivalent not alternative
- 13:56:38 [carlosI]
- CI: you can choose one or several
- 13:56:51 [carlosI]
- CI: musn“t be forced to choose just one
- 13:57:59 [carlosI]
- JK: can create a new object, a sort of equivalent container
- 13:58:23 [carlosI]
- SAZ: not sure about the value
- 13:58:47 [carlosI]
- SAZ: let's keep it for now and put an editorial's note asking for feedback
- 13:59:34 [carlosI]
- JK: is your proposal havin multiple bodies properties?
- 13:59:37 [carlosI]
- SAZ: yes
- 14:00:45 [carlosI]
- SAZ: looks good, just a little bit of clean up and wait for the Content

- 14:03:39 [carlosI]
- JK: references for files, not namespaces
- 14:03:47 [carlosI]
- JK: rdf, not rdfs
- 14:05:59 [shadi]
- zakim, take up next
- 14:05:59 [Zakim]
- agendum 3. "Draft RDFS schema for Pointer Methods" taken up [from shadi]
- 14:06:06 [shadi]
- http://pruebas.fundacionctic.org/uaw/Pointers_DRAFT.rdf
- 14:06:38 [shadi]
- scribe: shadi
- 14:07:36 [shadi]
- CI: subclass rdf:Bag and reuse it for specific purpose
- 14:07:50 [shadi]
- ...to use the rdf:li items
- 14:08:01 [shadi]
- JK: think that should be legal, yes
- 14:08:22 [shadi]
- CI: easier to understand this approach, and also more logic
- 14:08:33 [shadi]
- ...have containers with groups of pointers
- 14:08:53 [shadi]
- ...we can think about Sequences or Alternative lists too
- 14:09:24 [shadi]
- JK: problem with RDF lists is that you can't describe the types of object in the lists
- 14:09:38 [shadi]
- ...it would be legal to add *anything* into the group
- 14:10:07 [shadi]
- CI: can't subclass the rdf:li property
- 14:10:25 [shadi]
- ...to change the range of the property?
- 14:11:37 [shadi]
- SAZ: did you try running this code through some of the RDF validators and parsers?
- 14:12:07 [shadi]
- CI: it is valid, haven't tried subclassing the rdf:li property
- 14:12:34 [JohannesK]
- <http://www.w3.org/TR/rdf-schema/#ch_container>
- 14:12:45 [shadi]
- JK: there is no real rdf:li, it is a variable property
- 14:13:13 [JohannesK]
- <http://www.w3.org/TR/rdf-schema/#ch_containermembershipproperty>
- 14:14:40 [JohannesK]
- <http://www.w3.org/TR/rdf-schema/#ch_member>
- 14:15:15 [shadi]
- SAZ: the RDF validator focuses primarily on the schema and validity, others try to explore the semantics
- 14:15:46 [shadi]
- ...mainly OWL validators, they spot important issues such as if certain restrictions can not be met
- 14:16:08 [shadi]
- ...there is a mail about some of these parsers somewhere on the mailing list
- 14:17:24 [shadi]
- JK: no range for the reference property?
- 14:17:35 [shadi]
- SAZ: no range, it could be anything
- 14:20:32 [shadi]
- [discussion if should have a range, and what it would be]
- 14:23:08 [shadi]
- action: CarlosI to finalize draft RDFS (check with validators/parsers), and send comments/questions to the mailing loist
- 14:23:57 [shadi]
- action: all to review draft RDFS proposal by CarlosI and send comments to the list
- 14:24:43 [shadi]
- CI: should we make equivalent pointer class a subclass of single pointer?
- 14:25:05 [shadi]
- ...all the equivalents point to the same place
- 14:26:05 [Zakim]
- -CarlosV
- 14:26:09 [shadi]
- SAZ: sound good, would be easier to see in the hierarchy model (see thread on the mailing list)
- 14:26:44 [shadi]
- JK: reference properties could be different between the container and the pointers
- 14:27:01 [shadi]
- CI: we have the same problem in many other instances
- 14:27:37 [shadi]
- JK: we removed it from the equivalent pointer class to avoid this problem, we are reintroducing it by using single pointer
- 14:27:51 [shadi]
- CI: we have the same problem in compound pointer and elsewhere
- 14:28:38 [shadi]
- JK: agree, we also agreed that it may sometimes make sense to have different references (although the pointers are equivalent)
- 14:28:47 [shadi]
- ...however, what is the logic in this case?
- 14:29:25 [shadi]
- CI: we have to think more about the reference and see how we can provde more guidance
- 14:31:08 [shadi]
- zakim, take up next
- 14:31:08 [Zakim]
- agendum 4. "Next Meeting" taken up [from shadi]
