15:25:29 <seanb>    http://www.w3.org/2007/10/23-swd-minutes.html
15:25:36 <seanb> RESOLVED
15:25:53 <seanb> Topic: SWD review of "Cool URIs for the Semantic Web"
15:26:01 <seanb> Guus: Nothing to track here for this telecon
15:26:10 <seanb> ...comments have gone to SWEO group. For the moment,
15:26:15 <seanb> ...we can be silent on this.
15:26:27 <seanb> Ralph: We're done with that task. Can remove from agenda
15:26:35 <seanb> Topic: SKOS
15:27:24 <Ralph> http://www.w3.org/2007/10/23-swd-minutes.html#action14
15:27:32 <Antoine> http://lists.w3.org/Archives/Public/public-swd-wg/2007Oct/0139.html
15:28:07 <seanb> Guus: The minutes capture the interpretation.
15:28:29 <aliman> s/transitive/functional/
15:29:11 <seanb> Ralph: We're happy that it's not functional?
15:29:21 <seanb> Guus: Yes, there may be examples where it's not.
15:29:38 <seanb> Ralph: Context of that discussion were w.r.t the semantics of inScheme
15:29:59 <seanb> ...recently had a discussion in a separate group about semantics of isDefinedBy
15:30:09 <seanb> ...would be nice to have even stronger semantics for isDefinedBy
15:30:57 <aliman> I remember TimBL saying something like that about isDefinedBy in the context of the tabulator
15:31:12 <seanb> ...is this group interested in going further with this?
15:31:26 <seanb> Guus: Can't do this -- we'd need to define our own property
15:32:11 <aliman> TimBL wanted to avoid having to make unecessary HTTP requests
15:32:14 <seanb> Ralph: WOuld be acceptable for this group to suggest what the semantics of
15:32:20 <seanb> ...isDefinedBy are.
15:32:27 <seanb> ...if they wished to
15:33:30 <aliman> +1 possibly useful interpretation, especially for large vocabularies -- typical for SKOS
15:33:38 <seanb> Guus: If this isn't inappropriate, it might be useful
15:34:05 <seanb> ACTION: Ralph to reconstruct proposal for semantics of isDefinedBy
15:34:27 <seanb> Alistair: Two separate issues
15:35:05 <seanb> ...stronger semantics for isDefinedBy could be useful to reduce HTTP call overhead
15:35:22 <seanb> ...also whether or not we think of inScheme as functional. Is it reasonable to think of concepts in 
15:35:46 <seanb> ...more that one scheme. If so, forks discussion as inScheme and isDefinedBy go in different directions
15:36:37 <seanb> Guus: propose we put this on the agenda once we have Ralph's message
15:36:50 <seanb> Jon: Disagree with some of the decisions we're making. 
15:37:05 <seanb> ...But don't have supporting evidence, but things "feel wrong". 
15:37:25 <seanb> Guus: We haven't actually made decisions yet. 
15:37:47 <seanb> Alistair: Jon refers to e.g. decision to deprecate inScheme and use isDefinedBY instead
15:37:49 <seanb> Jon: Yes
15:38:14 <seanb> Alistair: Justification is that copncepts get used in different schemes. 
15:38:31 <seanb> Guus: Discussion in Amsterdam are that current semantics of isDefinedBY are the same as inScheme
15:38:57 <seanb> Alistair: What do we mean by Ralph's interpretation?
15:39:06 <seanb> ...do we simply mean functional?
15:39:37 <seanb> Guus: Rationale in going from inScheme to isDefinedBy was that semantics of
15:39:54 <seanb> ...inScheme seemed to be the same as isDefinedBy. So go for a general non-SKOS solution
15:40:26 <seanb> Ralph: circular argument. isDefinedBy has such loose semantics, so such a claim seems unsatisfying
15:41:12 <seanb> Quote was: sDefinedBy may be used to indicate an rdf vocab in which a resource is described
15:41:28 <seanb> Jon: Is a concept secheme the same as an rdf vocabulary? 
15:41:57 <seanb> Guus: If we have evidence from use cases, we simply reopen the issue.
15:42:17 <seanb> Jon: It's not whether or not it works, it's about concept scheme == rdf vocabulary
15:42:38 <seanb> Alistair: Made a statement about SKOS concept schemes and OWL ontologies, but no
15:42:49 <seanb> ...statement about "RDF Vocabularies".
15:43:20 <seanb> Guus: Is this different because it would allow linking to an OWL vocabluary rather than a concept scheme
15:43:41 <seanb> Jon: WOrding of isDefinedBy talks about rdf vocabularies.
15:44:03 <seanb> Antoine: Can see a problem. Original guide says that inscheme is a link bwteeen concept and concept
15:44:21 <aliman> From http://www.w3.org/2006/07/SWD/wiki/SKOS/Reference/ConceptSchemes ... 
15:44:22 <aliman> "The choice to leave the formal semantics of skos:ConceptScheme undefined has been made to allow different design patterns to be explored for using SKOS in combination with more formal languages such as OWL, and for using SKOS with query languages such as SPARQL.
15:44:24 <aliman> For example, interpreting skos:ConceptScheme as a sub-class of owl:Ontology would be consistent with the SKOS semantics. This would also be consistent with using owl:imports to make logical import statements between SKOS Concept Schemes.
15:44:26 <aliman> Interpreting skos:ConceptScheme as a sub-class of the class of named RDF graphs would also be consistent with the SKOS semantics. This would also be consistent with using the name (URI) of a SKOS Concept Scheme in SPARQL queries as the name of an RDF graph, to establish, for example, the provenance of a semantic relationship between two SKOS Conceptual Resources."
15:44:27 <seanb> ...scheme it's part of. No requirement that it has to give a meaning. isDefinedBy we'd expect
15:44:31 <seanb> some *definition*
15:45:14 <aliman> Except for the semantic condition stated above, the formal semantics of skos:ConceptScheme are undefined.
15:45:22 <Zakim> +??P24
15:46:13 <guus> guus has joined #swd
15:46:26 <seanb> Alistair: talks through definition
15:46:47 <seanb> ...this allows use of owl:imports rather than defining a new import mechanism
15:47:47 <seanb> ...wanted to find solutions to problems without trying to redefine or invent our own solutions
15:48:15 <Zakim> -??P24
15:48:16 <seanb> Guus: We should reopen the issue regarding inScheme, but not w.r.t. containment,
15:48:30 <seanb> ...rather the choice of skos:inScheme and rdfs:isDefinedBy
15:48:58 <seanb> Alistair: Several different flavours of inScheme. 
15:49:32 <seanb> Guus: Solution might be that someone proposes that we leave inScheme as a subproperty of isDefinedBy
15:49:47 <seanb> Ralph: Don't see how that helps. What's the range?
15:50:13 <seanb> ...understand the range of isDefinedBy to be RDF vocabulary (whatever that is)
15:50:22 <seanb> Guus: And range of inScheme is conceptSCheme?
15:51:08 <seanb> Ralph: Concept scheme doesn't necessarily describe concets. It;s a grouping of con cepts.
15:51:35 <seanb> Alistair: We never really got into this much detail. 
15:52:01 <seanb> ...didn't get into the whether things were defined. Used language like concepts "participate" ina scheme
15:52:02 <Zakim> -Clay
15:52:13 <seanb> Ralph: Where., as a user, should I find a definition for a concept?
15:52:37 <seanb> Alistair: derefence the URI
15:53:42 <seanb> Sean: confused now about derefencing URI and isDefinedBy
15:54:18 <Elisa> If it's at all helpful, the "formal" definition of a "concept system" from ISO 1087 is "a set of concepts structured according to the relations among them".  This doesn't necessarily say that a concept system is an ontology, but is somewhat stronger than a simple collection of concepts.
15:54:36 <seanb> Alistair: If you're using slash namespace, get lots and lots of redirects. 
15:54:51 <Zakim> +[LC]
15:54:52 <Clay> zakim, LC is Clay
15:54:52 <Zakim> +Clay; got it
15:54:56 <seanb> ...if you have an isDefinedBy then you don't need to get it every time.
15:55:02 <guus> [welcome back, Clay]
15:55:20 <seanb> Ralph: That's an operational argument. Given a property URI, how do you find the namespace within which that
15:55:27 <seanb> ...property is defined.
15:55:53 <seanb> Alistair: Why can't you dereference a property URI?
15:56:13 <seanb> Ralph: YOu can. Not clear where in a chain of redirects you encounter the namespace
15:56:31 <seanb> ...can make some guesses.
15:57:40 <seanb> Jon: Can somebody explain why we're not defining a concept scheme as a collection?
15:57:53 <seanb> ...then use isMember
15:58:03 <seanb> Ralph: Does that satisfy the use cases?
15:58:08 <seanb> Jon: Not certain.
15:58:27 <seanb> Alistair: Reason why we might not go there is that some people think of statements to be part of a concept scheme.
15:58:39 <seanb> ...included that in original wording.
15:58:56 <Ralph> s/isMember/rdfs:member/
15:58:58 <seanb> Guus: We have to round up this discussion. 
15:59:22 <seanb> ...For OWL ontologies, we never explicitly defined containment. 
15:59:49 <seanb> ...Reluctant to open a can of worms. However, we do need tio 
16:00:06 <seanb> ...continue this discussion. Will someone reopen the issue? Initially
16:00:16 <seanb> ...on inScheme vs isDefinedBy.
16:00:52 <aliman> It would be great Jon could point to some use cases re. potential issues with inScheme
16:01:35 <seanb> ACTION: Antoine to summarise inScheme vs isDefinedBy and decide whether or not to reopen the issue.
16:02:09 <seanb> Guus: For next week would like to discuss Concept Schemes vs OWL Ontologies.
