I agree with the principles in Jim's suggestions, but have a couple of observations / clarifications.
a. You sensibly suggest that we provide information on the most recent modifier of the resource, and you propose doing this via a dc:contributor element. Using this element bends its definition a bit (Dublin Core defines dc:contributor as 'an entity responsible for making contributions to the resource' as opposed to 'the most recent entity that made contributions to the resource'). This is the closest that Dublin Core comes to defining the last modifier, so the question is one of general principle - are we happy to infer meaning to DC metadata elements in the OSLC-RM context which isn't present in their DC definition? b. Have I understood your proposals about creator/modifier elements correctly? I think you are suggesting that the resource creator and modifier can be described as (i) free form text, (ii) an rdf:resource URI to a person resource, or (iii) an inline FOAF definition of the person. Is this right?

I have some minor changes I'd like to propose. First, is to make a distinction between the original creator of a resource, and the most recent modifier of it. The Jazz storage services currently make this information available, and use these DC terms for them. Also instead of allowing free form creators and dates, we say that a creator or contributor can be referenced with a URI, <rdf:RDF xmlns:oslc="http://open-services.net/xmlns/common/1.0/ <http://open-services.net/xmlns/common/1.0/> " xmlns:dc="http://purl.org/dc/terms/ <http://purl.org/dc/terms/> " xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns# <http://www.w3.org/1999/02/22-rdf-syntax-ns> " <oslc:Link rdf:about="http://www.example.com/resources/links/link1 <http://www.example.com/resources/links/link1> "> <rdf:subject rdf:resource=" http://www.example.com/resources/requirement55 <http://www.example.com/resources/requirement55> " /> <rdf:object rdf:resource="http://www.example.com/resources/workitem24 <http://www.example.com/resources/workitem24> " /> <rdf:predicate rdf:resource="http://www.example.com/types/implementedBy <http://www.example.com/types/implementedBy> " /> <dc:creator rdf:resource="http://example.com/users/developer1 <http://example.com/users/developer1> " /> <dc:created rdf:datatype="http://www.w3.org/2001/XMLSchema#dateTime <http://www.w3.org/2001/XMLSchema#dateTime> "> 2009-10-20T19:49:47-04:00 </dc:created> <dc:contributor rdf:resource="http://example.com/users/admin1 <http://example.com/users/admin1> " /> <dc:modified rdf:datatype="http://www.w3.org/2001/XMLSchema#dateTime <http://www.w3.org/2001/XMLSchema#dateTime> "> 2009-10-20T19:49:47-04:00 </dc:modified> </oslc:Link> </rdf:RDF> or allow the use of FOAF vocabulary (second example) <rdf:RDF xmlns:oslc="http://open-services.net/xmlns/common/1.0/ <http://open-services.net/xmlns/common/1.0/> " xmlns:dc="http://purl.org/dc/terms/ <http://purl.org/dc/terms/> " xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns# <http://www.w3.org/1999/02/22-rdf-syntax-ns> " <oslc:Link rdf:about="http://www.example.com/resources/links/link1 <http://www.example.com/resources/links/link1> "> <rdf:subject rdf:resource=" http://www.example.com/resources/requirement55 <http://www.example.com/resources/requirement55> " /> <rdf:object rdf:resource="http://www.example.com/resources/workitem24 <http://www.example.com/resources/workitem24> " /> <rdf:predicate rdf:resource="http://www.example.com/types/implementedBy <http://www.example.com/types/implementedBy> " /> <dc:creator rdf:resource="http://example.com/users/developer1 <http://example.com/users/developer1> "> <foaf:name>Dan Developer</foaf:name> <foaf:mbox rdf:resource="mailto:[email protected] <mailto:[email protected]> " /> <foaf:img rdf:resource="http://example.com/users/developer1/photo <http://example.com/users/developer1/photo> "/> </dc:creator> <dc:created rdf:datatype="http://www.w3.org/2001/XMLSchema#dateTime <http://www.w3.org/2001/XMLSchema#dateTime> "> 2009-10-20T19:49:47-04:00 </dc:created> <dc:contributor rdf:resource="http://example.com/users/admin1 <http://example.com/users/admin1> "> <foaf:name>Adam Administrator</foaf:name> <foaf:mbox rdf:resource="mailto:[email protected] <mailto:[email protected]> " /> <foaf:img rdf:resource="https://example.com/users/admin1/photo <https://example.com/users/admin1/photo> "/> </dc:contributor> <dc:modified rdf:datatype="http://www.w3.org/2001/XMLSchema#dateTime <http://www.w3.org/2001/XMLSchema#dateTime> "> 2009-10-20T19:49:47-04:00 </dc:modified> </oslc:Link> </rdf:RDF> <jim/> jim conallen [email protected] Rational Software, IBM Software Group _______________________________________________ OSLC-AM mailing list [email protected] http://open-services.net/mailman/listinfo/oslc-am_open-services.net
