[OSLC-ArchMgmt] [OSLC-RM] Suggestions for link resource

I think you understand my intent.
When it comes to creator/modifier I think allowing all three options will
be useful, each providing a different level of content that could be
exploited by clients automatically.
Regarding the choice of the dublin core terms, I am not really hung up on
those in particular, but rather I think it useful to have both the creator
and most recent modifier available to clients looking at this resource. I
for one an comfortable with this use of DC, but have no objections if the
workgroup would rather find another public term, or invent an OSLC
(common) one.

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 would agree)

I'd like to amend to this another option for specifying the
creator/modifier of a resource link We can also permit the use of the FOAF
vocabulary:
<dc:creator rdf:resource="https://liz:9443/users/adam">
<foaf:Person:>
<foaf:name>Adam Administrator</foaf:name>
<foaf:mbox rdf:resource="mailto:adam at example.com." />
<foaf:img rdf:resource="https://liz:9443/users/adam/photo" />
</:foaf:Person:>
</:dc:creator>

Looking over the details of the link resource currently proposed for OSLC
RM (and currently suggested for OSLC AM as well). 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/"
xmlns:dc="http://purl.org/dc/terms/"
xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#"
<oslc:Link rdf:about="http://www.example.com/resources/links/link1">
<rdf:subject rdf:resource="http://www.example.com/resources/requirement55"
/>
<:rdf:object. rdf:resource="http://www.example.com/resources/workitem24" />
<:rdf:predicate rdf:resource="http://www.example.com/types/implementedBy"
/>
<dc:creator. rdf:resource="http://example.com/users/developer1" />
<:dc:created rdf:datatype="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" />
<:dc:modified rdf:datatype="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/"
xmlns:dc="http://purl.org/dc/terms/"
xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#"
<oslc:Link rdf:about="http://www.example.com/resources/links/link1">
<rdf:subject rdf:resource="http://www.example.com/resources/requirement55"
/>
<:rdf:object. rdf:resource="http://www.example.com/resources/workitem24" />
<:rdf:predicate rdf:resource="http://www.example.com/types/implementedBy"
/>
<dc:creator. rdf:resource="http://example.com/users/developer1">
<foaf:name>Dan Developer</foaf:name>
<foaf:mbox rdf:resource="mailto:admin1 at example.com." />
<foaf:img rdf:resource="http://example.com/users/developer1/photo"/>

<foaf:img rdf:resource="https://example.com/users/admin1/photo"/>
</:dc:contributor>
<dc:modified rdf:datatype="http://www.w3.org/2001/XMLSchema#dateTime">
