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

Wed Oct 28 03:43:36 EDT 2009

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/
<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

<http://www.example.com/resources/links/link1> ">
<rdf:subject rdf:resource="
