[oslc-core] Questions about the creator property

Fri May 7 15:39:25 EDT 2010

Andy,

IMHO, dc:creator should always identify the user who created the resource 
(#2). For applications like CM, there should be another 
application-dependent property that describes the source of the report, 
e.g. "reportedBy", "submitter", etc.

Regards,

I'll repeat a point to consider made much earlier by Samit Mehta:

For many resources, there are two notions of "creator":

1) The person who was first responsible for the content of the resource
2) The tool user (which may not be a real person) whose login id was used
in the OSLC calls when the resource was first created

Many change management tools, for example, will distinguish these:  the
change request may have been taken "over the phone" by a customer service
rep...then the actual customer speaking will be the "creator" in the sense
of (1), and the customer service rep will be the creator in the sense of
(2).

Which one is meant by "creator" in the OSLC core?

Hi Nick,

Thanks for the feedback. I think we may need some tweaks in this area.

I just added some text to the Core spec to clarify how foaf:Person is
supposed to be used:
- dc:creator MUST be either a Resource or Local Inline Resource of
type foaf:Person
- foaf:Person MUST include either a foaf:name or both foaf:givenName
and foaf:familyName

That's is how things stand today. We only allow foaf:Person for
dc:creator and we only support those three foaf:Person properties. In
this area, OSLC Core was trying to approximate what was done in
earlier OSLC specs.

Of course, we still have time to change, and now is the time to get this
right.

Seems like having some form of user ID would be a very good thing and
so I wonder:

1) Have we had user ID in previous OSLC specs and/or have we had some
discussions about the implications of specifying user ID's in
representations?

2) Any opinions about how we use dc:creator in OSLC? Should it be a
simple "full-name" string as the FOAF guidance suggests?

3) Any opinions about if or how we should specify user ID? I think
"foaf:OnlineAccount" would probably be preferable to "oslc:userID" and
preferable to pulling in the SIOC namespace.
