RE: Profiles Ontology

Hi Antoine,
don't hurry, I'm watching this email list and Issue 7 [1] :-)

Hi all,
today I had a deeper look into the Profiles Ontology [2] and matched its features against the profile as defined by ODRL [3].

The Profile Ontology describes a profile as "A named set of constraints on one or more identified base specifications or other profiles, including the identification of any implementing subclasses of datatypes, semantic interpretations, vocabularies, options and parameters of those base specifications necessary to accomplish a particular function."
By my understanding the key feature of such a profile is to apply constraints on the wider specifications of an information exchange standard. ODRL-related example: ODRL defines multiple sub-classes of the Rule Class (Permission, Prohibition, Duty, Obligation) and such a profile may define that only the Permission sub-class may be used.

The ODRL Information Model describes a profile as "An ODRL Profile MUST be defined to provide vocabulary terms (....) that can be used in ODRL policies requiring additional semantics." Details regarding how to define a profile are defined in the ODRL Profile Mechanism. 
My conclusion: reading the description and having a look at the items of the Profile Mechanism I see "additional" as the key term used there. And the ODRL profile specification does not even allow to apply constraints on what is defined as the ODRL Core Vocabulary/Profile.

By my view these two profiles act quite differently: the Profiles Ontology narrows down, a ODRL Profiles defines additional terms, beyond the specification.
I'm interested to read if my conclusions are wrong - also as I have taken the role to be behind the use of ODRL profiles.

Btw: unfortunately I will not be able to join the call on 4 February (I'll be skiing and throwing a snowball to Australia :-) )

Best,
Michael

Hi everyone,

I have probably raised the profile work of DXWG in some discussions, especially with Michael. But not in the recent week. Btw I'm not forgetting I need to come back and read what Michael has written on ODRL profile recently!

Cheers,

Antoine

That bit’s not in the FPWD but will be in the 2nd PWD. When we have it written in to the space doc, I’ll make sure to let you know.

It describes the general pattern of narrowing the scope of a specification with additional, but consistent, constraints, and is particularly relevant to data exchange situations where conformance to such profiles is expected and carries additional context. The Profiles Ontology enables profile descriptions to specify the role of resources related to data exchange such as schemas, ontologies, rules about use of controlled vocabularies, validation tools, and guidelines. The ontology may however be used to describe the role of artifacts in any situation where constraints are made on a the usage of more general specifications.”
