RE: Profile definition

Hi, Rob.

Makx can correct me if I'm wrong, but basically DCAT-AP re-uses the Dublin Core [1] and DCAT [2] definition(s) of application profile.

About what we mean with "application profile" and "negotiation profile" (which may not be necessarily the same thing), I think it would be beneficial for our discussion to know more about the background of the Doblin Core AP document. I wonder whether Karen, who co-authored it, can share some insights. Also, I think it would be good to start collecting reference documentation on this topic – I took the liberty of updating the AP wiki page accordingly [3].

Cheers,

Andrea

Thanks Simon,

I was _aware_ of it - but its not yet clear to me whether the scope of application profiles discussed there fully covers the requirements under discussion here.

It would be great if Andrea or someone could provide a pointer to a formal definition as settled on within this community (so far in discussions this has not been offered as a straw man, and only the question "what is a profile" has been raised.)

which I think is where the whole idea of DCAT profiles was most comprehensively discussed until now.

Subject: Profile definition

Looking for a working definition of a profile - here's a starter from Dublin Core [1]


"A DCAP is a document (or set of documents) that specifies and describes the metadata used in a particular application. To accomplish this, a profile:

  *   describes what a community wants to accomplish with its application (Functional Requirements);
  *   characterizes the types of things described by the metadata and their relationships (Domain Model);
  *   enumerates the metadata terms to be used and the rules for their use (Description Set Profile and Usage Guidelines); and
  *   defines the machine syntax that will be used to encode the data (Syntax Guidelines and Data Formats)."

I think service access is possibly another dimension of profile - and in fact I'd like to model profiles as n-dimensional, with the ability to label (soft-type) each of the dimensions an AP chooses to qualify.

So, even though we are not going to define any specific AP, I think we need to decide if we will define a meta-model for an AP, in terms of attachment points for each of these aspects, as well as self-reporting identification of the set of APs a document conforms to.

Any advances on this definition  before I have a go at defining generic Use Case(s) that covers this scope?
