Minutes of Meeting

1. Approval of agenda

2. Approval of MoM from last meeting

3. Sandbox for IIP template set moved (for humans) (for machines)

4. JORD ID spec examples

See forum for examples for PCA RDL classes.

5. Identification of templates
See forum for classification template example.

IIP will implement the ID spec to their template set. Approach: add predicate defaultRdsId to all templates and roles as in Victor´s example - at the end of the predicate use Rnnnnnn where it already exists, add R-UUID where value is null. This new set can then be uploaded to triple store(s) and made available through an endpoint.

It does not seem to be an issue that roles as in the example, e.g. hasClassified, is given a defaultRdsId, and then used in other templates. These generic object properties are redeclared in the template itself.

6. Updates from forum/preparation for namespace discussion
Namespace for Part 4 - some issues identified:

  • possible to have sameAs relations in RDLs
  • should we issue Part 4 in a new namespace?
  • purl server usable?
  • redirects to some database using sameAs relations?
  • it would be advantageous to be technically independent of ISO
  • would it be possible to have some sort of arrangement between PCA and ISO for management?
  • we do not know of any business using these URIs. It might be best to wait until there is a real business requirement

Lillian will talk to Nils and David Leal to find out more about the possibilities and plans for change.

7. Semantic Days in May - reschedule next meeting
Next meeting rescheduled to May 23.

8. A.O.B
HEED will propose plan for work on change management and make it available for a broader group, including MMT and JORD. There is a need for revision and review. MMT will be kept informed.
