    Last week's minutes were approved.

  2. F2F2 and F2F3

    Proposed dates for F2F2 are Jan 23-24 or Feb 2-3, in Amsterdam or Southampton; a poll is going to be set up shortly. Proposed dates for F2F3 are Jun 22-23 (Santa Barbara) or Boston (July 2 to 6). The objectives (and necessary inputs) for F2F2 were discussed and approved by the working group.

  3. PROV-O

    The prov-o document authors have agreed on an approach to model usage/generation time and qualifiers without a class EntityRole that is a subclass of Entity. They are in the process of modifying the ontology, the examples and the document. Final details such as name of properties are going to be discussed by them in a separate call.

  4. PAQ document

    the editors are planning to have a version ready for internal review next week.

  5. PROV-DM

    The WG recorded three proposals that were approved by email vote during the week. A revision of the document incorporating the recent proposals (and further to be voted on) is going to be produced by the editors.

They are in the process of modifying the ontology, the examples and the document. Final details such as name of properties are going to be discussed by them in a separate call.
