Daniel: Has provided feedback, but this discussion has not continued. Stian: Is it worth pursuing to get new diagrams for release? Daniel: Just some typos, David had also created some new diagrams that we might not all need.


  • http://www.w3.org/2011/prov/track/issues/442 (what prov.owl terms can we omit in prov.html)
    • https://docs.google.com/spreadsheet/ccc?key=0Ahxrga9AQHb_dDBQV3ZyWEN6S2RXcWVZMzI0S0xKeEE
    • TODO mentionOf in narrative is not clear - use the one from the ontology "The mention of an Entity in a Bundle (containing a description of this Entity) is another Entity that is a specialization of the former and that presents the Bundle as a further additional aspect."
    • Jun's stab: "prov:mentionOf is a special type of prov:specializationOf, which links a more specific Entity to a more general one that is described in a prov:Bundle. prov:asInBundle is used to cite the Bundle in which the more general Entity was mentioned."
    • TODO: Tim to incorporate feedback.
      • Jun: Still awaiting feedback from Tim


  • Daniel awaiting Tim's feedback on 3.2 --> Stian will review
    • Tim to regenerated document, Stian to continue review.
    • Mainly examples have changed
  • Stephan: no bandwidth
  • Satya: willing to review
  • Tim: willing to review, can't help make it.
  • ... assuming that this will pick up in the next few weeks.
  • Daniel: Paul's validator is on the implementation page http://www.w3.org/2011/prov/wiki/ProvImplementations
  • ... link:




  • Waiting for Tim and Stian to review the updates made after review of prov-o july 3 2012 for last call (33 RAISED feedback points left of 100+).
  • Still have to discuss the figures that go in the final version of the document (David did more than the one that is currently there).
    • Agreed to wait until David is available to discuss.

Finishing examples spreadsheet:

  • will be doing another pass this week.


Someone please take
  • stop using trig in prov-o html [1]

  • Ivan's comments http://www.w3.org/mid/2BB8960E-3025-4116-B43B-4185BB99A68F@w3.org
    • his means that there is an editorial issue in the current Last Call which still refers to the TR space (in the abstract)
  • Update figures to latest draft: Well sppotted, I hadn't realized. I have changed it. They are 2 different activities. (see Daniel)
    • Regarding the image with the bundlePost in the html, I have spotted a typo: There is an edge with prov:hadLocation from the pyublicationActivity to the Location, which is incorrect. This edge should be from :post9821v1 instead (as you have it with :post9821v2). Also, there is a "my" prefix in the edge snapshotContent that should be ":" according to the example. Also, as I suggested before i would remove the boxes with "type" and "date" to simplify the although that's just my opinion.
    • Finally, I had to do some small changes to the example, adding annotations to the bundle. Would you mind adding those, please?. (Daniel)
  • Review Daniel's 3.2
  • Luc's scan
