Resolutions
  1. PIL is an assertion language, which allows asserters to make assertions about stuffs and activities in the real world (as they view it) and how they influence each other. link
  2. Derivation expresses that some stuff is transformed from, created from, or affected by other stuff. A thing B is derived from a thing A if the values of some invariant properties of B are at least partially determined by the values of some invariant properties of A. link
  3. we use the set of constraints as a starting point for building an understanding of PIL link

    The previous minutes were accepted; actions-12 is now closed.

  2. F2F Plan

    Sessions for the F2F meeting have been identified. Detailed agenda will be posted the day before the meeting.

  3. Connection TF Plan to F2F1

    Eric reviewed progress. A good catalog of connections is being built up. It will be summarized at F2F1, and it is proposed to categorize contributions.

  4. Implementation and Test Cases TF Plan to F2F1

    Helena indicated that over 30 entries had been submitted. A summary will be presented at F2F1.

  5. Access and Query TF Plan to F2F1

    Simon circulated a summary of activities ahead of the meeting. A series of proposals, and comments on them, have been curated, and will be presented at the F2F meeting.

  6. Model TF Plan to F2F1

    Paolo reviewed activities. A consolidated document, containing definitions for core concepts, and topics for discussion, has been produced. When the document is frozen, a notification will be sent to the mailing list. It was agreed that we shouldn't attempt to incorporate in this document definitions for other concepts that have not been discussed yet.

  7. Model Task Force

    In the spirit of building up our understanding of concepts, agreement was reached on a few more properties. PIL is seen as an assertion language; derivation was defined; a set of event ordering constraints was adopted as a starting point to understand PIL. Consensus was not reached on a definition of Agent since the group is still undecided as to whether the concept should be defined independently of process execution or not.

7. Model Task Force

Summary: In the spirit of building up our understanding of concepts, agreement was reached on a few more properties. PIL is seen as an assertion language; derivation was defined; a set of event ordering constraints was adopted as a starting point to understand PIL. Consensus was not reached on a definition of Agent since the group is still undecided as to whether the concept should be defined independently of process execution or not.
