GRAAP Session #1
--------------------------
[Details see slides on GridForge [1]]

- IPR. Participation list.

- Status Quo
 + Experience document is not yet written.
 + Some progress with the negotiation protocol.
 + In general not much progress.

- Comment from Area Chair (Ramin)
 + GFSG asks whether it is possible to specifiy the common subset for the main WS-Agreement use case: advance reservation. Recommendation would be good for upcoming implementations. - A (Wolfgang): Could be difficult.
 + In addition, the question has been raised whether it is possible to describe in the experience document all WS-Agreement parts which have been used and how.- A (Wolfgang): That is easy. [NOTE: Resulted in a questionnaire [2] sent to WS-Agreement implementers]
 + Nothing like an interop. event is needed to prove interoperability.
 + RŽsumŽ: Two documents are needed:
  (1) Experience document for becoming a recommendation. Questionnaire [2] asking some implementers (around 4) how they use WS-Agreement.
  (2) Making a proposal for using WS-Agreement for Advance Reservation of computational jobs.

Questionnaire [2]:
- Use case description (maybe from the survey paper [3])
- Background information
 + project timeline
 + date of implementation
 + website
- Hosting Environment
- WS-Agreement rendering
 + which parts of the template are used/supported
  * start with Dominic's document template
  * portTypes to be added. Ask for additions to the protocol
  * Ask also for extensions to the template/data structure
 + Template(s), Agreement example
 + send questionnaire to known implementations (deadline two weeks from now)

Session #2
---------------
[Details see slides on GridForge [2]]

- IPR. Participation list.

- Discussion on negotiation.

- Existing agreement is the context of the re-negotiation.

- Wolfgang takes notes directly within the slides. Please refer to [4] for discussion results.

- Proposal (Oliver): Client & provider have to share template type system

- [Action]: Ask BREIN guys whether they are ok with this changes

- Next steps:
 + Create new Agreement factory interface inheriting from the old one + getQuote
 + New Agreement state: superceded (adding superceded will result in a loss of backward compatibility) [NOTE (Email from Oliver to GRAAP list "Extension of agreement states for WS-Agreement-Negotiation"): It turned out that this is NOT the case.]
