6. Primer status
-----------------
   Updated: http://lists.w3.org/Archives/Public/public-ws-chor/2006Jan/att-0019/primer.html

SRT: Updates made are in line with F2F requests. Section 3.2 varies in the example in what we discussed.
Provided a degenerate example, other than it helps us explain choreography. SRT described the simple diagram
that will be included.
Brown: First interaction should be a simple MEP rather than an exception.

NEW ACTION: SRT/Remove causeException in this interaction.

SRT: Describe subsequent sections briefly. Complete example is in Section 3.3.10.


7. Formal semantics status
--------------------------
SRT: Kohei Honda says that we plan to submit the drafts at the beginning of next week. This may be delayed.

8. Implementations status
--------------------------
	1. Pi4 Tech
	2. Imperial College
	3. TrustCom

SRT: Awaiting TrustCom. Imperial College is looking interesting (Howard Foster).

Action: SRT/Check with Foster on implementation and progressing to CR.

Brown: Revisit the reasons for restricting recursion on the perform activity, as I think this makes certain use cases complicated to specify in WS-CDL.
What happens if activities occur outside of the recursion.
Chapman: Will summarize in an email and put in Bugzilla.

NEW ACTIONS Brown: Send summary email.
NEW ACTION: Chapman: Enter into Bugzilla.

9. Talks and papers
-------------------
Barreto: Could present at technical plenary (15 minutes).
Will there be a F2F prior to plenary?
Chapman: It is good idea to spend time on examples and exit criteria. Secondly, is end of Feb appropriate?
This meeting could be informal. We could delay to March 2006.
Barreto: An informal meeting would be fine.
Chapman: Dates will be 23-24 February 2006 in Dublin in informal meeting.
SRT: Can't attend then.
Chapman: The alternative is after the plenary.
Look at future dates and advise.

NEW ACTION: SRT and Chapman/Establish F2F date for spring 2006.
