   Action: Keisuke, to compile issues raised at GGF15 sessions. (Done Oct 12)

* Review of the proposed draft for the chapter 7 AAF in the draft 0.51.
   - Relationship to SDD. 
     For the version 1.0, we don't have any dependencies to SDD.
     Convergence with SDD will be addressed in the open issues chapter.
   - Version format.
     Mike's question: Why do we use xsd:string type to describe version 
     instead of using separate types such as major, minor, etc.
     Answer: The spec should accept various version numbering semantics enforced
	by any development environment (tools) to be used with ACS.
   - Uniqueness of AAID
     Sachiko's question: If different producers try to create AA instances
     that have same AAID, is it failed?
     Answer: Yes. AAID must be unique in a repository. The combination of the
     name and version element in the AAID should be kept unique in the 
     repository between producers.
   - AccessConstraint.
     This element specifies security policy for information contained in
     Application Archive, thus mainly it should be about access control.
     The generic security policy should be described and kept by system
     implementation rather than by each AA. 
     This element should be optional. 
   - CheckSum for each content.
     The term "digest value" may be more appropriate. We need check other
     standards like XML Signature.
   - Differential AAD.
     Mike's question: Can binary differentials be included in AA?
     Answer: The differential here is in a granularity of Application Content.
     Differential updates finer than it, for example using a binary patch,
     is not specified in ACS, though they can be practiced in a implementation
     specific way with prior agreement between producers and consumers.
   - Version management.
     We currently have only simple attributes that indicate parent and 
     immediate children. For future discussion, Mike suggested adding 
     attributes to describe richer dependency information between AAs. 
   - Physical format.
     Mike suggested having auto installable format in order to help
     automated provisioning. One may execute GetContents automatically 
     to obtain content on which it depends.
     Agreed to discuss about this as an open issues.
   Action: Keisuke, to merge section 1.3 Notational Conventions and 1.4 
     Namespace (posted on Sep 26 by Sachiko) to the draft. (Done Oct 14)
   Action: Sachiko, to add XML schema diagrams.
   Action: Keisuke, to compress and simplify the description, especially 
     the Differential AAD section.
   Action: Mike, to post his proposal for AAD to the ml. (Done Oct 12)

* Updates
   Keisuke attended CDDLM teleconf on Oct 12 and discussed possible
   interaction between ACS and CDDLM. The conclusion is either of three
   sequences Stuart proposed will work and there is no preference from
   ACS view. 

* Next meeting
   Date: Oct 19 Wed 20:00 EDT/Oct 20 Thu 9:00 JST 
   Calling #: will be announced later
