* Naregi updatges
Brief explanation of NAREGI PSE architecture from Yamada-san.

Q: Is the archive created manually or automatically.
A: It is created automatically by the registration service.

Q: Are there any use cases where output data are put back to ACS after 
   execution?
A: Not in the current architecture.
   But we may try to store output data in the future.
   However, even in that case, it's not sure to store the data in the ACS
   repository. Because we are now redesigning NAREGI PSE. We may adopt 
   the pure ACS repository or simultaneous use of the ACS and the Application
   Pool that we already have in the NAREGI PSE.  

Q: How about the relationship with CDDLM?
A: They focus on Grid/Web services while we focus on legacy applications and 
   source code compilation. This point is a large difference.
   
Q: Do you have multiple binaries for each of the target platform in a
   single archive?.
A: No. They are registered as seperate archives and the Information Service 
   manages the relationship between the binaries and the source code.

Keisuke's comment:
 ACS will provide sort of key attributes so that users can identify each files.
 So it is possible to contain muitiple binaries in a single archive.
 The granularity of archives depends on users.


* Date for F2F
Date:  May 23 and 24
Place: Washington D.C.
 - detailed information about location and lodging will be posted later.


* Research updates on CDDLM, security, etc.
+ CDDLM
 Sachiko sent a summary of CDDLM specs and some questions to the CDDLM ml and 
 have not received any response yet.
 
 More questions on CDDLM specs were raised:
 - How to deploy legacy application. Is a web services wrapper always required?
 - Can we deploy an application server using CDDLM services? 
 - What is the relationship with WSDM and CDDLM? 
  => CDDLM seems to use WSDM.

+ Security
 Mike looked into WS-I security profile and WS-Security.

 Agreed that we don't need to cover all of the security aspects in our spec
 since there already exist standards such as WS-I and WS-Security.
 The least things we should define are: 
  - mechanism to sign the archives to detect modification
  - mechanism for authorization (e.g. how to define roles)


* Issues list

To avoid duplication of tracker items, collect items first, then select
