All,
The Roadmap editor would like to get some input for the new OGSA RoadMap document....what is currently in the document is shown below....perhaps we can update the dates with the actual values and propose challenging v2 draft date?  Open for discussion....we'll be able to meet at GGF-18 and discuss, however the mark-ups are needed before the end of this month.

Thanks!

1.1        Application Content Service Specification Version 1.0

The grid community currently manually creates and manages grid application content consisting of executables, scripts, and data.  The Application Content Service (ACS) specification specifies a set of Web services that provide a way to archive components for stable storage and retrieval within a standardized format.  This allows grid applications and their data to be packaged, stored, and then referenced over time as needed across domains.

ACS does not interpret or execute information in the contents; rather it just manages the contents for use by other OGSA services.

1.1.1        Development Schedule

The Application Content Service Working Group (ACS-WG) is now developing this specification. 

Milestones

First draft available, June 2005

Ready for public comment review, October 2005

GFD-R.P publication, December 2005

Table 4‑11 ACS Specification 1.0 document schedule

The final specification is expected to be completed during 2005.  The Business Grid Computing project will provide an open-source reference implementation by early 2006.

1.1.2        Referenced Specifications 

This specification will refer to OGSA WSRF Basic Profile 1.0 and the Installable Unit Deployment Descriptor (IUDD) specification being developed by the OASIS SDD-TC.  Either RNS or WS-Naming is also expected to be referenced, since application archives can be referenced externally.

Table 4‑12 ACS 1.0 referenced specifications

1.1.3        Expected Use

Given that ACS and IUDD are complementary, IUDD will refer to ACS in order to cover grid scenarios. Since ACS provides an API to an archive for applications and data, it is anticipated that job management and advanced execution specifications would use the application archive interface for applications under the control of a business manager. Thus future EMS architecture documents and advanced EM profiles may refer to the ACS specification. Also, since the application archive may include multiple component types, including configuration description and job control flow, future versions of the XML-CDL specification may refer to the ACS specification.
