Keisuke and Mike, Here is my understanding.
What about ACS? o General Data Store -- Good Place to Keep Packaged Apps Ready for Deployment (under CDDLM control)
Yes
-- Not Sure Who Specifies the Format of the App Packages
ACS(AAF) specfies the format. But ACS client (such as CDDLM) gets contents through ARI as byte data (either embedded or attached to SOAP message, or any other protocol like gridFtp may be used) and needs not care about the format.
-- But doesn't matter to us!
Right.
o Supports Complex Querying -- i.e., it is an Info Service!
No. ACS does not specify meta information for application itsself. ACS specifies meta information required for ACS to provide ARI operations, i.e., Create/Update/GetArchive, GetContents. The contents in AA are completely opaque for ACS.
-- No Specification of Data Model
No. - Sachiko
