We had a good meeting today with the CDDLM team during the OGSA F2F. The minutes from today will contain details, however I wanted to capture some additional points specific to ACS: 1. A need for an integration point between ACS and CSG (Candidate Set Generator) was raised today, by Andrew I believe. This means that the CSG would need to be able to get the application metadata in order to make an appropriate decision on where a particular job can execute. I propose therefore that this be considered to ensure that either the entire property set be defined in our spec or that the spec allow for dynamic properties which could be provided by the client when constructing the archive (admin data?). These would be accessible by the CSG via WS-ResourceProperties, as stated in the strawman. Is there a standardized namespace to cover such things that would be required (memory utilization, disk space, time, speed, bandwidth, OS, containers, etc)? 2. Andrew also raised a use-case which involves making a copy of an AA and creating a new AA from it by extending it and overwriting some of the contents with perhaps different DD information which might have some particulars for a different organization. This would mean that the new AA would have a new EPR. We may want to consider this and whether or not our current set of portypes is sufficient. 3. Work shall proceed to design a more complete abstract interaction diagram which captures all the moving parts: EMS: BES, EPS, CSG, JSDL, CDDLM, WS-Agreement, WS-Naming, etc. This would build on the EMS box slide and would contain boxes representing all the parts to represent more of the ideal goal. It will most likely be presented at the next GGF. 4. We should also probably use WS-Names instead of EPRs. WS-Naming will be discussed tomorrow. 5. Idea of using NFS or CIFS as a protocol/means to read/write was mentioned. -- -- Michael Behrens R2AD, LLC Cell: 571-594-3008 ___________________________________________________________ $0 Web Hosting with up to 200MB web space, 1000 MB Transfer 10 Personalized POP and Web E-mail Accounts, and much more.
