Mike, thanks for taking the initiative to get things started. Looks good, but I am unfamiliar with the dates and status of WS-Naming and Solution Installation. I presume you have referenced those dates to check schedule fit, or is this the purpose of the roadmap folks to help sort out? What about specifications that any grid service need to implement? Do we mention these in the "referenced specifications"? Is ACS considered a grid managed service? There are many potential circular dependency issues to work out if so; i.e., if I am a service within the grid container, then I must reference and utilize certain base specification implementations that all grid managed services must so that I can be started, stopped, restarted, installed, removed, scaled and de-scaled. If ACS is a service dependency to any of the just mentioned functions then we are awash in chicken/egg issues (what comes first, the chicken or the egg), and will we need to sort these out in order to produce the "referenced specifications" table.

The list of specifications needs to be expanded perhaps. I am a little confused too on what kind of standards need to be listed. I presume it should be those which the specification depends, not the implementation. Suggestions? I changed the "Excepted Users" section to say: The ACS specification, to be developed by the ACS-WG, is expected to be use initially by the NAREGI project in Japan.

Hi Mike, Thank you for writing the document. I think the WS-RF/WS-N (or OGSA Basic Profile?) should be added to the list. I assume that ACS (ARI) uses WS-ResourceProperty to describe an archive as a resource, WS-Naming to represent a reference to an archive, and WS-BaseFault to define fault messages. I mean, these specs are used in the service definition (wsdl); i.e. the ACS spec depends on these specs. I am not sure whether WS-ResourceLifetime and WS-Notification are mandatory or not. Perhaps WS-Notification is not mandatory. But these kinds of detailed discussion may not be required in the roadmap document. I have no idea about any other standards at this moment. Will we refer to the CDDLM in our spec? How about security issues? In order to deploy or/and manage ACS service, the ACS service may implement the CDDLM or/and WSDM interface, but I believe this is an implementation matter and out of the ACS spec's scope. Other comments: - The title of the chapter is "OGSA normative interface schedule" and the word "interface" reminds me of Web Service portType. But It seems that the word interface is used in the broader sense because JSDL is also included in this chapter. If so, I think it should better be described explicitly that we are going to discuss about the archive format for the grid application as well. - I assume that the Business Grid is also a expected user. (It needs Keisuke's confirmation, though.) Sachiko At Sat, 14 May 2005 12:18:37 -0400, Michael Behrens wrote:

Thanks! - I'll add the input your provided and we can discuss it in detail perhaps during the next telecon. I'll have a copy ready to send out. This is all draft, so we'll be able to make changes later in the month before GGF14. Sachiko Wada wrote:

Hi Keisuke and Sachiko, This subsection "expected user" is intended to describe dependencies among specifications. Which specification depends on ACS spec? Please do not list up Grid projects or products. I think possible users of ACS specification is (next version of) CDDLM specs, sophisticated EMS related specifications, or SDD specs. If you don't have such spec at this moment, leave it blank. Thanks, ---- Hiro Kishimoto
