Interim draft of deploy API
by Steve Loughran 14 Jan '05

14 Jan '05

I said I'd have something out this week, this is as far as I got. Attached as PDF and the raw openoffice doc, a doc that is in CVS in our deployment project on sourceforge. This is for comment; there a lots of unfinished stuff, not least the detail on every property/operation, detail which can come as I code the WSDL. Note the big section on faults; I've bounced a query over to the ogsa architects on what constitutes appropriate use of WS-BF, how to wrap SOAPFaults and the like. So that may change. I may get told off for my very relaxed "everything is a DeploymentFault" design, but it gives the most forward flexibility, in my opinion. -steve

reviewed copy of the XML-CDL spec; <import>
by Steve Loughran 13 Jan '05

13 Jan '05

Here is an updated copy. It extends the "formatting only changes" version of the doc I sent out last week 1. explicit mention of failure conditions on resolution and stuff 2. detail on how we expect import to work. Query on what the meaning of /.. is? that is, what happens when you try and go up from root. Unix says 'stop at /', windows says 'stop at the base dir of that system', Ant says 'break in unusual ways', but that may be fixed. I worry about relative references in import. 1. Should someone be able to supply a set of docs to resolve in a single deployment? 2. what schemas are to be mandated. For reference, smartfrog lets you only deploy one doc, but since all import paths #import "/absolute/paths/only/something.sf" are resolved in the classloader, you can add other .sf files to the classpath to deploy. Which works when you are deploying over RMI (as the client effectively expands the stuff inline), but not via SOAP or the like. -Steve

Syncing XML schema
by Stuart Schaefer 12 Jan '05

12 Jan '05

As discussed in today's conference, we must synchronize our use of XML schema and common types. I would propose that we come up with some simple names for the schemas and standardize the namespaces. Here is a list of namespaces and schema that are currently used in our documents. xsd http://www.w3.org/2000/10/XMLSchema wsp http://schemas.xmlsoap.org/ws/2002/12/policy wsa http://schemas.xmlsoap.org/ws/2003/02/addressing wsrp http://www.ibm.com/xmlns/stdwip/web-services/WSResourceProperties wsrl http://www.ibm.com/xmlns/stdwip/web-services/WSResourceLifetime wsnt http://www.ibm.com/xmlns/stdwip/web-services/WSBaseNotification wstop http://www.ibm.com/xmlns/stdwip/web-services/WSTopics cdl http://www.gridforum.org/2004/12/CDDLM/XML-CDL/1.0 cddlm-components http://www.gridforum.org/cddlm/components/2004/11/06 cddlm-types http://www.gridforum.org/cddlm/serviceAPI/types/2004/10/11 cddlm-api http://www.gridforum.org/cddlm/serviceAPI/2004/10/11 As Steve mentioned, we also need to add a document that lists our common faults.

Notes from the meeting on 1/12/2005
by Milojicic, Dejan S 12 Jan '05

12 Jan '05

Attending: Jun, Stuart, Steve, and Dejan. Agenda: - Update on the existing specs that underwent public review - Update on the CDL spec and the two forthcoming specs - Planning this Year - Attendance at GGF13 - Various Stuart: Has the Component model document almost complete, but waits for Steve to agree upon some of the issues. If he does not complete it within a week, he will provide the document with the disclaimer on unresolved issues. Steve: Deployment API: Steve is working on the document, within a couple of weeks, he will start working on the WSDL. He still has some open issues with the availability support from WSRF, with endpoints being completely specified. Stuart has issue with the different name spaces; need to agree on the structure of the name spaces and then submit the documents independently. Stuart is concerned with CDL name spaces using www.gridforum/2004/etc. different root name spaces. The best practices need to be consolidated. Some of the component model is a subset of the CDL, so Stuart needs either to be part of the CDL or get included. For Jun's document to be valid we need an appendix that has a reasonable way to add the component model and that all other specs live side by side. Stuart will send the latest revision of the document by the end of the week. The WSDL is absolutely necessary, but it is questionable how to test it. Jun will follow-up on all comments that were provided so far (Keisuke, Steve, Bryan, etc.) before we declare that document is ready for the submission and we make the last call on the CDDLM-WG. This should hopefully happen within a week or so (before the next meeting). Dejan provided update on the SF-based language spec. Wrt GGF13 attendance, we have everyone on the team (Kojo, Jun, Stuart, and Dejan) planning to attend, except for Steve who has a conflict on that date. Next meeting will take place in two weeks. Thanks, Dejan.

Re: [cddlm] XML-CDL ver 1.0 final(?) draft
by Steve Loughran 10 Jan '05

10 Jan '05

Jun, This looks like some aspect of XSD that I don't understand yet (XML Schema is like Perl -its too complex to understand more than the subset you work with) variableType and the element ref declare that they have the attribute lazy: <complexType name="variableType"> <attribute name="name" type="NCName" use="required"/> <attribute name="refroot" type="QName" use="optional"/> <attribute name="ref" type="cdl:pathType" use="required"/> <attribute name="lazy" use="optional"/> </complexType> But it is untyped. Does the attribute defined in the base of the schema get picked up (yes, I guess it would), so there is no need to restate type information? If this is so, what is the purpose in declaring the attribute at all? Just as an aide-memoire to users and XML IDEs? -steve
