January 2008 - ogsa-dmi-wg

Updated draft and Telecon notes
by Steven Newhouse 31 Jan '08

31 Jan '08

All, Michel and I went through the current draft of the document on the call today. We accepted all of the editorial changes in the document and worked our way through the comments. Change tracked text in response to the comments is in the latest draft: https://forge.gridforum.org/sf/docman/do/downloadDocument/projects.ogsa-dmi… Could Mario and Allen please review these changes to see if they satisfy the points they have raised? A quick response would be appreciated so we can meet our target of a final WG call this week. Michel now has the pen to add in a schema reference in a few places and to include the XML representation of the common data elements. Steven

Re: [ogsa-dmi-wg] OGSA-DMI: WSDL and XML Schema
by Michel Drescher 30 Jan '08

30 Jan '08

Folks, here's an iteration of the WSDLs and XML Schemata I sent this Monday. It now includes the WSRF rendering which, by inclusion is interoperable with the WS-I SP rendering. Formally the WSDLs won't validate as I intentionally left out the bindings.

DMI Telcon
by Mario Antonioletti 30 Jan '08

30 Jan '08

Hi, A short reminder that we should be having a DMI telcon today. Note that I will not be able to make it, my apologies as this seems to be quite an important call, and I think Ravi too may not be available. Details: Date: 30th January 2008 When: 9am (Pacific) 10am (Central) 5pm (UK) PIN: 2719140 USA: +1 866 500 6738 (Toll: +1-203-480-8000) UK: +44 118 909 2000 a plausible agenda for this meeting will be: Agenda: 1. IPR Notice 2. Previous Minutes and Action Review 3. Agenda Bashing 4. Spec Review - Comments by Allen and Mario - Require some statement as to what is going to happen with the Schema and WSDL in the spec, i.e. renderings in other documents (?). 5. XML Schema/WSDL generation progress 6. Planning 7. AOB Outstanding actions: [Michel] Refactor XML Schema and WSDL to have a common core and then use these to come up wih WS-I and WSRF renderings. This was posted out. Can change the above agenda on the call as required.

Uploaded new draft
by Steven Newhouse 24 Jan '08

24 Jan '08

https://forge.gridforum.org/sf/docman/do/downloadDocument/projects.ogsa-dmi… I've cleaned up the text in the version Ravi sent to me following on from the call. I see the following outstanding issues: * References * Should an Enumeration element be used for the DMI State in 5.1.2.1 instead of a string? * Removal of XML and updating it to a different document I think it is nearly there and we should think about what else (if anything) needs to be done before making a final group call. Talk to you all next week on the telecom. Steven

Telcon Minutes from 23 January
by Mario Antonioletti 24 Jan '08

24 Jan '08

OGSA-DMI Telcon - 23 January 2008 ================================= Attendees: Steven Newhouse, Microsoft Mario Antonioletti, EPCC Ravi Madduri, ANL Allen Luniewski, IBM Apologies: Michel Drescher, Fujitsu Agenda: 1. IPR Notice 2. Previous Minutes and Action Review 3. Agenda Bashing 4. OGSA F2F DMI Feedback 5. Ravi's changes to the spec - data aggregation - retries 6. Other spec changes 7. XML Schema/WSDL generation progress 8. OGF Planning 9. AOB +--- Actions: [Steven] Add a rationale in the spec for the current position on the interpretation of [data EPRs] as an option and migration strategy. [Michel] Refactor XML Schema and WSDL to have a common core and then use these to come up with WS-I and WSRF renderings. Ongoing. [Ravi] Add the retries content to the spec. Done. [Ravi] Concretise and add the aggregation content to the spec. Done. 2. Previous Minutes and Action Review Done. 3. Agenda Bashing People happy with the agenda. 4. OGSA F2F DMI Feedback Steven sent a link to the group with the outcome of the OGSA f2f discussion: http://tinyurl.com/36ryex The only thing that has an immediate impact is the way we inspect and use the data EPRs to go and look up for things in services. This may lead to public comments. Need to make sure that the spec documents that the rationale for the choices that we have made is clear - e.g. this is seen as an optional and migration strategy and eventually the sources and sinks will mint the data EPRs. Steven took an action to put some clear text in the spec about this. Security also came up but that is a general problem for everyone. 5. Ravi's changes to the spec - data aggregation - retries >From Michel: Fine with the content. However: - The schema for the instance attributes, and the Attempts element, is in the wrong place and should go to the Data Transfer Instance section. - The Data Transfer Instance abstract interface definition lacks a "[attempts]" information model element. - The section explaining the instance attributes should get the explanation of the "[attempts]" information element. and the concrete schema ten should move to the appendix. - The status diagram needs updating reflecting that a service may move from a failed state to the scheduled state, allowing the retries feature. Ravi will do the changes that Michel suggested and pass on the spec to Steven. Allen will try to have a look at the text and will comment if required. 6. Other spec changes Figure 1 has got screwed up. Ravi will fix before he passes the document on to Steven. 7. XML Schema/WSDL generation progress >From Michel: No progress so far - have to fire fight a crisis towards the end of this week. 8. OGF Planning Ravi, Mario and Steven will be attending OGF. One 90 minute session has been booked which will be taking place on the Monday, 13:45-15:15. Plan to give an overview of the spec and then walk through it. Michel wants to dial in, Allen may be able to dial in. Mario can take notes, Steven can present and Ravi can chair - folks seemed happy with this arrangement. Consensus was reached to do a last call before OGF. May have to do this afore the WSDL/XML Schema is ready. In points where there are differences in the spec text and the XML Schema/WSDL then the spec text is normative. Try to reach last call by the end of next week (or did we really say this week - which is what I wrote?). Update and submit for initial GFSG review. Everyone should go through the document to make sure that there are no silly typos. 9. AOB Nope +-----------------------------------------------------------------------+ |Mario Antonioletti:EPCC,JCMB,The King's Buildings,Edinburgh EH9 3JZ. | |Tel:0131 650 5141|mario@epcc.ed.ac.uk|http://www.epcc.ed.ac.uk/~mario/ | +-----------------------------------------------------------------------+

All: I am having a terrible luck trying to download the latest version of dmi spec from the gforge. The connection to forge.ogf.org times out on me and I cannot figure out why it is happening. I would appreciate it if one of you could send me the draft. I will meanwhile raise an issue with ogf folks.
