We send the messages but they do not seem to be delivered. In the following some doubts we had. Thanks for your attention. 1. I've seen in the Test Plan of the Deployment API and I had a doubt about Test 13. The Unsubscribe operation mentioned there should be invoked where? It is neither defined in the System nor in the Portal WSDL. 2. Another doubt is about the Events of the System. When a Lifecycle transition happens, should we send both a "LifecycleEvent" (from "SystemNotificationTopics" TopicSpace) and the "Lifecycle Event" from the Component Model? 3. We also want to know why the system and the portal do not implement the Notify operation as they are event consumers. Thanks, Ayla

Doubt about "Resolve" operation on System
by Ayla Debora Dantas de Souza - Projeto Ourgrid 11 Aug '05

11 Aug '05

Hello all, we are implementing the "Resolve" operation from the System and we had the following doubts: 1. What should happen if in the "path" we specify a prefix, but in the CDL being queried that prefix is not defined? As far as we know, XPath does not support queries using namespaces, only prefixes. Considering this, the prefix used must be defined on the XML being queried. Are we right? 2. What must happen when the "path" passed for the "Resolve" does not present a prefix? We think that in this case, a response representing an emply result should be returned to the user. Ok? Thanks, Ourgrid team.

Ayla, This is not correct. If a node is defined by a qname, then specifying the namespace is the only way to get the proper return value. So, if the path contains a prefix, how do you "know" that its prefix corresponds to the namespace of the node you are looking for?

Notes from the CDDLM meeting, 8/10, 2005. Notes taker, Dejan Milojicic. Attendees: Ayla, Jun, Stuart, and Dejan. 1. Update on the progress with reference implementations Ayla: they are doing well, some problems with Tomcat, but decided they will relax the tests (10MB, 30 deployments one after another; found out how they can make deployments smaller through re-use; they implemented more tests, corrected some parser bugs). At the moment they have completed the whole cycle. Still working on the implementation of the system service, some issues with other methods, such as how to change properties. They plan to attend GGF15 and demo, looking forward to hear the feedback from the rest of the team. E.g. Problems with import and other questions. Ayla will summarize all questions they have. Jun: making complete implementation of the parser and now also started implementing component model. This is ongoing. He will be able to demo at the next GGF. Stuart: Has parser complete, hoping for some test cases, will post some questions for Jun, some circular dependencies in how his parser does placement and prototype resolution, some interesting set of dependencies. Parser is complete and works on the core infrastructure of the deployment APIs, needs 3 more weeks until he is done. Then he will work on individual components. 2. Preparation for the meeting with OGSA Dejan will look at the glossary. Others will give a thought how we fit into the picture. Stuart, Jun, and Dejan will attend, and we expect that Steve will dial in. 3. Planning next activities GGF15: Ayla will attend and everyone else (except for Steve who did not attend this meeting) confirmed that they will do the demo at GGF15 (Stuart, Jun, Ayla). Individual demos will be held with the testing completed. Before the GGF15, all individual owners will work on their test cases and we will have other reference implementation owners run these tests before GGF15. Steve already posed tests for the deployment APIs, Stuart will post his tests in the next few days and Jun will post his in next 2 weeks. 4. Update on the documents Jun will apply changes as requested by the technical area directors; we had the foundation document become the formal GGF document. 5. Use cases Jun asked if SDD can peruse our use cases and the answer is yes. Credit needs to be given to GGF, though. Our next meeting is next week. Thanks, Dejan.

Notes of the meeting on 8/3/2005
by Milojicic, Dejan S 04 Aug '05

Attendees: Steve, Ayla, Dejan. 1. Update on the progress with reference implementations Ayla: did a parser and service, but Tomcat dies after sequential deployments. Working in parallel to finish service, have prototype of the portal of the system, but only using the properties of Muse it works. There are some problems with updating properties. They are implementing more tests. Still confident that the first prototype will be done by end off August. Steve suggested using Jetty instead of Tomcat. Steve: Hasn't done much since GGF because of other commitments. Has completed requirements document and put into the CVS. No information from Jun and Stuart. Hopefully they will join in next week. 2. Preparation for the meeting with OGSA Steve will join (potential 3. Defining agenda for the F2F with OGSA (I need to provide it to Hiro shortly) A) Introduction (learn more about EMS broader picture, in the past wee overviewed CDDLM) B) Defining architectural relationship C) Indebt overview of the CDDLM interfaces (if needed) D) Integration roadmap E) Next steps 4. Planning next activities Meeting are back on the weekly basis. Thanks, Dejan.
