CDL: on use of cdl:refroot
by Jun Tatemura 31 Jan '06

31 Jan '06

Hi, A notable misunderstanding in the test case is on a use of cdl:refroot in cdl:system. (or on semantics of cdl:system). I would like to note that cdl:system is a toplevel property list (just like a child element of cdl:configuration). Thus, we cannot refer to a child element of cdl:system using cdl:refroot (or cdl:extends either). In cddlm-cdl-2005-02-0005.xml (and similarly, cddlm-cdl-2005-02-0006.xml), <cdl:system> <app> <hostname>localhost</hostname> <database cdl:ref="/hostname"/> <user cdl:ref="." cdl:refroot="toplevel"></user> </app> <toplevel>username</toplevel> </cdl:system> cdl:refroot is trying to find a toplevel property list (defined in cdl:configuration), not a child element of cdl:system. The correct test pattern should be: <cdl:system> <app> <hostname>localhost</hostname> <database cdl:ref="/app/hostname"/> <user cdl:ref="/toplevel"></user> </app> <toplevel>username</toplevel> </cdl:system> I have updated the test case in CVS. Thanks, Jun

On CDL tests
by Guilherme Germoglio 31 Jan '06

31 Jan '06

Hello all, I think I've found a misinterpretation in cddlm-cdl-2005-02-0018 test. The cdl file: <cdl:cdl> <cdl:configuration> <toplevel> <value cdl:lazy="true"/> </toplevel> </cdl:configuration> <cdl:system> <app> <user cdl:ref="value" cdl:refroot="toplevel"/> </app> </cdl:system> </cdl:cdl> The resolution expected: <cdl:system> <app> <user cdl:lazy="true"/> </app> </cdl:system> But the specification states in 7.5.2.2 Example: ... A value reference to this property will not be resolved before the resolution of this @cdl:lazy attribute. So, as the user lazy element in the test was not yet resolved, the reference to it should not be resolved. Is this correct? If so, the resolution expected must be: <cdl:system> <app> <user cdl:ref="value" cdl:refroot="toplevel" /> </app> </cdl:system> The cddlm-cdl-2005-02-invalid-0003.xml test also has a problem. It states that there's an indirect recursive reference. The cdl file follows: <cdl:cdl> <cdl:configuration> </cdl:configuration> <cdl:system> <app> <hostname cdl:ref="database"/> <database cdl:ref="hostname" /> </app> </cdl:system> </cdl:cdl> But the resolution algorithm (p18-19) says the that no cdl:ref/cdl:refroot is copied. So there's no recursive reference and it is a valid cdl. Guilherme

Meeting notes: CDDLM meeting on Wednesday January 4th
by Milojicic, Dejan S (HP Labs) 31 Jan '06

31 Jan '06

Attendees: Ayla, Flavio, Guilherme, Stuart, and Dejan > 1. Update on reference implementations UFCG is on track with their reference implementation. There are questions about some of the problems that Steve has raised with respect to CDL and there are some remaining tests that have not been completed, but the team believes that they will complete their reference implementation before GGF. Softricity will complete Deployment API tests in the forthcoming week and then attack component model. Stuart believes that they will have completed reference implementation before end of January. > 2. Planning GGF16 in Athens Stuart, Steve, and Dejan are confirmed to attend; Ayla and her team will not attend. It is believed that Jun will attend, but this still needs to be confirmed. UFCG team may prepare the demo for someone else to present it at GGF (Steve, Jun?), if they are available given that they will be preparing their own demonstrations. A fallback solution is to do presentation (slides) instead. > 3. Planning OGSA F2F session There is an OGSA F2F next week (1/17) with 2 preparation meetings beforehand. Dejan will attend F2F, Stuart will either attend or dial-in. > 4. Various Regular meeting will take place next week.

CDL q: what does this resolve to (cdl-2005-02-15.xml)
by Steve Loughran 30 Jan '06

30 Jan '06

This is the test #cdl-2005-02-15, and it is failing on my system <cdl:cdl > <cdl:configuration > <node> <value cdl:ref="newvalue" /> </node> <toplevel cdl:extends="node"> <newvalue>newvalue</newvalue> </toplevel> </cdl:configuration> <cdl:system > <app> <user cdl:ref="value" cdl:refroot="toplevel"/> </app> </cdl:system> </cdl:cdl> The reason it is failing is that the reference under <node> only resolves once the thing has been extended; that is, cdl:configuration/node is itself unresolvable. , though cdl:configuration/toplevel is resolveable. My implementation tries to resolve everything under cdl:configuration, and fails because it is not possible here. It would work, if I marked the ref as lazy <node> <value cdl:ref="newvalue" cdl:lazy="true" /> </node> because then the deref would not take place. What do other people's implementations do with this test? -steve

Meeting notes from the CDDLM meeting, January 25th, 6am PST
by Milojicic, Dejan S (HP Labs) 25 Jan '06

25 Jan '06

Attendees: Ayla, Flavio, Guilherme, Stuart, Steve, and Dejan 1. Report from the F2F (Jun and Dejan attended) Dejan went over the slides which constitute the meeting notes from the F2F. Will work with Jun to come up with use cases for the next week's OGSA meeting, 2/1. Stuart will try to attend that meeting as well. 2. Update on the reference implementations Stuart: in the midst of deployment API and then they will be done this week (CDL parser was done earlier and component model mostly complete). Ayla: worked on switch, will finish today, ad some performance and demo scenarios working, using several machines. They will organize it so that someone can use it. So that it is better demo-able. They also work on the tests. Steve: just finished references working, does generation of the SmartFrog. He will be at GGF to demo something. Put up the tests as well. Jun (Dejan speaking for Jun): will attend GGF and do the demo of the NEC implementation. 3. Planning GGF16 in Athens Stuart, Steve, Jun (to be confirmed by Jun), and Dejan will attend. Ayla and her team, and Peter Toft will not attend. 4. Planning OGSA F2F session Will take place on Friday after GGF in Athens. Dejan and Steve will attend, Stuart is trying to reschedule his flight for a later time to enable him to stay longer. Dejan asked that the meeting be held earlier in the morning. 5. Steve's question about reported issues with CDL Steve was filing issues with the tracker, we should do the same for deployment APIs and component model. If everybody does the same, we can make a progress. It need not be bugs, it could also be comprehension problems. Need Jun to discuss this in more detail. Dejan will ping Jun. Stuart: it would be good to file cases and see if it will solve the problem. Resolution extension. Thanks, Dejan.
