Interop Telcon Notes

DAIS Interop Call - 13 May 2009 =============================== Present ------ Mario Antonioletti, EPCC Steve Lynden, AIST Sunil Ahn, Kisti Agenda ------ - Agenda bashing - Process - Come up with a scenario and database to use - Putting up end points to test - Coming up with a test suite - Roles - Timelines Actions ------- [MAA] To come up with a test plan for WS-DAIR. Started but not complete. --- AIST had issues with the implementation of the OGSA-DAI RDF that required changes to the WSDL in the core spec because of the way that JAXB works. Steven interested if other people run into other issues. Sunil used gSOAP. He had to make a number of changes to the WSDL in order to get it to work but not apparently the same problem that the AIST developer experienced. Mario encouraged folks to use the DAIS mailing list to ensure that the process is open as opposed to using point to point communications. Mike and Sunil have been working on the interop process and it appears that, bar one or two issues, the two implementations seem to inter operate. Really need the test document to give this structure. Mario is going to have another go at progressing this document and pass it on to Steven next week and put up on GridForge. Hope is that something will be ready by the next telcon. Then quickly write the experiences document based on this and complete the process for the WS-DAI and WS-DAIR specs. Sunil asked if there was an OGSA-DAI WS-DAIR client available that he could use to test against his AMGA service. Mario said he would ask Mike.

WS-DAIR inter-op testing
by Mike Jackson 07 May '09

07 May '09

Hi folks, I have deployed OGSA-DAI WS-DAIR 1.0 services onto Tomcat. I checked the consequences of changing our WSDL to use document/literal instead of rpc/literal and our software still built and compiled successfully. And our internal system tests ran happily against this(*) So I've also set up a Tomcat with the document/literal versions also. Both servers have been configured to expose our "littleblackbook" database. The database also has a few stored procedures that can be invoked also (useful for testing SQLResponse resources). Connection info for both servers is at: http://forge.ogf.org/sf/wiki/do/viewPage/projects.dais-wg/wiki/IssuesWithTh… More info, including stored procedures in the database and examples of the difference between doc/literal and rpc/literal on the wire for the services is at: http://forge.gridforum.org/sf/wiki/do/viewPage/projects.dais-wg/wiki/OGSADA… Any problems, let me know... Cheers, mike * Beyond a few failures due to simplistic checking of SOAP fragments, via String matching rather than XML parsing, ahem, but these are not an issue with the specs or with inter-op.

07 May '09

DAIS RDF Call - 7 May 2009 ========================== Present ------- Mario Antonioletti, EPCC Steven Lynden, AIST Miguel Esteban Gutierrez, UPM Agenda ------ - Progress, status of: - DAIS RDF motivational document - query document - ontology documents - Planning Actions ------- [SL] Get a list of the most recent changes that have been made to the RDF query specification by the AIST implementor. Publicise any changes that have been made (tracker/mailing list). [MEG] Get Carlos (ADMIRE developer) to join the DAIS mailing list and encourage him to participate in the spec process. [SL] Create a set of subdirectories in the SVN repository for the RDF ontology and query wsdl/xsd. [MAA] Move the old ontology document into the old documents folder. [MEG] Put the WSDL/XSD for the RDF(S) spec on SVN on Grid Forge. Completed Actions ----------------- [MAA] Read and comment back on the RDF(S) document. Did this but for the document before it was split but the comments are still valid. [MEG] Report back on who from UPM could do an implementation of the query document and on what time lines. Carlos from the ADMIRE project will be doing this. He is currently doing the implementation. It is important that he openly comments on his findings. It would be good if he could join telcons. [MEG] Talk to the ADMIRE developer who is using the WSDL/XSD from the query spec and report back if there are any issues. Done. http://www.ogf.org/pipermail/dais-wg/2009-May/000288.html [MAA] Publicise the availability of WS-DAI/WS-DAIR/WS-DAIX WSDL & XSD on SVN on GridForge. Done http://www.ogf.org/pipermail/dais-wg/2009-May/000287.html [SL] Put the WSDL/XSD for the query spec on SVN on Grid Forge. Done. ---- - Progress, status of: DAIS RDF motivational document Most of last week was a holiday in Japan. Nothing to report. - Progress, status of: query document Some comments have been made on the mailing list from ADMIRE implementing the query spec - mainly typos. - Progress, status of: ontology documents Mario commented on part of the ontology document - picked the entire document as opposed to the inner profile. Passed these on to Miguel. Miguel will have a look and produce an updated version of the document. - Planning No OGF sessions. Next call on 21 May 2009. +-----------------------------------------------------------------------+ |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/ | +-----------------------------------------------------------------------+ -- The University of Edinburgh is a charitable body, registered in Scotland, with registration number SC005336.

Feedback about the current RDF(S) query spec [RV: problems using the WS-DAI-RDFS specification]
by Miguel Esteban Gutiérrez 07 May '09

07 May '09

Hello everybody, I finally managed to talk to the developer who is implementing the RDF(S) query spec. In short, he doesn't know if the version available in the forge is up-to-date and reliable, as he found errors in the annexes (which in the end provide a "computable" API of the specification) that in case of being under development would not be there. Anyhow, he also mentions that most of the errors and typos can be corrected easily, just by inspecting the WSDL files. Find attached his comments and suggestions. Cheers, Miguel -----Mensaje original----- De: Carlos Buil Aranda [mailto:cbuil@fi.upm.es] Enviado el: martes, 05 de mayo de 2009 15:44 Para: Miguel Esteban Gutiérrez Asunto: problems using the WS-DAI-RDFS specification Hello Miguel, Here comes a short list with the problems I had when I worked with the WS-DAI-RDFS specification. The first problem I saw is that the last version of the specification document is from July 2007. So I suppose it is not updated to the latest version of the specification but I do not know for sure. Another problem is that the WSDL and XSD files are in the annex of the document. I think it would be better to have separate document so these files can be validated. The next problem is regarding namespaces. Due to a .doc document cannot be parsed by a WSDL checker some errors appear. I saw errors in the namespaces at the beginning of the WSDL document, typos in operation names (such mazOccurs=unbounded) or typos when referencing messages down in the port types section. Finally I managed to make all work but I needed a bit of time for solving all the mistakes. Cheers, Carlos

DAIS WSDl/XSD
by Mario Antonioletti 02 May '09

02 May '09

Folks, Have put the wsdl and xsd for the WS-DAI/WA-DAIR/ WS-DAIX specs up on grid forge - should have done this a long time ago. The wsdl/xsd and a couple of xml examples should correspond exactly to what is on the specs. Let me know if this is not the case. The SVN URL to access this is: http://forge.ogf.org/svn/repos/dais-wsdl-xsd and you will find the stuff in trunk. Would be good if the RDF folks could put the wsdl/xsd there too in a subdirectory. You can also get to this from the Grid Forge project page: http://forge.gridforum.org/sf/projects/dais-wg Source Code->dais-wsdl-xsd Currently does not allow anonymous access (not sure how to change this as yet). To check out: svn checkout --username YourUserName http://forge.ogf.org/svn/repos/dais-wsdl-xsd Let me know if you have any questions, Mario +-----------------------------------------------------------------------+ |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/ | +-----------------------------------------------------------------------+ -- The University of Edinburgh is a charitable body, registered in Scotland, with registration number SC005336.
