Agenda:
1. Subqueries in JDOQL, followup (Eric, Craig, Michael) It seems that attempts to separate the query from its subquery reduce the functionality, in particular for correlated subqueries. So the "future" idea of creating two query objects and binding one to the other seems not to work. We are now discussing the use of variables to specify the subquery. Since a subquery needs to specify such things as the return type, unique, and candidate class, it seems that the single string query is the best way to specify the value of the variable. AI: Everyone respond to Matthew's email dated June 9.
2. Updates to embedded field, date field selected in owning object (Craig) The consensus is to always return SCO instances that are not associated with FCO instances. So updates to the SCO instances will never appear in the datastore. AI: Michelle will write the test case for JIRA http://issues.apache.org/jira/browse/JDO-382
3. Other issues (any and all) Matthew Adams blogged about JDO and EJB3: http://www.theserverside.com/news/thread.tss?thread_id=40965We need more documentation to make JDO more accessible. One option is to use EJB3 annotations for metadata. JPOX. Address junior Java programmers with some really basic education about persistence. White paper "Persistence for Dummies". Links from the JDO web site to other sources of documentation and some original material. High level describe roles in building JDO applications. We could put some keywords on our web site such as Java Persistence, EJB3, JDO, etc. We could do an analysis of open source benchmarks such as Pole Position.
The JPOX community is looking for more members, and so is the Apache JDO project. We need to brainstorm how to get the two communities to work closer together.
Action Items from weeks past:[Jun 9 2006] AI Martin write up alternative proposal on subqueries (have some way to defer execution of a query and pass the "future" query result to the outer query as a parameter.) Done.
[Jun 9 2006] . Re updates to embedded field, date field selected in owning object. AI everyone who cares: reply to David's reply. AI Craig update the spec with the results of the discussion. AI Michelle update the test case with the spec results. Done.
[Jun 2 2006] Additional query tests are in Craig's workspace. AI Craig: file a JIRA with patches to be reviewed. In progress.
[Jun 2 2006] AI team: go through the open issues and assign relevant issues to the maintenance release. In progress.
[May 26 2006] The spec describes handling of oid fields (application identity) where the field is a persistence capable type. The description says that the type of the oid field must be the same type as the persistence capable class, but actually the type of the oid field must be the type of the oid of the referenced class. AI Craig: update the spec and the wiki change log. In progress.
[Apr 14 2006] AI Craig: update the roadmap for JDO. In progress.[Nov 4 2005] AI Martin: Update Martin's wiki with discusion of JDK 1.5 issues. In progress
[Sep 2 2005] AI: To recruit members, update the web site. Articles on TheServerSide directing attention to the site. T-shirts, logo. AI: Craig write a ServerSide article.
