Subject Minutes: JDO TCK Conference Call Friday, June 5, 9 am PDT
Date Fri, 05 Jun 2009 19:24:45 GMT
Attendees: Michelle Caisse, Michael Bouschen, Craig Russell

Agenda:

1. JDOQL & Querydsl: looks interesting, along the lines of JPA except  
JPA uses Java 6 APT whereas it looks like Querydsl uses a static  
preprocessor. Not much of a difference; Querydsl could use the APT  
approach as well. The big advantage in both approaches is compile-time  
checking.

Looks simple at first glance. But what does it look like with more  
complex queries like joins, projections, collection navigation, maps,  
subselects, etc.? How well does it cover the JDOQL query space?

2.  Other issues

Metadata API changes to update method names and change interface name  
from ComponentMetadata to TypeMetadata. Patches type-2.patch and lower- 
case-d-in-metadata.patch are ready to go. Request DataNucleus folks to  
review and commit when they are ready.

All JDO 2.3 JIRAs have been assigned owners. To improve the schedule,  
feel free to volunteer to take already owned items.

Action Items from weeks past:

[May 25 2007]  AI everyone download the Grails demo from grails.org   
and check it out. Also look at Grails/Groovy ExpandoMetaClass that   
has the magic to avoid reflection and enhancement.

[May 25 2007] AI Matthew Adams prepare a proposal with just the basics  
of schema synchronization with jdo and orm metadata.
