From Craig L Russell <Craig.Russ...@Sun.COM>
Subject Re: JDO TCK Conference Call Friday, July 20, 9 am PDT
Date Fri, 20 Jul 2007 22:31:55 GMT
Attendees: Michelle Caisse, Matthew Adams, Michael Bouschen, Craig  


1. Annotations update Craig checked in some changes to annotations  
that included changing String[ ] embedded to Embedded[ ] embedded.  
This caused the enhancer to fail. Other changes pending will also  
make the enhancer fail: removing @Field and @Property, replacing them  
by @Persistent. These changes were outlined in the message from Craig

The only reason to have PersistenceModifier at all is to make it  
possible to say @Persistent 
(persistenceModifier=PersistenceModifier.NONE) or @Persistent 
(persistenceModifier=PersistenceModifier.TRANSACTIONAL). It can be  
removed without loss of functionality.

The spec should note that @NotPersistent maps to persistence- 

recursionDepth needs to be added to @Persistent so it can be used  
instead of @FetchField in @FetchGroup.

Maybe we should remove @Persistence type() because types() covers it.  
Perhaps we should rename the element to allowedTypes, or  
requiredTypes or boundedTypes, permittedTypes(), subTypes(),  

AI Craig update the proposal; attach a patch to a new JIRA; call for  
a vote

2. Other issues

Interesting application that might apply to JDO. Domain Driven  
Design, Eric Evans. Persistent objects that have collaboration logic  
for relationship handling but also have some business logic. Content  
management application. Planned vs. actual pattern. Detached object  
launches a thread and notifies a listener of a state change. The  
listener attaches the object to the database and updates the database.
