From Craig L Russell <Craig.Russ...@Sun.COM>
Subject Minutes: JDO TCK Conference Call Friday, June 29, 9 am PDT
Date Fri, 29 Jun 2007 16:40:00 GMT
Attendees: Michelle Caisse, Matthew Adams, Michael Bouschen, Craig  

NOTICE: No meeting next week (July 6) unless someone proposes an  
agenda by next Thursday July 5


1. Put all annotations on class, name field within annotation? Craig  
would like to have the ability to put the entire annotation for a  
class on the class, and follow the pattern of xml. This might more  
closely align the xml and the annotations. It would require a change  
to the definition of @PersistenceCapable to allow a list of fields.  
What if you annotate the class with some fields and then also  
annotate a field? AI Craig start a discussion on email

2. Nested embedded annotations? The xml is currently more powerful  
than annotations by allowing embedded embedded fields. The  
annotations need to be extended to permit this. AI Craig start a  
discussion on email

3. Primary key, foreign key annotations? Want to be able to specify a  
key for a subset of annotations. Key, value, join and element. How  
about making them arrays of a type? How about making these  
subinterfaces of a @Constraint annotation? AI Michelle start  
discussion on email.

4. Other issues

JPOX doesn't yet support persistent properties or persistent  
interfaces via annotations. Track this issue via http://jpox.org/ 

Michael made an experiment to see if it's possible to create an  
instance that implements an @Annotation by using anonymous inner  
class. It compiles; more work is needed to see if it's useful.
