Query by Criteria

[Kevin Roll]

Are there any plans to add Query by Criteria to the JDO standard? I'm  
referring to a programmatic API to build queries, similar to what  
Hibernate already has and JPA is planning to add.

If not, does anyone know of another route to achieving this  
functionality? Are there any libraries that can be layered over JDO to  
get this? Should I write my own?

Thanks for any insight.
