I wouldn't mind if we add methods for ClassDescriptor lookups to the  
DataObjectUtils. BTW PersistentObject defines 'getObjEntity' method.  
I'd say we replace that with 'getClassDescriptor' and move it to a  
utility class.

While we are at it, maybe rename DataObjectUtils to something more  
appropriate and shorter. CayenneUtil? Cayenne? ("Util" is already  
taken, and I'd rather it identify the origin of the framework).

I sort of like calling it just "Cayenne" (for the same reasons of user  
simplicity), but then it implies this is a central class in the  
framework, and has more than just lookup-by-pk or give-me-metadata  
methods.

I tend to not like abbreviations for the most part (a little peeve of
mine -- I fall into the "software is meant to be read, not written"
camp), so I'd vote for something more like "Cayenne" in the current
org.apache.cayenne.util package.  Simple, direct, and to the point.

+1 makes the most sense (to me at least) given it reflects the flavour of the interface to which these objects belong whether server-side or not.

Cayenne or maybe PersistentUtils - because it will work with all types of
classes (or at least those that implement Persistent).

CayUtils? I'm good with Cayenne, too.
