[Objectbridge-jdo-dev] jdo metadata

Do the .jdo files need to be accessible at runtime or just at enhancement time?  Sounds like just at enhancement time and even that's optional (will do default action if no jdo file found).

According to the spec they are required at runtime and enhancement
time.  They are needed at enhancement time to (at the very least)
specify which files are persistent.  I'm not sure why they're needed at
runtime, but the spec says they are.

you are right, they are needed at runtime, too. For example, if the 
schema-mapping is stored in these files, the jdo-implementation obviously 
needs it. Even if no vendor-extensions are present, they have to be present 
to know some settings for persistent fields, for example, whether to store 
embedded or not, whether a field is transient (not to be confused with the 
java keyword with the same name), transactional or persistent, of which 
classes collection members are and so on...
