Re: Alternatives to annotations for metadata?

[Philip Aston <ph...@mail.com>]

Thanks Pinaki - good to now I haven't missed anything.

Couldn't there be an orm-openjpa.xml that mirrored orm.xml, adding vendor
metadata?

Hi Philip,

Yes, possible. Some discussion took place on this issue [1] but the thread
is not currently active. Adding a name-value under a <vendor-extension> tag
in orm.xsd perhaps would have been a straightforward route. I will check
with the JPA Expert Group to ascertain the response to such a request. 
Having a mirrored 'orm-openjpa.xml' would require to match/merge tags for
the same entity, require overwriting rules etc. Doable but non-trivial.
