Howdi.
I spent some time with the Metadata tool, and finally
implemented a prototype that makes flexible Metadata possible.
I still have some problems (at least the catalogability for things not
implemented by Dublincore isn't working) but it's working, and full
backwards compatible.
What I did:
- Modify the list of Elements that are metadata
- Store the Metadata not in the object itself, but in a bag, that's
attached to the object (PersistentMapping for the ease ...)
- Created a new policy mechanism that builds up on "Validators".
Every Element is associated with a validator, that cares for e.g.
a Vocabulary, a Date Type and such things. I implemented
Validators for Vocabulary, DateTime and String.
- Automatic form generation for the edit_metadata_form (zpt skin
only)
This is a prototype that shouldn't be used with *any* existing
installation. Get a CMF 1.3, apply the patch, then create the portal
and play around.
Who was asking for the proof-of-concept? Has it been you, Tres? Please
check this out, and tell me what you think.
(Yes, the code isn't very clean, and maybe not very self explanatory,
but it should be usable out of the box in a portal ...)
Regards
Christian
