I've pushed out my old metadata branches to:

http://cgit.freedesktop.org/~ajohnson/cairo/log/?h=metadata

http://cgit.freedesktop.org/~ajohnson/cairo/log/?h=metadata.old

I can't find the mailing list discussion for this. Maybe it was on IRC.
At the time there was no consensus reached on an API for metadata.

My preference would be for the API on the metadata.old branch. The
Dublin Core stuff in the metadata branch could always be added later if
there is demand for it.
