Shared-metadata-spec

[Ilmari Heikkinen]

Hi,

Some questions on the shared metadata spec[1], is
this the place to ask them?

First, thank you for the spec, it made my life a lot easier.

Second, is the spec still alive, or should I use something else?

Reason I'm asking is because I'm working on a metadata
extraction app[2] which integrates the output of a dozen
different extractor programs and outputs metadata conforming
to the shared-metadata-spec.

And, well, the shared metadata spec seems to be a bit
incomplete. For one, there's no "Video"-namespace. I've added
some ad-hoc fields to the other namespaces as well, you can
see the list of additions below[3].

One more thing, File.Format uses shared-mime-info as the
backing ontology. Is there one for Audio.Codec and Video.Codec?
