[Shotwell] MWG composite functions & gexiv2

[Alan Pater <alan pater gmail com>]

I have been talking with Jim Nelson about adding composite functions
to gexiv2. These would be based on Metadata Working Group guidelines
with the addition of a couple of commonly-requested formats.

   https://bugzilla.gnome.org/show_bug.cgi?id=712429

I can do a lot of the grunt work and testing, but need a hand with
some of the conversions, from xml for example. Who would like to
volunteer to give me a hand?

I think it makes sense to do this work in gexiv2, that way all the
individual applications don't have to maintain duplicate code for
these functions themselves. And by abiding to MWG standards, everyone
doesn't have to reinvent the wheel and come up their own set of common
metadata properties.

Here is a link to the MWG Guidelines:
http://www.metadataworkinggroup.org/pdf/mwg_guidance.pdf

My thoughts are to also include support for reading proprietary
metadata from ACDSee, as there appears to be a lot of requests from
users of that Windows app to migrate to a Free Software alternative.

Volunteers?

Cheers,
Alan
