[Device APIs Requirements] Input to Gallery API

Here is some input to the Gallery API requirements for next week:

Re "must expose metadata about the gallery's content items (copyright,
author, media-dependent information, etc.)" and "Issue: Exposing
metadata is tricky, often giving a choice between creating an endless
ontology or building an open-ended system that guarantees no
interoperability.": 

Similar to the ability to discover the supported fields for contacts
etc, this can be addressed by enabling the webapp to discover supported
metadata. Metadata vocabularies are still evolving but there are some
items that are being adopted widely, defined through namespaces to
ensure interoperability at least in terms of what the metadata item is
supposed to represent. All that the gallery API needs to do is enable
the discovery of the supported metadata. 

Thus I propose the requirement: "must enable discovery of the supported
metadata attributes, including the attribute name and its declared
namespace, if any.".
