[Yanel-dev] Metadata Interface for resources

[Michael Wechner]

Hi

I recently had a discussion that we should have a generic interface for 
tagging resources, for example saying this resource instance is
about "shoes and clothes", such that search engines and other data 
analyzers will have it simpler, but also such that if a
resource is Versionable, one can have different tags for each version, etc.

We already have a bugzilla entry

http://bugzilla.wyona.com/cgi-bin/bugzilla/show_bug.cgi?id=7170

but AFAIK we have never really discussed how such an interface should 
look like, for example

MyResource implements MetadatableV1

MetadatableV1#setTags(String keywords)

MetadatableV1#getTags()

but also something to allow arbitrary extensions without having to 
create new versions of this interface, e.g.

MetadatablV1#setMetadata(String key, String value)
MetadatableV1#getMetadata(String key)

but also maybe use DublinCore.

WDYT?

Thanks

Michael
