Re: PROPOSED RESOLUTION: use dcterms for the maker element and rename to creator

There's another consequence of this I've just realised (I'm searching 
and replacing...). The current specs point to foaf:depiction as the way 
to associate a logo with a DR. Alan uses foaf:logo in his Euracert 
vocabulary file [1] (which is better I think than depiction here) but 
losing FOAF from POWDER, at least at the normative level, means we may 
need to create our own logo property.

DC doesn't have a 'logo' property. The nearest is has is description [2] 
which we use for our textual summary but in fact, DC says it can be an 
image as well. To use that would mean we'd have something like

<dc:description>Text here...</dcterms:description>
<dc:description rdf:resource="http://image.example.org/thing.png" />

And then maybe

<rdf:Description rdf:about="http://image.example.org/thing.png" />
   <dcterms:type>image/png</dcterms:type>
<rdf:Description>

Yuk.

The simple solutions that I can think of are:

1. Define our own POWDER-S term wdrs:logo to which <displayicon> maps
2. Leave this out altogether so people can chose their own property. The 
downside of this is that User Agents may be looking for a specific 
property to get a logo to display - hence I'm for option 1.

Phil.
