I guess the issue is that the person might change email addresses. But I
suppose a once-owned-address property might work if they ever generate a
foaf (I doubt they ever will anyway).

I assume you're using an old version of RDFPic as the current version
lets you describe the people in the file in RDF aswell as just the

Also, tools exist to do stuff with this information, converting it into
SVG mostly...

I don't use RDFPic, but my tool (
http://jibbering.com/svg/AnnotateImage.html ) produces similar RDF (yes
we interoperate...) and then I have various tools which take this RDF and
produce various outputs, others not mentioned that page are
http://jibbering.com/2002/8/img-desc.svg (or the talking version
http://jibbering.com/2002/9/talking.html ) and
http://jibbering.com/rdf/codepiction.1 all using the base RDF.

To identify the people you can just not give them an email address, and
there's no problem (well it would be useful if you could as otherwise we
can't know that the person in one picture is the same as the person in
another) e.g.

<foaf:nick>freddie the frog</foaf:nick>
<foaf:name>Fred Bloggs</foaf:name>

You don't need an actual URI for the person.
