I have created a
PNG[PNG] icon
for pointing at RDF content inspired by the XML icon made by
Dave Winer.
The image contains its own embedded description including the terms
of use as both PNG metadata:
and embedded RDF/XML metadata:
I suggest you use it something like this:
<a href="rdf-content" title="RDF version of the content" type="application/rdf+xml"><img src="rdf.png" alt="RDF" width="36" height="14" border="0"/></a>
Note that RDF's XML syntax has no registered Internet Media Type (MIME type) at present however it probably will be application/rdf+xml based on the hints in [RDFMT1], [RDFMT2] and [XMLMT].
