As another example: Dublic Core defines a 'creator' thus:

<rdf:Property rdf:about="http://purl.org/dc/elements/1.1/creator">
      <rdfs:label xml:lang="en-US">Creator</rdfs:label>
      <rdfs:comment xml:lang="en-US">An entity primarily responsible for
making the content of the         resource.</rdfs:comment>
      <dc:description xml:lang="en-US">Examples of a Creator include a
person, an organisation, or a service. Typically, the name of a Creator
should be used to indicate the entity.</dc:description>
      <rdfs:isDefinedBy rdf:resource="http://purl.org/dc/elements/1.1/" />
      <dcterms:issued>1999-07-02</dcterms:issued>
      <dcterms:modified>2002-10-04</dcterms:modified>
      <dc:type
rdf:resource="http://dublincore.org/usage/documents/principles/#element" />
      <dcterms:hasVersion
rdf:resource="http://dublincore.org/usage/terms/history/#creator-004" />
</rdf:Property>

"dc:creator" doesn't seem to be a 'document' but it might be an Information
Resource?

TimBL suggests that such URIs (non-#) be reserved for InformationResources
[1] which seems to be a reasonable position at face value. My questions are:

1) May Pat Hayes' oak tree be an InformationResource if when I assign it an
HTTP URI, it returns image/jpeg representations? [2]
2) Since I maintain several websites on which there is some information
about me (and other things), can I consider myself an Information Resource?
(i.e. the dc:creator for the representations of the various resources
accessed on my site [3]
3) What are the defining characteristics of Abstract Resource's such that
they are disjoint from Information Resources -- of course aside from the
fact that one is refered to by a URIref -- I mean in the process of
considering whether to assign a resource an HTTP URI or a URIref -- how
ought I decide?
