￿ identifies : An OWL Object Property. The relationship between a URI
and a resource. It can be functional as one should “assign distinct URIs to
distinct resources” although some users of this ontology may wish to not use
this constraint and so use the refersTo property (Jacobs and Walsh 2004).

￿ refersTo : An OWL Object Property. The relationship between a resource and
another resource where the former may be immediately causally disconnected
from the latter but still 'stand in' for it in a syntactic expression. Note that
reference in the logicist position is an aspect of an interpretation of the syntax

a meta-property that attempts to make explicit the intended interpretation of an
agent.

Information Resources
There is a controversial sub-class of Resource outlined in AWWW known as
'information resources.' The AWWW defines the notion of information resource
as “a resource which has the property that all of its essential characteristics can be

but concrete individual URIs are instances of this class and could be any URI.
