While I do indeed claim the right to declare the use of
a word to local to myself or a message, in fact in this case
I think my use is consistent with the use in the RDF
community, and the RDF Model and Syntax Specification
which, as a W3C Recommendation, has a certain following.
So the Community of Interpretation in this case is fairly large.

My tendency is to give respect to different incompatible
communities of interpretation, of varying sizes, as I feel that
the interaction of many different communities of many sizes
is essential to society.

These messages, though are specifically within the www-rdf-logic list
which is a (relatively) well defined community.  It has a web
address
http://lists.w3.org/Archives/Public/www-rdf-logic/
which explicitly links it to
http://www.w3.org/Metadata/
and so to http://www.w3.org/RDF/
http://www.w3.org/TR/REC-rdf-syntax/
which defines RDF and says,

"In order to express this fact to RDF, we have to model the original
statement as a resource with four properties. This process is formally
called ~reification~ in the Knowledge Representation community. A model of a
statement is called a ~reified statement~."
