Meaning of Web Signs in RDF and OWL
Non-editorial revisions of RDF Concepts took out all sections concerning "Social Meaning", "assertion", and "propositional attitudes".

What is keyword?
What is keyword? - A Word Definition From the Webopedia Computer Dictionary, """ In programming, a keyword is a word that is reserved by a program because the word has a special meaning. Keywords can be commands or parameters. Every programming language has a set of keywords that cannot be used as variable names. Keywords are sometimes called reserved names."""
Example Definition of Terms
State of Missouri Standard Specifications for Highway Construction Section 101 is a list of terms and the required interpretation of those terms within the context of a highway construction specification.

Re: 2.3 URI Ambiguity from Tim Berners-Lee on 2003-12-02 (www-tag@w3.org from December 2003)
Codestriker: Resources
Sometimes Meaning is More Important than Reasoning
Interpreting a sign or symbol, in this case a URI, to get the signified, or the referent, is a separate and distinct operation from any reasoning done with that symbol. In some cases, reasoning is secondary and interpretation is more important. Out of all the valid possible interpretations of a symbol, in a given context or use case, how do you fix one interpretation above all others, in the targets you wish to communicate the meaning to?
Further Examples of Stipulative Definitions
Many specifications refer to RFC 2119 with the words, "The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED",
"MAY", and "OPTIONAL" in this document are to be interpreted as described in RFC 2119." How could we say this about URIs in an RDF document?
See also Tim Berners-Lee's example of ambiguity. The URIs are not at all ambiguous in the context of his email, but they are ambiguous in the context of his example in the email.

Semantic Web Meaning is All Social
It seems to me that semantic web meaning is all social. Unless we believe that even our most powerful computers really understand the meaning of the symbolic terms that they manipulate. If you do believe that, then let me answers to these questions: How does your software agent encode the meaning of a symbolic term (URI) into an RDF graph?
