Re: Semantic Layers (Was Interpretation of RDF reification)

John, Leonid and Andrian,

To summarize our debate about the matter of semantic layers, please see how the components of real RDF, or World Description Framework (WDF) may look (comments and modifications are welcome).

<WDF> :: = <SUO|UFO|ONTAC> <Semantics> <Pragmatics> <Syntax>

<SUO|UFO (entities, things, beings)> :: = <fundamental classes (substance, quantity, quality, process> < individuals> <properties> <relationship> | <axioms> <rules> <EOL>

<Semantics> :: = < signs> < constructs> < entities> <EOL>

<Pragmatics> :: = <agent (mental states)> <utterance> <understanding (communication)> <EOL>

<Syntax (signs, formation and transformation rules> :: = < RDF> | <N3> < OWL>|... <EOL>

A unifying ontology like Standard Upper Ontology or Unified Framework Ontology or ONTAC makes the largest meaning context (or the universe of discourse) involving major kinds of hierarchically ordered extralinguistic entities, also including psychological factors as mental intentions, agent profilespeech acts and contents, interaction, human actions, social and environmental phemonema.


John, 

Tried to adapt on the fly your proposed BNF's syntax, hope missed nothing essential and the punctuations would be read by the email program. As i understood, the idea of this rules come from a syntactic reading of the whole/part relationships by considering a nonterminal symbol as standing for a complex entity sequentially divided into parts and subparts. Very interesting.

with respects to all,

    should be tailored to the semantics and the pragmatics.

  It seems that English** -- or as close as we can get to it computationally -- fits your requirement.

  What do you think?
