Propositions of Conventions and Ontologies
for the Resource Description Framework (RDF)

This document was created in May 2000 and is now superseded by
this document on conventions and
this document comparing RDF+OWL with more expressive and readable languages.

To permit or enhance knowledge retrieval and sharing, knowledge providers should follow conventions and re-use common ontologies. Below are some propositions. This page was intended to complement the content of the RDF-DEV Resource Directory.

1. Conventions

• Some Lexical Conventions
  • InterCap Style for Names
  • Singular Nouns for Names
  • Inverse Relations


• Some Structural Conventions
  • Binary Basic Relations
  • Avoid Disjunction or Negation in Statements
  • Precision, contextualization and constraints


• Some Syntactic Conventions and RDF Extentions For Logic
  
  • Universal quantification
  • Collections and intervals


• Mail me for other conventions to be listed here

2. Ontologies (Categorizations)
