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

To permit or enhance knowledge retrieval and sharing, knowledge providers should follow conventions and re-use common ontologies. Below are some propositions. This page is intended to complement the current 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
