Often stated questions are "Where can I find an ontology for XY?"
Much more helpful, I think, would be the answer to the question, how to find useful ontologies in general. So, what directories or search engines do you know to find ontologies? Or what are your ideas to make finding ontologies easier?

SKOS is a common data model for sharing and linking knowledge organization systems via the Web. Many knowledge organization systems, such as thesauri, taxonomies, classification schemes and subject heading systems, share a similar structure, and are used in similar applications. SKOS captures much of this similarity and makes it explicit, to enable data and technology sharing across diverse applications.

RDF is a directed, labeled graph data format for representing information in the Web. This specification defines the syntax and semantics of the SPARQL query language for RDF. SPARQL can be used to express queries across diverse data sources, whether the data is stored natively as RDF or viewed as RDF via middleware.

This semantic web tutorial gives a quick tour of RDF, RDFS, SPARQL and Rules. It was designed as a hand-on-keyboard introduction to the basics of RDF model, RDFS semantics for lightweight ontologies, OWL Lite semantics for lightweight ontologies, SPARQL query language for RDF graph bases and production rules for knowledge factorisation in semantic web annotation bases.
