SKOS, RDF or OWL
-[John 20070205] why are we selecting these. Do we have more choices ?

Metadata standards provide for the creation of "formal metadata" with consistent collection criteria, terminology and structure.

Ontologies as an Organizational Aid

swatson — Fri, 29 Feb 2008 16:54:00 -0800

Ontologies can help organize information about a topic domain, either within a data system or across different data systems. They can achieve this because of the basic features of ontologies. These features:

Semantic Mappings

graybeal — Tue, 27 Nov 2007 16:58:00 -0800

Introduction

When creating mappings among terms, a common and potentially tricky problem is deciding what relationships to use. The most common relationship, "is the same as", is usually too narrow to satisfy the needs of the mapping organization. What, then, is a good set of basic relationships to use when mapping vocabulary terms?
