SKOS (Simple Knowledge Organization System) is a model for expressing knowledge organization systems in a machine-understandable way, within the framework of the Semantic Web. The SKOS Core Vocabulary is an RDF application. SKOS Core provides a model for expressing the basic structure and content of concept schemes, including thesauri, classification schemes, subject heading lists, taxonomies, terminologies, glossaries, and other types of controlled vocabulary. This article provides some examples for using SKOS and discusses the general principles of building such knowledge bases.

- Knows Simple Knowledge Organization System, or SKOS (2009), an RDF vocabulary for expressing concepts that are labeled in natural languages, organized into informal hierarchies, and aggregated into co
- Understands that in a formal sense, a SKOS concept is not an RDF class but an instance and, as such, is not formally associated with a set of instances ("class extension").
- Understands that in contrast to OWL sub-class chains, hierarchies of SKOS concepts are designed not to form transitive chains automatically because this is not how humans think or organize information
- Understands that SKOS can express a flexibly associative structure of concepts without enabling the more rigid and automatic inferences typically specified in a class-based OWL ontology.
