SKOS:
Simple Knowledge Organization System

2. Knowledge Organization Systems
“The term knowledge organization systems is intended to encompass all
types of schemes for organizing information and promoting knowledge
management. Knowledge organization systems include classification
schemes that organize materials at a general level (such as books on a
shelf), subject headings that provide more detailed access, and authority
files that control variant versions of key information (such as
geographic names and personal names). They also include less-
traditional schemes, such as semantic networks and ontologies.”
