These properties are used to state mapping (alignment) links between SKOS concepts in different concept schemes, where the links are inherent in the meaning of the linked concepts.
- skos:mappingRelation - used to state mapping connections between SKOS concepts in different concept schemes
- skos:closeMatch - used to link two concepts that are sufficiently similar that they can be used interchangeably in some information retrieval applications.
- skos:exactMatch - used to link two concepts, indicating a high degree of confidence that the concepts can be used interchangeably across a wide range of information retrieval applications
- skos:broadMatch and skos:narrowmatch - used to specify a hierarchical link between concepts. These two properties are inversely related to one another. skos:broadMatch is a sub-property of skos:broader and skos:narrowMatch is a sub-property of skos:narrower.
- skos:relatedMatch - used to state an associative mapping link between two concepts.
