- Comment
- The range of skos:altLabel is the class of RDF plain literals.
- skos:prefLabel, skos:altLabel and skos:hiddenLabel are pairwise disjoint properties.
- Definition
- An alternative lexical label for a resource.
- Example
- Acronyms, abbreviations, spelling variants, and irregular plural/singular forms may be included among the alternative labels for a concept. Mis-spelled terms are normally included as hidden labels (see skos:hiddenLabel).

- skos:closeMatch is used to link two concepts that are sufficiently similar that they can be used interchangeably in some information retrieval applications.

- Definition
- skos:exactMatch is 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:exactMatch is a transitive property, and is a sub-property of skos:closeMatch.

These concept mapping relations mirror semantic relations, and the data model defined below is similar (with the exception of skos:exactMatch) to the data model defined for semantic relations. A distinct vocabulary is provided for concept mapping relations, to provide a convenient way to differentiate links within a concept scheme from links between concept schemes. However, this pattern of usage is not a formal requirement of the SKOS data model, and relies on informal definitions of best practice.
