Namespace:

The info Registry provides a mechanism for the registration of public namespaces that are used for the identification of information assets.  The Terminology Services Project Terminology Services Project has registered the kos namespace, for use by OCLC Research, for knowledge organization schemes (kos) used by libraries, museums, archives, historical societies, professional associations, and other communities. 

Status:

Registered on 07 June 2004, pending approval by the info URI registrar. 

Description:

The kos identifier provides a mechanism for identifying knowledge organization schemes and the concepts used in those schemes. 

The kos identifier has two elements:

  • scheme
  • concept

The scheme element identifies the knowledge organization scheme being used and the concept element identifies a concept within a given scheme. 

The syntax for the scheme and concept identifiers:

info:kos/scheme/«code»/«expr»/«lang»
info:kos/concept/«code»/«id»
«code»

The «code» in the identifier is required and used to identify a given knowledge organization scheme. 

«expr»

The «expr» in the identifier is optional and specifies the edition name, edition number, or the publication date of the knowledge organization scheme. 

  • When «code» is 'gsafd', use the expression values located here
«lang»

The «lang» in the identifier is optional and specifies the language of the intended audience for the knowledge organization scheme. 

«id»

The «id» in the identifier is required and specifies the unique identifier assigned to a concept by the creator, publisher, or maintainer of the knowledge organization scheme. 

  • Use the unique identifier assigned to the concept by the creator, publisher, or maintainer of the knowledge organization scheme.
