2. Purpose

This standard adopts the principle of controlled vocabulary for the management of electronic information. The use of controlled vocabulary is necessary to classify and describe information, and to support navigation, searching, information sharing and interoperability goals of Government On-Line (GOL).

More specifically, the standard adopts the Government of Canada Core Subject Thesaurus from the Depository Services Program (DSP) as the default thesaurus to be used by federal organizations. The standard also adopts the Government of Canada Core Subject Thesaurus as the default thesaurus to be used with the Common Look and Feel (CLF) mandatory element "Controlled Subject".

Controlled vocabulary used by the Government of Canada should be registered and publicly available.

3. Application

The Common Look & Feel Standard 6.3 establishes the use of controlled vocabulary for the mandatory "Controlled Subject" metadata element. The Government of Canada Core Subject Thesaurus is the default thesaurus to be used by federal organizations.

Some organizations already use departmental or existing thesauri. In this event, thesauri must be bilingual, comply with the ISO standards 2788:1986 "Guidelines for the establishment and development of monolingual thesauri" and 5964:1985 "Guidelines for the establishment and development of multilingual thesauri", and be registered either with the National Library of Canada or the Dublin Core Metadata Initiative (DCMI). Departmental and/or existing thesauri must be capable of being mapped to the Government of Canada Core Subject Thesaurus.

Alternatively, organizations can use internationally accepted controlled vocabulary lists relevant to them, such as the Library of Congress Subject Headings (LCSH), the Canadian Subject Headings (CSH) or the Répertoire des vedettes-matières de l'Université Laval. Recognized organizations or departments maintain such lists that are registered either with the National Library of Canada or the Dublin Core Metadata Initiative (DCMI).

Only terms from a registered or authoritative source of subject terms can be assigned. Non-controlled subject terms should only be used by the HTML tag "Keywords".

4. Definitions

Controlled Vocabulary:
artificial language used to classify and describe information. It permits the generation of formal representations of documents and enhances information retrieval.
Mapping:
mapping allows correspondences between thesauri, thus allowing users to refine their search by automatically finding the appropriate terms from a thesaurus.
Metadata:
structured data about data used to aid the identification, description, location or use of information resources.
Thesaurus:
a hierarchical list of controlled terms that are used both by indexers to describe information resources and by users to gain access to them. It provides synonyms and related terms to help users identify the appropriate term within their scope of interest. It standardizes the external form and the meaning of index terms, thus ensuring that a particular concept or subject will always be represented in the same way in the index. It makes easier the conceptual navigation through knowledge fields and information retrieval, and reduces redundancy and ambiguity.

5. Qualifications

Nil

6. Implementation

The Government of Canada Core Subject Thesaurus has to remain publicly available. The recommended Government of Canada metadata generator tools and search engines should link to the Government of Canada Core Subject Thesaurus and other registered thesauri.

Other thesauri and controlled vocabulary lists must be made publicly available as well.

On the roles and responsibilities, the National Library will maintain this standard and insure the registration of other thesauri and controlled vocabulary lists.

Depository Services Program, Public Works and Government Services Canada will maintain the Government of Canada Core Subject Thesaurus.

7. Specifications (reference to external standard adopted)

This standard adopts ISO standards 2788:1986 "Guidelines for the establishment and development of monolingual thesauri" and 5964:1985 "Guidelines for the establishment and development of multilingual thesauri". This means that any thesauri used within the Government of Canada should comply with these ISO standards.
