Keywords can serve as additional access points to assist discovery and retrieval.

Keywords are used to:

Improve search results by providing words that may be used to look for a resource but which do not appear in the title, description, or other metadata fields. This might include acronyms and subject synonyms.
Group together resources with similar subject matter. In the Government Data Catalogue, keywords appear as clickable links that, when clicked, will retrieve all other records that contain the same keyword.
Keywords should be entered in the plural form, except for abstract concepts or entities that cannot be counted. (E.g. exports, royalties, births, trade)
Do not enter variant spellings of a word as keywords. Only the accepted spelling of a word should be included.
Do not use abbreviations; spell out the keyword in full.
If entering acronyms, also include the full form of the acronym as a keyword (e.g. OHS, Occupational Health and Safety).
Enter keywords in lower case, except for proper nouns (e.g. public libraries, Calgary Public Library).
Do not use ampersands in keywords; use the word ‘and’ instead.
Nouns and noun phrases are preferred over verbs (e.g. fermentation not fermenting)
Special characters, such as accent marks, should be included as long as they reflect common usage (e.g. Métis).
