LAC Releases Government of Canada Core Subject Thesaurus
From the post:
The government of Canada has released a new downloadable version of its Core Subject Thesaurus in SKOS/RDF format. According to Library and Archives Canada, “The Government of Canada Core Subject Thesaurus is a bilingual thesaurus consisting of terminology that represents all the fields covered in the information resources of the Government of Canada. Library and Archives Canada is exploring the potential for linked data and the semantic web with LAC vocabularies, metadata and open content.”
When you reach the post with links to the vocabulary you will find it is also available as XML and CVS.
There are changes from the 2009 version.
Here’s an example:
| old form | new form | French equivalent |
| Adaptive aids (for persons with disabilities) |
Assistive Technologies | Technologie d’aide |
Did you notice that the old form and new form don’t share a single word in common?
Imagine that, an unstable core subject thesaurus.
Over time, more terms will be added, changed and deleted. Is there a topic map in the house?
