Controlled Vocabularies

By Stephen Downes - Stephen's Web. Controlled Vocabularies
Canada maintains a registry of controlled vocabularies for use in Dublin Core metadata elements. This page links to a wide variety of them, including audience, coverage, format, various subjects, and more. It's a good example of a controlled vocabulary, but may not be useful for everyone, as it is fairly narrowly targeted. And sometimes the choices are odd; in the audience vocabulary, for example, you can specify 'women' as an audience, but not 'men'.
