This is the discussion group of the members of American Society of Indexers' Taxonomies & Controlled Vocabularies Special Interest Group. These are individuals with an interest or background in indexing who create or edit taxonomies for external clients or audiences, either as freelancers/consultants or as in-house developers of taxonomies/controlled vocabularies for externally offered (sold) information sources. Individuals who are not members of the SIG or the American Society of Indexers but are regularly involved in taxonomy/controlled vocabulary work may join the discussion group on a case-by-case basis, approved by the moderator. For advice on taxonomies, however, please join the Taxonomy Community of Practice Group instead.
