1. Background

"NISO Z39.19: Standard for Structure and Organization of Information Retrieval Thesauri," by Jessica L. Milstead (From: Proceedings of the Taxonomic Authority Files Workshop, Washington, DC, June 22-23, 1998) http://research.calacademy.org/taf/proceedings/milsteadtaf.html.
Good basic discussion about standard thesauri, plus some links to available tools for creating and maintaining vocabularies.

2. Beginning steps

  • a) Define a scope and purpose for your vocabulary
  • b) Determine how many vocabularies you need
  • c) Determine whether and how to use hierarchies

3. Longer-range planning issues

  • a) Stability (site)
  • b) Maintenance organization
  • c) Creating definitions
  • d) Accessibility to others (schemas, registry)
  • e) Planning for change

Other issues

Other things which the document should cover:

  • A list of standard type encoding schemes, and guidance on how to encode types using these lists suitable for non-cataloguers to understand
  • The difference between dc:type and dc:format and what information to encode in each
  • Best practice guidance on choosing a type from DCMI Type Vocabulary as well as a domain-specific subtype
