Abstract:

This is a brief introduction to the relationships between taxonomies, thesauri and ontologies, and similar ‘things’. It doesn’t contain definitive, scientific definitions, it is a personal interpretation of some fairly complex structures. It aims to give you a fairly clear what these ‘things’ are, so librarians or IT people can’t blind you with science.
