This Onomies page is a place to discuss and capture information related to the wikipedia:taxonomy, wikipedia:folksonomy, and Wikipedia:Ontology. Tom Gruber believes these terms follow the format: 1. * Folksonomy (informal, user-defined) 2. * Controlled vocabularies (the user must deploy a set of defined terms) 3. * Taxonomy (Pre-defined terms in which specific terms are subsets of more general terms) 4. * Ontology (A rich set of relationships is mapped out among all the terms)
