Bob, On the web and in print you'll find lots of essays, blogs, articles etc setting out the authors' views on the differences between these vocabulary types, but the only standard I am aware of that attempts to isolate the types in BS 8723 Part 3, which is still in draft. Although this standard is attempting to set out the differences clearly for humans to understand, it does not (certainly not yet) include any advice on how to make a declaration of the vocabulary type for machine-readable purposes. And there is another practical difficulty. While it should be possible to give separate descriptions of what is a thesaurus, what is a classification scheme, subject heading scheme, etc., in practice people have a habit of blurring the boundaries in the vocabularies they are developing. Thus, for example, some subject heading schemes and classification schemes are adding thesaural features. And not everyone follows best practice while developing their scheme. I'm not sure how we can achieve regulated clarity. All the best Stella ***************************************************** Stella Dextre Clarke Information Consultant Luke House, West Hendred, Wantage, Oxon, OX12 8RR, UK Tel: 01235-833-298 Fax: 01235-863-298 SDClarke@LukeHouse.demon.co.uk ***************************************************** -----Original Message----- From: public-esw-thes-request@w3.org [mailto:public-esw-thes-request@w3.org] On Behalf Of Bob Mulrenin Sent: 21 February 2007 11:11 To: public-esw-thes@w3.org Subject: general type of controlled vocabulary Dear all, We are planning some open source components and there are a couple of general issues and I would appreciate your feedback. What is the best practice for declaring the type of controlled vocabulary as either either thesaurus, taxonomy, classification scheme, subject headings, folksonomy, etc ? Hopefully referencing a standard vocabulary of these types (?) It would help to be consistent with others and so that the tools can adapt the management and presentation features, as well as offer services to external apps.... <skos:ConceptScheme rdf:about="http://www.ukat.org.uk/thesaurus"> <dc:type>http://..../thesaurus</dc:type> thanks for any input regards, bob
