http://esw.w3.org/topic/RdfThesaurus Issue 7 - Thesaurus Linking vs. Thesaurus Mapping There are two distinct situations. Thesaurus Linking: An indexer wants a thesaurus for subject-based indexing of their collection. They find no one thesaurus offers adequate coverage, but a combination of two or more thesauri does. So they want to create and use a hybrid thesaurus. Thesaurus Mapping A collection has been indexed with concepts from thesaurus A. A user wants to search this collection, but using concepts from thesaurus B. Thus some mechanism is required for either transforming the query or transforming the index. The purpose of this issue is to distinguish these two scenarios. If we use the same mechanism for both linking and mapping, there is a lot of scope for confusion. Alistair Miles.
