Al, just a minor point >A 'conceptual scheme' or 'concept scheme' is defined here as: a set of concepts, optionally including statements about semantic relationships >between those concepts. Thesauri, classification schemes, subject heading schemes, terminologies, glossaries and other types of controlled >vocabularies are all examples of conceptual schemes. should read, 'subject heading systems' (NOT schemes) This comes from 'subject heading languages' SHL (a good source for these are "Principles underlying subject heading languages" (Muenchen: KG Saur, 1999) When applied SHLs become 'systems' (e.g. LCSH system, RSWK system, RAMEAU system, EMBM system, SIPORBASE system etc.) and systems contain terms. The expression 'scheme' is usually used for languages with symbolic representation and are not normally used in relation to SHLs Also, it seems to be pretty safe to consider 'taxonomy' as a type of classification. But if a link between the two needs to be explicit then "classification (taxonomical) schemes" The main question is whether SKOS implementors also see it as a same type of vocabulary is what needs to be decided... See below a typical example of classification and a typical example of taxonomy Classification (copy/paste from a UDC database) 599 Mammalia. Mammals 599.1 Prototheria (Eplacentalia). Egg-laying mammals 599.11 Monotremata 599.111 Tachyglossidae: Echidnas (Spiny anteaters) 599.112 Ornithorhynchidae: Duck-billed platypus 599.2 Metatheria. Metatherian mammals Taxonomy of animals (the first I found on the web http://www-biol.paisley.ac.uk/biomedia/text/txt_mammal.htm CLASS : Mammalia SUBCLASS : Prototheria Example : Triconodonta *, Monotremata SUBCLASS : Theria INFRACLASS : Trituberculata * INFRACLASS : Metatheria Example : Marsupialia INFRACLASS : Eutheria Aida
