BS 8723: Structured vocabularies for information retrieval – A guide to this new standard was offered and key questions were asked about it concerning challenges and opportunities. Should we think of BS 8723-2 as needing rigorous implementation, or is it more of a springboard from which to launch new ideas? Facet analysis practice as developed by the CRG – will it come of age, or has the genie already left the bottle? Is it useful/practical to apply a tight definition to “taxonomy”? Which offers greater benefit: one exchange format for all applications, or a choice of formats, supported by transforms between them? Format extension: should it reach towards ontologies, or towards classification schemes, or what? And what about folksonomies – is there any benefit from considering them at all in BS 8723 or ISO 25964?
