Fibre FRBRisation

Those not immersed in the world of cataloguing may not have heard of FRBR (Functional Requirements for Bibliographic Records) but you will. FRBR is an integral part of the Resource Description and Access-based cataloguing standard that is set to replace AACR2. And those not immersed in the world of yarn and fibre may not have heard of Ravelry - an extensive database and integrated social network for knitters, crocheters and spinners, but this popular network is actually a brilliant example of cataloguing/ describing, user contribution, and intelligent system design working together to create a useful, educational, and most importantly well-used (1,489,124 users to date) resource in the FRBR mould.
