Thank > heaven THAT didn't happen ;-) ! You might be thinking of http://archive.ifla.org/documents/libraries/cataloging/metadata/dublin3.htm "On Information Factoring in Dublin Metadata Records", C. M. Sperberg-McQueen, 17 April 1996. also at http://dublincore.org/documents/2001/03/19/info-factoring/ "This document describes some problems in the interpretation of metadata records which contain repeated fields, repeated field groups, or references to other metadata records. The semantics of repeated fields and groups (and, equivalently, of references to other metadata records) are described using sentential logic, and a proposal is made to specify the interpretation of repeating groups using the disjunctive normal form of corresponding logical expressions." Or for the Lisp-y tradition, the RDF ancestor http://www.w3.org/TR/NOTE-pics-ng-metadata "This document introduces an model for representing metadata, and a syntax for expressing and transporting metadata based on this model." (nearby: http://www.w3.org/PICS/NG/ cites both...) My colleagues at vu.nl btw make a lot of use of Prolog with RDF, eg. nice work at http://www.swi-prolog.org/web/ClioPatria/whitepaper.html but in general, I'm quite happy that RDF allows folk to make use of tools from the KR tradition, but doesn't require it... cheers, Dan
