OGP, for example, can be considered to be a conjunction of filtered triples (ignoring any triples that don't have a predicate in the OGP namespace), and ignoring particular elements (in XPath terms, '/html/body', '/html/head/*[not(self::meta)]'). Of course the current Facebook implementation doesn't implement RDFa fully - it seems to ignore prefix-to-URI mappings and imply meaning from the CURIE prefix. The subsetting document is guidance for how consumers like Facebook could upgrade their parsers to handle RDFa correctly, while still restricting themselves to consuming the subset they desire. -- Toby A Inkster <mailto:mail@tobyinkster.co.uk> <http://tobyinkster.co.uk>
