RDF aware user agents since we cannot assume which methods they will be using to discover RDF. On our part (re. our RDF aware user agents), we use all the methods (Content Negotiation, <link />, GRDDL, RDFa, and POSH) when sniffing, which also implies that we take on the burden of normalization. On the part of publishers, I encourage the use of at least one of the RDF exposure methods mentioned above, when known associations between HTML and RDF representations exist. -- Regards, Kingsley Idehen Weblog: http://www.openlinksw.com/blog/~kidehen President & CEO OpenLink Software Web: http://www.openlinksw.com
