[ I meant "is/was" incidentally, it was a typo. ] To back this up: http://en.wikipedia.org/wiki/RSS#History I would have trouble writing a definition of success that excluded RSS circa 2002, more recent formats have muddied the waters a bit, but it's still a very common format. Also, Adobe XMP is serialised externally in RDF/XML (inside a wrapper element), though on the web it's more commonly found embedded in JPEGs and the like. I don't know what syntax is used when embedded - almost certainly not RDF/XML. As an Adobe Lightroom user, I've got something like 100,000 XMP files sitting on various drives. Here's the head of one I pulled at random, 2010/2010-04-03-Regents-St/_D7A3501.xmp: <x:xmpmeta xmlns:x="adobe:ns:meta/" x:xmptk="Adobe XMP Core 4.2-c020 1.124078, Tue Sep 11 2007 23:21:40 "> <rdf:RDF xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#"> <rdf:Description rdf:about="" xmlns:tiff="http://ns.adobe.com/tiff/1.0/"> .... None of this means that I'd hold up RDF/XML as good practice though, I certainly only endured it because of the utility I got from the data, rather than using it out of choice. - Steve -- Steve Harris, CTO, Garlik Limited 1-3 Halford Road, Richmond, TW10 6AW, UK +44 20 8439 8203 http://www.garlik.com/ Registered in England and Wales 535 7233 VAT # 849 0517 11 Registered office: Thames House, Portsmouth Road, Esher, Surrey, KT10 9AD
