[ 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.
