Yahoo has been working on RDF for a long time, at least from when a key RDF community guy, Dave Beckett, was hired in 2005. Now it is out of the box what they’ve been playing with . A great new mashup tool called yahoo! pipes allows you to create your own mashups by combinding data from various sources as flickr, deli.cio.us and more.
Most interesting is the fact that you can combind it with RDF! This allows any source to be included as long as you allow your data to be exposed in RDF. What innovation this will create is beyond my imagination, but I’m sure it will be huge! I’ll be back here with some examples of how RDF can be used in this tool, in the mean time why don’t you have a look yourself.
