E-science is touting the juxtaposition of grid technology and the semantic web to form the
semantic grid which will serve as the basis for future collaborative scientific explorations . See the book Grid "Computing: Making The Global Infrastructure a Reality" by Fran Berman, Anthony J.G. Hey and Geoffrey Fox. Tony Hey worked with Feynman at Caltech and is also the editor of Feynmans excellent books on computation

Grid toolkits like the Globus toolkit has been around for some time. Condor is often used with BeoWulf Linux clusters to provide the foundation for the matrix infrastructure.

W3C announced the RDF and OWL recommendations in January 2004 and together with web services this will be the basis for the Semantic Web. There is a lot of tool making happening and especially around the enaction of the logic. Tim Berner Lee did some early experiments with a Python implementation of CWM and now there are tools implemented in higher-level functional langages like Swish which is written in Haskell.
