Thank you for your book. I appreciated the read. It left me thinking about the future. While pondering, it occurred to me that The Semantic Web and The Grid would converge.

I did a quick google on it, and came upon this site (and in particular, its brief):
http://SemanticGrid.org/brief

There is actually quite a bit of activity related to this convergence with web services sitting in the middle (what I view as the interactive enabler/aspect of Grids).

As an example, I liked what I saw with respect to the matching of resource with the call for the resources (the job being submitted). An ontology can be created (using OWL) to describe the services being offered which can help a rules engine deterministically select which compute node/service is best suited for a particular job.

Kind regards,
