Hello, If we had an RDF serialization of workflows then querying them for info like processor frequency would be quite easy using SPARQL. We could store all the workflows in an RDF repository and reason/query over them all to find all manner of interesting things. You could also combine repositories from different peoples tavernas and make the same queries over much greater amounts of information. This would also make the 'semantification' of Taverna much simpler.
