On a slightly different note, I was wondering if the current validation functionality in workflows, supports semantic validation of ports? If not, that would be a useful addition, especially if the default services were already semantically tagged. This would make it possible to suggest mappings between ports in bulk, as opposed to the more time-consuming port-by-port mapping that you must do now.
Semantic tagging on ports — well, let's be honest and call them types — makes a great deal of sense, but it is unlikely to happen for built-in services as the state of metadata on things in the wild is usually pretty poor. But that's not to say that we're stuck. We're working on a component system for Taverna that will allow such semantic information to be placed on the ports, and that should then make it possible to do the type-assisted linking.
A summary of the current state of the component work is about to be put up at:
http://www.taverna.org.uk/developers/work-in-progress/components/(We're right in the middle of doing updates to that page; the next version will have improved info, when that goes up within a day or two.)
Also, I don't plan to share the workflows that there are pictures of on that page at the moment. They work, but are very specific to so many things — including this laptop I'm using — that you wouldn't find them useful. Sorry about that. There are a few components on myExperiment, but we're still exploring what we can do with them (and what exactly we have to do with them right now for the projects sponsoring the work).
