Thanks Stian. Wasn't sure if the original question was a MyGrid subject (it being a Taverna-agnostic question).
Anyhow... the workflow description language is one part of the equation, which would be very useful to solve. Scripting or hand-editing isn't quite so important here - what's important is the interoperability between different workflow engines. Taverna gets halfway there by allowing workflows to be constructed, saved, and reloaded later, but the resulting XML is still Taverna-specific. I'm imagining something generic enough that I could do 'Save as...' from Taverna, and later load the same file into another toolwithout any problems, e.g. Pipeline Pilot (heaven forbid!), or vice versa. The other part of the equation is an engine other than Taverna to run these generic workflows in (should the developer/user not want/be able to have Taverna/Java installed on their machine, or they want to embed the execution inside a non-Java bit of software, e.g. a Perl script). Do other workflow execution engines exist that have APIs for other non-Java languages?
