Awesome scufle2 rocks!!!
We are developing a workflow engine using apache storm, our plan is to use
the xml parser of Taverna so we can use Taverna files to load the workflows
on our server.
Our tesis is to use some Big Data techologies (use choose Apache Storm in
this case), to run scientific workflows, in this context we use Taverna
like SWfMS.
Thanks and probably we are going to send more emails on future :)
