Re: [SPAM] OpenWFE - other workflow formalisms and engines

Thanks for this info, Chimezie.

I completely agree with your avoidance of re-inventing this  
particular wheel.

I think the point you make at the end of this email is a very  
important one.  I assume the answer is it's a little bit of both.

That is why I posted my question - really just a slight elaboration  
on Joanne's request.

So - in regards to the issue Chimezie stated below - workflow  
vocabularies vs. workflow formalisms/engines capable of using them -  
how does Taverna weigh in.  I assume given those who've been working  
on Taverna development this issue of use of formal semantic  
frameworks for workflow entities & relations are in fact a part of  
what Taverna uses to drive decisions and assemble run-time parameters  
& data sets.

If this issue was discussed today in the ACPP TCon, the minutes may  
suffice to answer this question.

Cheers,
Bill
