Hi, I was thinking earlier today, about the possibility of using transcoding for exchanging one workflow language for that of another. I was thinking of an example by Manchester [1], that looks at CSS to extract information from Web pages for the visually impaired. An example given in the link is that Web Pages are heterogenous to one another and make it difficult for visually impaired people to find menu's and main content. Researchers on that project used CSS to find the relevant parts and strip them out (e.g. <menu>Text<menu>), putting them into a 'proper' order that could be read out by a screen reader.
My naive thoughts were that a derivative of this could be used to convert from one workflow language (e.g. BPEL or Kepler) to another (e.g. Scufl or T2Flow). If it is possible to identify common elements in a workflow language (as with the bits in the css file) such as the services used, and the links between those elements, the workflow could be converted into a 'standard language'. I use standard here in the idealistic principle that comes with youth, and not experience. If the workflow tools implemented a means of reading in this standard, then you would have some primitive means of interoperability between the various tools. As a result, I would then be able to run Kepler workflows in Taverna, and visa versa. Could I propose 'Paul' to be the name of this standard :) or maybe something more practical like : WFDL (instead of [2]). Anyway...... Paul. [1] - Simon Harper, Sean Bechhofer, Darren Lunn.
