Does the Taverna workbench itself > contain any information about the components that can be used? Do you mean what type of services can be added to a workflow? Yes the workbench "knows" as does the engine that executes the workflows. However, the information is not readily exposed in any interface that you can get at. > If so, is > it possible to extract this data so that I could look at it with a view to > representing it in some way that could be used by the myExperiment > ontology? The Scufl file, that a Taverna 1 workflow is saved as, is actually a serialization in XML of a ScuflModel. There is a brief description of ScuflModel at http://www.mygrid.org.uk/tools/developer-information/taverna-171-architecture/taverna-171-scufl-model/ which links into the Taverna 1.7.1 api at http://www.mygrid.org.uk/taverna/api/ It sounds as if you actually want to represent the Freefluo model that the Scufl workflow is converted into before execution. That isn't listed in the API that's online. Do you want me to put it up? > My understanding of how Taverna uses the scufl to produce a executable > workflow is minimal, so if there is a webpage/paper that explains this in > greater detail I would be interested in reading it. There are some details at http://www.mygrid.org.uk/tools/developer-information/taverna-171-architecture The most useful paper is from 2005 (the main information is still true) http://www3.interscience.wiley.com/cgi-bin/fulltext/112213653/PDFSTART > Regards > > David Newman Alan ------------------------------------------------------------------------------ _______________________________________________ taverna-hackers mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/taverna-hackers Developers Guide: http://www.mygrid.org.uk/usermanual1.7/dev_guide.html FAQ: http://www.mygrid.org.uk/wiki/Mygrid/TavernaFaq
