In 2.1 beta 2 the information about the run is captured in a database and it is this data which is used to produce the "intermediate results" information. For 2.1, Paolo Missier, Ian Dunlop and Stuart Owen have been working on improving the provenance capture. This includes OPM support and an API to allow out-of-Taverna access to the provenance data. > I have the following > questions : > > 1.

The relevant packages are under net.sf.taverna.t2.provenance. net.sf.taverna.t2.provenance.lineageservice.Provenance takes events and passes them to net.sf.taverna.t2.provenance.lineageservice.EventProcessor You would probably want to implement your own EventProcessor. Paolo and Ian can give more details. > 3. Is there any documentation which points out how to create a new plugin > for tavern. There will be archetypes available, certainly for activity plugins, for 2.1. > Thanks, > Girish Subramanian Alan ------------------------------------------------------------------------------ Come build with us!
