But I don't believe Taverna is able to record for example the actual software code used in the experiment, i.e. archiving the dynamics aspects of a workflow run. The provenance should only be able to record what the Taverna enactor can observe. And the code used behind the services will not be observable and preserved in provenance. This should be what our WF4Ever project should handle:) > > The users can browse the intermediate values and go back to inspect > older workflow runs. >> They want all these data to be presented in a friendly way, and always >> the flexibility to execute complex queries. > At the moment, there is no UI to query the provenance database nor it is > easy to query it directly without in-depth understanding of how it is > organised (and it is very complex). > > We are planning some improvements in that respect in Taverna 2.3, such > as exporting provenance data as OPM and Janus support, which will make > it easier for people to manipulate their provenance data and export if > from the Taverna's provenance database for inspection outside of Taverna. This must happen, for a user point of view! And I am very looking forward to it. It's also very important to allow your group pals to view the data and provenance generated by you. A Web-based explorer interface could be a preference to many people. > > What we would like to know is what scale are the workflows your users > will likely run?

It is not being able to run the workflows that is the most important for them, but being to effectively manage their results, share them, and explore and query them, with a good UI support :) >> >> Nothing new nor particularly specific to chemistry, apart from some >> details. > OK, if you need some help about Taverna in chemistry - the best person > to contact is Peter Li<[email protected]>.
