The "DebianMed-Taverna-20110130" page has been changed by Hajo Krabbenhöft:

  Need to extend Taverna's data handling mechanisms to deal with this.  Need to improve some of the invocation mechanisms to better decide where to run the tools.
  
+ The plugin currently logs the job id's of all executed KnowARC grid jobs. This means we can freely re-use references to data because the user can clean up all his old grid jobs on demand. The user should be warned here, that this will invalidate any references and therefore should not be done while Taverna workflows are running.
+ 
+ In general, every invocation, independently of it's method, should be logged. Also, invocations should generally not clean-up any of their data, so that we can use references. When downloading a reference, we can after that delete the original file, because it's data is now stored inside Taverna.
+ 
+ This still leaves the problem on when to clean up past invocations. Should this happen after running the workflow? (Would make it impossible for the user to view unused output ports) When closing Taverna? Only when the user requests to do so? Timeout?
