| Threading: | ↑ [provenance-challenge] New provenance queries from Washington workshop from sm AT ecs.soton.ac.uk • This Message |
Bertram This is a coincidence -- we also discussed this in the myGrid planning meeting today as we are concerned that we do not have the resources to set aside for the challenge and produce the Taverna 1.5 release, esp. as Jun, Duncan and Antoon are writing up their PhDs right now and Sky isn't up to speed as he has just started. So we are seriously considering withdrawing from the second challenge. Carole > Hi Simon and all: > > Re. the 2nd Prov.
