Hi, I have an action: "Stephen to ask Luc's provenance team why they have chosen a separate provenance store." Luc's answer is below. Basically he says that it is a logically separate provenance store, but that it isn't necessarily physically separate. I'll not be able to make the telcon again this week - apologies. Cheers, Stephen. -------------------------- Stephen Davey, National e-Science Centre, Edinburgh, UK. -----Original Message----- From: Luc Moreau [mailto:L.Moreau@ecs.soton.ac.uk] Sent: 10 July 2006 12:38 To: Stephen Davey Subject: Re: Data Provenance Scenario Stephen, Sorry I forgot to reply to your message. In our deployment of the OTM, the provenance store is physically separated from the data. However, agreed with you, in other applicants you could see the provenance store as an extra port on your data storage, with data and process documentation all stored in a common physical storage.
