Thanks Marco. Fortunately i have a fair bit of TDi experience in the past. In fact the images that are in the Domino Directory were imported via TDI from an Oracle personnel DB.
However, I really do think that this aspect of Connections could be done better, and certainly could be documented more fully. Hence, I think that us admins should not have to dive straight into TDI for every requirement, and therefore asked if the wheel had already been invented elsewhere!
However, I appreciate your guidance. I'll give it a go.
