[DDI-SRG] DataKind

[Sanda Ionescu]

OK, Wendy.

To further clarify things:
- We meant to send the message, but, as I said before, were not sure if
we had done it. Ken was actually referring to this message, that
reflects the discussion within the Controlled Vocabularies Group. 
- Secondly, I was revising the message yesterday and saw no reason why
we should move Data Source to Study Unit. At this point, I think it's
fine to stay in Data Collection, so please ignore that part (do not file
as a bug)
- Am looking at DataKind in 2.1 right now. Forthcoming.

Sanda.

Subject: RE: DataKind

This came up during our TIC meeting. Ken mentioned it. I don't recall
seeing this email, but my brain has been turned off for a week so I may
just not recall it.

There is a reason for Data Source to be in Data Collection. Each Data
Collection activity may have a different Data Source and there needs to
be a clear connection between these. Why is it important to you that it
be in Study Unit?

Also, is it clear that the reason I'm asking about DataKind is that in
2.1 the DataProduct and the DataSource were a unique set (1..1) and in
3.0 there can be a n..1 (product to source) relationship
