[DDI-SRG] DataKind

[Sanda Ionescu]

Wendy, Mary, and others.

Looking more closely at the enumeration below, I think there is some
inconsistency, in that most concepts indicate how the data were
collected (by means of a survey, or an experiment, or observations,
etc.) while "aggregate data" does refer to the data product, and should
be a counterpart to "microdata" - possibly within a different
classification.
Maybe we should re-analyze this list within the Controlled Vocabularies
group and see what makes sense. But we definitely need a DataKind entry,
I think.

I may be thick, but I'm not sure exactly what you mean by "in  3.0 there
can be a n..1 (product to source) relationship". What is the "product"
you refer to? a data file? can you give an example?

Sanda.

I am adding the bug on missing DataKind and have a question. In DDI 2.0
there was a different StudyUnit for each logical product (e.g.
microdata, aggregate, etc from the 1990 Census). Does DataKind refer to
the data SOURCE or the data PRODUCT?
