My understanding is that the package operation would be used to e.g. prepare a questionnaire and all that is needed for displaying and testing (structureMaps, valuesets etc). 

Another type of package would for measures. 

Another could be for test data

Another would be for semantic validation (getting a logical model, its dependencies, valuesets, invariants, extensions, conceptmaps).

How are these types of packages defined? I would expect the following:

a) getting all dependencies may not be a good choice as some dependencies may be irrelevant for some purposes.

b) relying only on the resource type may not be sufficient as different resource types may serve completely different purposes (e.g. structuredefs).

Would we have a type for these? 

How can we produce all these packages from an ig?

This issue is being raised as a consequence of trying to do something simple as packaging a questionnaire for debugging a structuremap - turns out to be minute work, complicated, tedious and prone to issues. If the package operation is to support that, we can push it as part of the expected tools.
