This all looks really interesting! A quick pointer to some modest
tweaks we are expecting to include in the next (v.3.1) release of
schema.org that touch on datasets:

Release candidate draft: http://webschemas.org/docs/releases.html#v3.1

Specifically around issue #1083 http://webschemas.org/docs/releases.html#g1083

See page for hyperlinked version but excerpting here:

"Issue #1083: Improvements primarily around Dataset, generalized
spatialproperty of Dataset to become spatialCoverage of any
CreativeWork; similarly generalized temporal as temporalCoverage.
Indicated that spatialCoverage is a subproperty of contentLocation.
Broadened sponsor to apply to creative works such as datasets, and
added a more specific subproperty to indicate funder.Amended
definition of MediaObject to match its use as a supertype
ofDataDownload. Amended fileFormat to allow URL as a way of indicating
niche or unregistered file formats (common for scientific datasets).
Added a draftvariablesMeasured property to the pending extension."

This is currently under review, with a goal of releasing in the next
week or so: https://lists.w3.org/Archives/Public/public-schemaorg/2016Jul/0015.html
