But first, I just want to check on the status of the latest draft draft at http://www.w3.org/TR/vocab-dcat, in light of the Resolutions recorded at the WG 2012-10-25 meeting, below. Can I assume these resolutions should (and someday will) be reflected in the latest draft, and just haven't been added yet?

Yes, all these will be reflected in the specification very soon. We are currently dedicating some time and effort to DCAT and this hopefully will reflect soon in the specification.
The working draft that we are continuously updating can be found at: https://dvcs.w3.org/hg/gld/raw-file/default/dcat/index.html 

> Also wondering about dcat:granularity, which I understand was split into dcat:spatial and dcat:temporal. However, those concepts both pertain to coverage, whereas granularity means the geographic size of things. For instance, I might have a dataset with records that have a granularity of "national" but spatially cover a region described as "South America." Would appreciate suggestions on how to address this.

use dc:spatial for coverage (this will have "South America" as a value) and dcat:granularity to indicate the granularity (this will have "national" as a value). However, please be aware that dcat:granularity and its possible splitting into dcat:spatial and dcat:temporal are still under discussion (see https://www.w3.org/2011/gld/track/issues/10 )

Hope that helps and please keep an eye on the specification… we will show some serious progress soon!

Best regards,
Fadi
