You beat me to it :)

(cc:'ing Natasha Noy who led this work at at Google, and who might not be
able to post to this list directly but I can relay any bounced posts)

I am really happy to see this work launch and am happy to answer any
questions, here or offlist as folk prefer.

Schema.org's dataset vocab is based on the core pattern from the early DCAT
drafts a few years ago (and so shares its strengths and weaknesses). The
Google implementation is based on JSON-LD, RDFa and Microdata embedded in
the main per-dataset pages. While we focussed more on Schema.org there is
some understanding of DCAT too and our support for both will hopefully
evolve with the ecosystem (and updated W3C specs) over time. Other
questions of course loom, e.g. how this relates to markup for fact
checking, or for describing funders and projects, specialist domains (e.g.
bioschemas, ...), or other W3C efforts like Data Cube and CSVW....
