Re: Index of Types -> Domains

Speaking not to where the domain usage counts on schema.org come from (Dan
Brickley might be able to address that), but this specifically:

> "... examples of domains implementing a particular Type or format in
their pages"

While the last structured data extraction was generated from a crawl now
more than a year old, the Web Data Commons (http://www.webdatacommons.org/)
does make statistics available on "RDFa, Microdata, Embedded JSON-LD, and
Microformats" found in each crawl, as well as the full corpus.  You can
find the most recent data here:

Web Data Commons Extraction Report - October 2016 Corpus
http://www.webdatacommons.org/structureddata/2016-10/stats/stats.html

If you have the desire to do so, you can also access and analyze Common
Crawl data yourself (data sets are generated monthly); learn more here:
