Google Dataset Search by the Numbers

Understand

Scientists, governments, and companies increasingly publish datasets on the Web.

• Google's Dataset Search extracts dataset metadata -- expressed using schema.org and similar vocabularies -- from Web pages in order to make datasets discoverable.
• Since we started the work on Dataset Search in 2016, the number of datasets described in schema.org has grown from about 500K to almost 30M.
• Thus, this corpus has become a valuable snapshot of data on the Web.
