Schema.org is a initiative backed by big search engine to make your categorized content, including datasets, to show up on the first screen of search engine results. Here we use the contrib module schemaorg, and make use the Dataset class to expose metadata to the participating engines.

Schema.org offers a controlled vocabulary encoded in microdata, RDFa, or JSON-LD formats exposed structured and parsable information to content published out as HTML, and the marked up pages are recognized by search engines
