Schema.org

Schema.org is an initiative sponsored by Google, Microsoft, Yahoo and Yandex that promotes a very pragmatic approach to the semantic web/linked data.

At the time of writing over 10 million sites use Schema.org to markup content, and many applications of the involved companies (e.g., GMail, Google Calendar) exploit Schema.org metadata to provide added value features (e.g., automatically interpreting reservation details to add events to your calendar).

Ontology

The Schema.org ontology has, at the time of writing, relatively little support for software-related entities, most notably:

• Code
• SoftwareApplication
• SoftwareSourceCode
