Schema.org is a collaborative, community activity with a mission to create, maintain, and promote schemas/Taxonomy for Structured data on the Internet.

In addition to people from the founding companies (Google, Microsoft, Yahoo and Yandex), there is substantial participation by the larger Web community, through public mailing lists such as public-vocabs@w3.org and through GitHub and a Blog

Schema.org focuses on Microdata, most examples on the Schema.org site show examples in RDFa and JSON-LD too.

Schema.org is a Hierarchical Taxonomy based on a Thing which has four properties:

More specific types share properties with broader types. For example, a Place is a more specific type of Thing, and a LocalBusiness is a more specific type of Place. More specific items inherit the properties of their parent. (Actually, a LocalBusiness is a more specific type of Place and a more specific type of Organization, so it inherits properties from both parent types.)
