This is an archived WebSchemas proposal Medical and Health vocabulary for schema.org. See Proposals listing for more. Note: active schema.org development is now based at github


Note: the v0.95 revision of schema.org published on 2012-06-26 included this schema. Please use this page to track ideas for extension, improvement, problems etc.

This page describes a schema.org-based schema that webmasters and content publishers can use to mark up health and medical content on the web. Like all schema.org schemas, the health and medical schema is intended to make it easier for people to find the right web pages by exposing structured information contained in web pages to search engines, and may also enable other applications that make use of the structure.

The scope of this schema is broad, and is intended to cover both consumer- and professionally-targeted health and medical web content; as a result, any particular piece of content is likely to use only a subset of the schema.

Note as well that this schema is not intended to define or codify a new controlled medical vocabulary, but instead to complement existing vocabularies and onotologies. As a schema, its focus is on surfacing the existence of and relationships between entities described in content; the specific convention(s) used to name and/or code entities are outside of the scope of this schema. The schema does provide a way to annotate entities with codes that refer to existing controlled medical vocabularies (such as MeSH, SNOMED, ICD, RxNorm, UMLS, etc) when they are available. For example, see the sample markup for MedicalScholarlyArticle.


The full type hierarchy for the proposed extensions is available here. For more of an introduction to the proposed extensions, see this documentation page.
