HL7 FHIR and Schema.org

Schema.org was developed by a number of major search engine companies such as Bing, Google and Yahoo! as a common vocabulary for marking up web pages. The combination of HTML and Microdata, RDFa 1.1 Lite or JSON-LD enables a well-known set of semantic tags to be added to existing human-readable web pages. Schema.org has been widely adopted by public web sites and multiple extensions have been created for domains such as automobiles, bibliographic resources, product classifications, healthcare and life sciences. The HL7 Fast Healthcare Interoperability Resources (FHIR) standard defines a standard set of "resources" that are used to exchange clinical and healthcare related information. FHIR is slated to become the de-facto interchange mechanism for healthcare and related information. We have developed a schema.org representation for the FHIR information models known as fhir.schema.org. The purpose of this representation was to promote discussion of the value of fhir.schema.org to annotate web based clinical information with their clinical model equivalent.
