HL7 and HL7 FHIR. Health Level Seven (HL7) began as a US-centric standards organization, but has since grown to be adopted and used globally. HL7 defines several broad but related families of standard, including the HL7 Version 2 (V2) standard which specifies how clinical and healthcare information can be exchanged using a message idiom, the Clinical Document Architecture (CDA), which specifies how information is represented and exchanged using a structured document paradigm and FHIR, which standardizes the representation of healthcare information using the Resource Oriented Architecture (ROA) style [[Principled Design of the Modern Web Architecture (Fielding and Taylor, May, 2002)]][[Restful Web Services. Richardson and Ruby. 2007]]. The primary focus of these three standards are (to date) primary clinical care. The HL7 FHIR standard, in particular, is emerging as a de-facto model for the representation and exchange of clinical data.
