Is HL7 a license?
At the same time that FHIR was being initially developed, HL7 made a very brave move. Previous versions of HL7 Standards (v2, v3 and CDA) were all licensed by HL7. To use them required paying a license fee to HL7, which is how it funded the development efforts. However, the decision was made to make FHIR and the other standards open source. Anyone could use it without paying a fee, though the ownership remained with HL7 to ensure that it continued to be developed in an open way. While this has no doubt contributed to the wide spread adoption of FHIR, it has come at a (literal) cost to HL7, as a large part of its income had come from license fees, and alternative revenue sources were needed.

Within the United States there are many other SDOs that are involved in the development of EHR-related standards, most notably ASTM [8] and the Object Management Group Health Domain Task Force (OMG HDTF) [9]. ASTM has been most active in the area of EHR content standards (e.g. the Continuity of Care Record standard) whilst the HDTF have made a significant contribution to the development of open service specifications such as COAS (Clinical Observation Access Service), PIDS (Person Identification Service), TQS/LQS (Terminology/Lexicon Query Service), and RAD (Resource Access Service). DICOM is the peak international SDO for image storage and communication in health.
What is a profile in EHR?
Profiles help to manage the master list of functions. A “Profile” is a selected set of functions that are applicable for a particular purpose , user , care setting, domain, etc. It is not anticipated that the full set of functions will apply to any single EHR-S implementation. Instead, the functions are profiled for particular care settings and for particular uses. Care Setting Profiles relate priorities (Essential/Now, Essential/Future, Optional, Not Applicable) to specific functions. Ultimately, self-generated Profiles will express the capabilities of a real system (e.g., a vendor’s product or a set of applications) or the needs of a stakeholder
