Internet Assigned Numbers Authority (IANA) Mime Media Types. Identifies the type of the encapsulated data and identifies a method to interpret or render the data. The IANA defined domain of media types is established by the Internet standard RFC 2045 [http://www.ietf.org/rfc/rfc2045.txt] and 2046 [http://www.ietf.org/rfc/rfc2046.txt]. RFC 2046 defines the media type to consist of two parts:
However, this HL7 datatypes specification treats the entire media type as one atomic code symbol in the form defined by IANA, i.e., top level type followed by a slash “/” followed by media subtype. Currently defined media types are registered in a database [http://www.iana.org/assignments/media-types/index.html] maintained by IANA. Currently several hundred different MIME media types are defined, with the list growing rapidly. In general, all those types defined by the IANA MAY be used.

Properties
This code system defines the following properties for its concepts
Code | URI | Type | Description |
Specializes | Coding | The child code is a more narrow version of the concept represented by the parent code. I.e. Every child concept is also a valid parent concept. Used to allow determination of subsumption. Must be transitive, irreflexive, antisymmetric. | |
Generalizes | Coding | Inverse of Specializes. Only included as a derived relationship. | |
internalId | http://terminology.hl7.org/CodeSystem/utg-concept-properties#v3-internal-id | code | The internal identifier for the concept in the HL7 Access database repository. |
status | http://hl7.org/fhir/concept-properties#status | code | Designation of a concept's state. Normally is not populated unless the state is retired. |
synonymCode | http://hl7.org/fhir/concept-properties#synonym | code | An additional concept code that was also attributed to a concept |
Concepts
This case-sensitive code system http://terminology.hl7.org/CodeSystem/v3-mediaType
provides a fragment that includes following codes in a Is-A heirarchy:
