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:

top level media type, and
media subtype

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:

Lvl	Code	Display	Definition	internalId	status	synonymCode
1	application	ApplicationMediaType	Application specific media type.	21083	active
2	application/dicom	DICOM	Digital Imaging and Communications in Medicine (DICOM) MIME type defined in RFC3240 \[http://ietf.org/rfc/rfc3240.txt\].	21460	active
2	application/msword	MSWORD	This format is very prone to compatibility problems. If sharing of edit-able text is required, text/plain, text/html or text/rtf should be used instead.	14834	active
2	application/pdf	PDF	The Portable Document Format is recommended for written text that is completely laid out and read-only. PDF is a platform independent, widely deployed, and open specification with freely available creation and rendering tools.	14833	active
1	audio	AudioMediaType	Audio media type.	21084	active
2	audio/basic	Basic Audio	This is a format for single channel audio, encoded using 8bit ISDN mu-law \[PCM\] at a sample rate of 8000 Hz. This format is standardized by: CCITT, Fascicle III.4 -Recommendation G.711. Pulse Code Modulation (PCM) of Voice Frequencies. Geneva, 1972.	14836	active
2	audio/k32adpcm	K32ADPCM Audio	ADPCM allows compressing audio data. It is defined in the Internet specification RFC 2421 \[ftp://ftp.isi.edu/in-notes/rfc2421.txt\]. Its implementation base is unclear.	14838	active
2	audio/mpeg	MPEG audio layer 3	MPEG-1 Audio layer-3 is an audio compression algorithm and file format defined in ISO 11172-3 and ISO 13818-3. MP3 has an adjustable sampling frequency for highly compressed telephone to CD quality audio.	14837	active
1	image	ImageMediaType	Image media type.	21085	active
2	image/g3fax	G3Fax Image	This is recommended only for fax applications.	14843	active
2	image/gif	GIF Image	GIF is a popular format that is universally well supported. However GIF is patent encumbered and should therefore be used with caution.	14841	active
2	image/jpeg	JPEG Image	This format is required for high compression of high color photographs. It is a "lossy" compression, but the difference to lossless compression is almost unnoticeable to the human vision.	14842	active
2	image/png	PNG Image	Portable Network Graphics (PNG) \[http://www.cdrom.com/pub/png\] is a widely supported lossless image compression standard with open source code available.	14840	active
2	image/tiff	TIFF Image	Although TIFF (Tag Image File Format) is an international standard it has many interoperability problems in practice. Too many different versions that are not handled by all software alike.	14844	active
1	model	ModelMediaType	Model media type.	21086	active
2	model/vrml	VRML Model	This is an openly standardized format for 3D models that can be useful for virtual reality applications such as anatomy or biochemical research (visualization of the steric structure of macromolecules)	14849	active
1	multipart	MultipartMediaType	Multipart Media Type	21087	active
2	multipart/x-hl7-cda-level-one	CDA Level 1 Multipart	The HL7 clinical document Architecture, Level 1 MIME package.	14851	active	multipart/x-hl7-cda-level1
2	multipart/x-hl7-cda-level1	CDA Level 1 Multipart	The HL7 clinical document Architecture, Level 1 MIME package.	14851	retired	multipart/x-hl7-cda-level-one
1	text	TextMediaType	For any text	21088	active
2	text/html	HTML Text	For marked-up text according to the Hypertext Mark-up Language. HTML markup is sufficient for typographically marking-up most written-text documents. HTML is platform independent and widely deployed.	14828	active
2	text/plain	Plain Text	Description:For any plain text. This is the default and is used for a character string (ST) data type.	14826	active
2	text/rtf	RTF Text	The Rich Text Format is widely used to share word-processor documents. However, RTF does have compatibility problems, as it is quite dependent on the word processor. May be useful if word processor edit-able text should be shared.	14831	active
2	text/sgml	SGML Text	For structured character based data. There is a risk that general SGML/XML is too powerful to allow a sharing of general SGML/XML documents between different applications.	14829	active
2	text/x-hl7-ft	HL7 Text	For compatibility, this represents the HL7 v2.x FT data type. Its use is recommended only for backward compatibility with HL7 v2.x systems.	14827	active
2	text/x-hl7-text+xml	HL7 Structured Narrative	Description: The content described by the CDA Narrative Block (not just used by CDA).	22607	active
2	text/xml	XML Text	For structured character based data. There is a risk that general SGML/XML is too powerful to allow a sharing of general SGML/XML documents between different applications.	14830	active
1	video	VideoMediaType	Video media type.	21089	active
2	video/mp4	MP4 Video	Video format by the Motion Picture Experts Group under ISO/IEC 14496	24125	active
2	video/mpeg	MPEG Video	MPEG is an international standard, widely deployed, highly efficient for high color video; open source code exists; highly interoperable.	14846	active
2	video/quicktime	QuickTime Video	Proprietary video format from Apple, Inc.	24127	active
2	video/webm	WebM Video	A royalty-free audiovisual media file format.	24128	active
2	video/x-avi	X-AVI Video	The AVI file format is just a wrapper for many different codecs; it is a source of many interoperability problems.	14847	active
2	video/x-ms-wmv	Windows Media Video	Proprietary video format from Microsoft, Inc.	24126	active
