Expansion based on codesystem Media Type v3.0.0 (CodeSystem)

This value set contains at least 34 concepts.

1  applicationhttp://terminology.hl7.org/CodeSystem/v3-mediaTypeApplicationMediaType

Application specific media type.

2    application/dicomhttp://terminology.hl7.org/CodeSystem/v3-mediaTypeDICOM

Digital Imaging and Communications in Medicine (DICOM) MIME type defined in RFC3240 [http://ietf.org/rfc/rfc3240.txt].

2    application/mswordhttp://terminology.hl7.org/CodeSystem/v3-mediaTypeMSWORD

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.

2    application/pdfhttp://terminology.hl7.org/CodeSystem/v3-mediaTypePDF

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.

1  audiohttp://terminology.hl7.org/CodeSystem/v3-mediaTypeAudioMediaType

Audio media type.

2    audio/basichttp://terminology.hl7.org/CodeSystem/v3-mediaTypeBasic 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.

2    audio/k32adpcmhttp://terminology.hl7.org/CodeSystem/v3-mediaTypeK32ADPCM 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.

2    audio/mpeghttp://terminology.hl7.org/CodeSystem/v3-mediaTypeMPEG 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.

1  imagehttp://terminology.hl7.org/CodeSystem/v3-mediaTypeImageMediaType

Image media type.

2    image/g3faxhttp://terminology.hl7.org/CodeSystem/v3-mediaTypeG3Fax Image

This is recommended only for fax applications.

2    image/gifhttp://terminology.hl7.org/CodeSystem/v3-mediaTypeGIF Image

GIF is a popular format that is universally well supported. However GIF is patent encumbered and should therefore be used with caution.

2    image/jpeghttp://terminology.hl7.org/CodeSystem/v3-mediaTypeJPEG 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.

2    image/pnghttp://terminology.hl7.org/CodeSystem/v3-mediaTypePNG Image

Portable Network Graphics (PNG) [http://www.cdrom.com/pub/png] is a widely supported lossless image compression standard with open source code available.

2    image/tiffhttp://terminology.hl7.org/CodeSystem/v3-mediaTypeTIFF 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.

1  modelhttp://terminology.hl7.org/CodeSystem/v3-mediaTypeModelMediaType

Model media type.

2    model/vrmlhttp://terminology.hl7.org/CodeSystem/v3-mediaTypeVRML 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)

1  multiparthttp://terminology.hl7.org/CodeSystem/v3-mediaTypeMultipartMediaType

Multipart Media Type

2    multipart/x-hl7-cda-level-onehttp://terminology.hl7.org/CodeSystem/v3-mediaTypeCDA Level 1 Multipart

The HL7 clinical document Architecture, Level 1 MIME package.

2    multipart/x-hl7-cda-level1http://terminology.hl7.org/CodeSystem/v3-mediaTypeCDA Level 1 Multipartinactive

The HL7 clinical document Architecture, Level 1 MIME package.

1  texthttp://terminology.hl7.org/CodeSystem/v3-mediaTypeTextMediaType

For any text

2    text/htmlhttp://terminology.hl7.org/CodeSystem/v3-mediaTypeHTML 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.

2    text/plainhttp://terminology.hl7.org/CodeSystem/v3-mediaTypePlain Text

**Description:**For any plain text. This is the default and is used for a character string (ST) data type.

2    text/rtfhttp://terminology.hl7.org/CodeSystem/v3-mediaTypeRTF 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.

2    text/sgmlhttp://terminology.hl7.org/CodeSystem/v3-mediaTypeSGML 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.

2    text/x-hl7-fthttp://terminology.hl7.org/CodeSystem/v3-mediaTypeHL7 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.

2    text/x-hl7-text+xmlhttp://terminology.hl7.org/CodeSystem/v3-mediaTypeHL7 Structured Narrative

Description: The content described by the CDA Narrative Block (not just used by CDA).

2    text/xmlhttp://terminology.hl7.org/CodeSystem/v3-mediaTypeXML 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.

1  videohttp://terminology.hl7.org/CodeSystem/v3-mediaTypeVideoMediaType

Video media type.

2    video/mp4http://terminology.hl7.org/CodeSystem/v3-mediaTypeMP4 Video

Video format by the Motion Picture Experts Group under ISO/IEC 14496

2    video/mpeghttp://terminology.hl7.org/CodeSystem/v3-mediaTypeMPEG Video

MPEG is an international standard, widely deployed, highly efficient for high color video; open source code exists; highly interoperable.

2    video/quicktimehttp://terminology.hl7.org/CodeSystem/v3-mediaTypeQuickTime Video

Proprietary video format from Apple, Inc.

2    video/webmhttp://terminology.hl7.org/CodeSystem/v3-mediaTypeWebM Video

A royalty-free audiovisual media file format.

2    video/x-avihttp://terminology.hl7.org/CodeSystem/v3-mediaTypeX-AVI Video

The AVI file format is just a wrapper for many different codecs; it is a source of many interoperability problems.

2    video/x-ms-wmvhttp://terminology.hl7.org/CodeSystem/v3-mediaTypeWindows Media Video

Proprietary video format from Microsoft, Inc.

Explanation of the columns that may appear on this page:

Level A few code lists that FHIR defines are hierarchical - each code is assigned a level. In this scheme, some codes are under other codes, and imply that the code they are under also applies
System The source of the definition of the code (when the value set draws in codes defined elsewhere)
Code The code (used as the code in the resource instance)
Display The display (used in the display element of a Coding). If there is no display, implementers should not simply display the code, but map the concept into their application
Definition An explanation of the meaning of the concept
Comments Additional notes about how to use the code
