| ma:identifier |
{ (identifier:URI), (type:String)? } |
A tuple identifying a resource, which can be either an abstract
concept (e.g., Hamlet) or a specific object (e.g., an MPEG-4 encoding
of the English version of "Hamlet"), using a URI. The type can be used
to optionally define the category of the identifier. See use
case 4.4 of the Annotating Media Fragments Use Case document. An
example of such a tuple would be
{urn:uuid:36a87260-1102-11df-8a39-0800200c9a66, UUID}. |

{ (title:String), (type:String)? } |
A tuple that specifies the title or name given to the resource. The
type can be used to optionally define the category of the title. |

String |
The language used in the resource. A controlled vocabulary such as
[BCP 47] SHOULD be used. |

URL, or a DVB URI). |
| ma:contributor |
{ (identifier:(URI|String)), (role:String)? } |
A tuple identifying the agent, using either a URI or plain text. The
role can be used to optionally define the nature of the contribution
(e.g., actor, cameraman, director, singer, author, artist, or other
role types). The identifier SHOULD be defined as a URI. An example of
such a tuple is: {imdb:nm0000318, director}. |
| ma:creator |
{ (identifier:(URI|String)), (role:String)? } |
A tuple identifying the author of the resource, using either a URI or
plain text. The role can be used to optionally define the category of
author (e.g., playwright or author). The identifier SHOULD be defined
as a URI. The role is defined as plain text. An example of such a tuple
is: {dbpedia:Shakespeare, playwright}. |
| ma:createDate |
{ (date:Date), (type:String)? } |
A tuple defining the date and time that the resource was created. The
type can be used to optionally define the category of creation date
(e.g., release date, date recorded, or date edited). |
| ma:location |
{ (name:(URI|String))?, ((longitude:Float),
(latitude:Float), (altitude:Float), (coordinateSystem:String)?)?, } |
A tuple identifying an optional name and/or optional associated data
that describe where the resource has been created, developed, recorded,
or otherwise authored. The optional name can be defined using either a
URI or plain text; however, the name SHOULD be defined as a URI. The
optional location data MAY include longitude, latitude, and/or altitude
information, and it MAY also define a coordinate system that can be
used to interpret these measurements. |
| ma:description |
String |
Free-form text describing the content of the resource. |
| ma:keyword |
URI|String |
A concept, descriptive phrase or keyword that specifies the topic of
the resource, using either a URI or plain text. The identifier SHOULD
be defined as a URI. In addition, the concept, descriptive phrase, or
keyword contained in this element SHOULD be taken from an ontology or a
controlled vocabulary. |
| ma:genre |
URI|String |
The category of the content of the resource, using either a URI or
plain text. The identifier SHOULD be defined as a URI. In addition, the
genre contained in this element SHOULD be taken from an ontology or
controlled vocabulary, such as the EBU
vocabulary. |
| ma:rating |
{ (value:Float), (identifier:(URI|String))?,
((min:Float), (max:Float))? } |
A tuple defining the rating value, an optional rating person or
organization defined as either a URI or as plain text, and an optional
voting range. The identifier SHOULD be defined as a URI. The voting
range can optionally be used to define the minimum and maximum values
that the rating can have. |
| ma:relation |
{ (identifier:URI), (relation:String)? } |
A tuple that identifies a resource that the current resource is
related with (using either a URI or plain text), and optionally,
specifies the nature of the relationship. The identifier SHOULD be
defined as a URI. An example is a listing of content that has a
(possibly named) relationship to another content, such as the trailer
of a movie, or the summary of a media resource. |
| ma:collection |
URI|String |
The name of the collection (using either a URI or plain text) from
which the resource originates or to which it belongs. The collection
SHOULD be defined as a URI. |
| ma:copyright |
{ (copyright:String), (identifier:URI)? } |
A tuple containing the copyright statement associated with the
resource and optionally, the identifier of the copyright holder. Other
issues related to Digital Rights Management are out of scope for this
specification. |
| ma:policy |
{ (policy:URI|String), (type:String)? } |
A tuple that contains a description of the security policy that MUST
be applied to the media resource, or a reference to the security policy
(e.g., Creative Commons). This element is defined using either a URI or
plain text. The policy SHOULD be defined as a URI. In addition, the
type attribute can optionally be used to provide more information as to
the nature of the security policy (e.g., permissions, access control,
or ownership). |
| ma:publisher |
URI|string |
The publisher of a resource, defined as either a URI or plain text.
The publisher SHOULD be defined as a URI. |
| ma:targetAudience |
{ (identifier:URI), (classification:String) } |
A tuple identifying the issuer of the classification (e.g., a
parental guidance issuing agency, or a targeted geographical region)
and the value given in this classification. |
| ma:fragment |
{ (identifier:URI), (role:String)? } |
A tuple containing a fragment identifier and optionally, its role. A
fragment is a portion of the resource, as defined by the [MediaFragment] Working Group. |
| ma:namedFragment |
{ (identifier:URI), (label:String) } |
A tuple containing a named fragment identifier and its label. |
| ma:frameSize |
{ (width:Float), (height:Float), (unit:String)? } |
A tuple defining the frame size of the resource (e.g., width and
height of 720 and 480 units, respectively). The units can be optionally
specified; if the units are not specified, then the units MUST be
interpreted as pixels. |
| ma:compression |
String |
The compression type used. For container files (e.g., QuickTime,
AVI), the compression is not defined by the format, as a container file
can have several tracks that each use different encodings. In such a
case, several ma:compression instances SHOULD be used. Thus, querying
the ma:compression property of the track media fragments will return
different values for each track fragment. Note: it is possible to use
an extended MIME type as the value for
this property, see [RFC 4281]. |
| ma:duration |
Float |
The actual duration of the resource. The units are defined to be
seconds. |
| ma:format |
String |
TheMIME type of the resource (e.g.,
wrapper or bucket media types). |
| ma:samplingrate |
Float |
The audio sampling rate. The units are defined to be
samples/second. |
| ma:framerate |
Float |
The video frame rate. The units are defined to be frames/second. |
| ma:averageBitrate |
Float |
The average bit rate. The units are defined to be kbps. |
| ma:numTracks |
{ (number:Integer), (type:String)? } |
A tuple defining the number of tracks of a resource, optionally
followed by the type of track (e.g., video, audio, or subtitle). |
