This document contains normative, non-normative, and informative sections. The parts of this document that define the Ontology, as well as the syntactic and semantic level mappings between elements from existing formats and the core properties defined in this document, are normative, and are marked as such. For normative sections only, the keywords "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "RECOMMENDED", "MAY", and "OPTIONAL" are to be interpreted as described in RFC2119 [ RFC 2119 ]. To facilitate the differentiation between the normative use of these terms as defined in RFC2119 and a non-normative use of these terms, the normative use of these terms MUST occur in all capital letters. All other sections, including examples, are not normative.
A "strictly conforming" application is one that satisfies all "MUST" and "SHALL" provisions in this document. In contrast, a "conditionally conforming" application is one that satisfies all "MUST" provisions in this document, but not all "SHALL" provisions. It should be noted that an application that does not specify all "MUST" provisions in this document is not conforming".
Note: In this specification the use of "Media Ontology" and "Ontology for Media Resources 1.0 " is equivalent.
A formal definition of an ontology is as follows. "An ontology is a formal, explicit specification of a shared, often machine-readable, vocabulary. Its meaning, in the form of entities and relationships between them, intends to describe some knowledge in a given domain. Formal refers to the fact that the ontology should be representable in a formal grammar. Explicit means that the entities and relationships used, and the constraints on their use, are precisely and unambiguously defined in a declarative language suitable for knowledge representation. Shared means that all users of an ontology will represent a concept using the same or equivalent set of entities and relationships. Domain refers to the content of the universe of discourse being represented by the ontology" [ KEUO ]. In this specification, the broadest possible definition of an ontology is used: a shared vocabulary. The vocabulary in question is the list of core properties (relationships) defined here (prefixed ma in this document); its machine-readable format is specified in the following section . The vocabulary used is RDF [ RDF ]. However, implementations are not limited to using RDF. Implementations MAY use different formats and still be considered to be conformant with this specification, as long as they comply to the definition of the properties listed in the following section 5 .

Embedding of subtitles is not a use case that has been considered, however it is possible. The mechanism used to specify timed metadata is to specify fragments identified by Media Fragment URIs [ MediaFragment ] and then describe annotations of these fragments.
To summarize, there are three options for dealing with subtitles:
Link
to
external
subtitle
file
using
fragment,
with
type
subtitle
and
a
Timed
Text
Markup
Language
(TTML)
[
IPTC
TTML
]
or
WebSRT
[
WebSRT
]
file
as
target.
Subtitles
can
be
embedded
in
a
media
file,
in
which
case
they
can
be
described
as
a
track
media
fragment
using
fragment
and
Media
Fragment
URIs
[
TVA
MediaFragment
].
Subtitles could be embedded by using title with a type qualifier for subtitle. A list of time media fragments is defined and each fragment is annotated using title.
Although the last option is a way of embedding subtitles it is not recommended. Instead, a dedicated format such as TTML or WebSRT should be used for the subtitles and referenced.
EBUCore
Time
based
annotations
are
a
possible
and
the
following
two
cases
are
covered
by
the
specification:
Core property definitions section defines a gerenal property fragment with a role attribute to specify the relation between the resource and its fragment, like captioning or signing. In the RDF representation , this is achieved by defining subproperties of the <span><tt>ma:hasFragment</tt></span> property.
Captions and signing of a media resource can be provided in different forms, the most typical being:
To account for this diversity, the RDF ontology does not link <span><tt>ma:hasTrack</tt></span> with <span><tt>ma:hasCaptioning</tt></span> or <span><tt>ma:hasSigning</tt></span> . The last two can link a media resource to any fragment, e.g. a spatial fragment of the video track where the signing is located, or even an external file considered as a fragment of the resource. If the fragment is also a track, nothing prevents to link it with both properties <span><tt>ma:hasCaptioning</tt></span> and <span><tt>ma:hasTrack</tt></span> .
For example, the following RDF describes a video with embeded signing, subtitles as an external file, and a track containing audio-description (caption for accessibility):
<video.ogv> a ma:MediaResource ;
ma:hasSigning <video.ogv#xywh=percent:70,70,90,90>;
ma:hasSubtitling <./video.srt> ;
ma:hasAudioDescription <video.ogv?track=subtitle> ;
ma:hasTrack <video.ogv?track=subtitle> ;
SMTPD
The
core
set
of
properties
proposed
in
section
5
only
defines
a
single
property
for
specifying
the
language
of
a
media
resource.
However,
a
media
resource
may
have
several
languages.
For
example,
a
video
file
can
have
the
following
languages
applying
to
it:
The four language codes could be directly applied to the video file, using the language core property <span><tt>ma:hasLanguage</tt></span> in the RDF representation), but this would lose a part of the information.
If one wants to keep the complete information, the recommended option is to assign each language to the appropriate fragment of the video, using [MediaFragment] to identify them, and the core property fragment <span><tt>ma:hasFragment</tt></span> and its subproperties in the RDF representation to link them to the video file itself. In the example above, we would have:
The corresponding RDF would be:
<video.ogv> a ma:MediaResource ;
ma:hasTrack <video.ogv#track=audio>,
<video.ogv#track=subtitle>;
ma:hasSubtitling <video.ogv#track=subtitle> ;
ma:hasSigning <video.ogv#xywh=percent:70,70,90,90> .
<video.ogv#track=audio> a ma:AudioTrack ;
ma:hasLanguage [ rdfs:label "en-GB" ] ;
ma:hasFragment <video.ogv#track=audio&t=10,20> .
<video.ogv#track=audio&t=10,20> a ma:MediaFragment ;
ma:hasLanguage [ rdfs:label "fr" ] .
<video.ogv#track=subtitle> a ma:DataTrack ;
ma:hasLanguage [ rdfs:label "es" ] .
<video.ogv#xywh=percent:70,70,90,90> a ma:MediaFragment ;
ma:hasLanguage [ rdfs:label "bfi" ] .
The

Note:
As specifications that use this namespace URI progress through the standardization process, they MUST use the same namespace URI. This namespace URI is expected to remain the same throughout the evolution of this ontology, even in the case new properties are added to it, so long as it remains backwards compatible. If however a new version were produced that was not backwards compatible, the WG reserves the right to change the namespace URI.

The following table gives the correspondence between the core properties as described in the Descriptive properties (Core Set)section and the RDF vocabulary given below.
Unless stated otherwise, atomic values are represented by literals while complex values are represented by resources. It follows that, in the general case, properties with complex values are represented by object properties, while properties with simple values are represented by datatype properties. Attributes in complex values are represented by properties of the resource representing the complex value; depending on their semantics, they are represented by datatype or object properties.
The RDF ontology also introduces a number of classes corresponding to the domains and ranges of the corresponding property.

(1) The identifier of a media resource is represented in RDF by the URI of the node representing that media resource. If a resource is identified by several URI, owl:sameAs should be used.
(2) Different values of this attribute should be represented by subproperties of the original property; the RDF ontology provides such subproperties for the most common cases.
(3) If the value is a string, the RDF property should point to a blank node with that string as its rdfs:label; if the value is a URI, the RDF property should point to a resource with that URI.
(4) The pattern is the same as (3), but the value to consider is that of an attribute of the complex value.
(5) This property has no direct correspondence; the properties corresponding to the attributes of the complex value apply directly to the media resource.
(6) According to Section 4.4 , several datatypes are allowed here. However, if compliance with a specific OWL 2 Profile is required, additional constraints on the allowed datatypes may apply [ OWL2 Profiles ].
