Abstract

This document defines the Ontology for Media Resources 1.0. The term "Ontology" is used in its broadest possible definition: a core vocabulary. The intent of this vocabulary is to bridge the different descriptions of media resources, and provide a core set of descriptive properties. This document defines a core set of metadata properties for media resources, along with their mappings to elements from a set of existing metadata formats. Besides that, the document presents a Semantic Web compatible implementation of the abstract ontology using RDF/OWL. The document is mostly targeted towards media resources available on the Web, as opposed to media resources that are only accessible in local repositories.

1 Introduction

This document defines the Ontology for Media Resources 1.0. In this document, the term "ontology" is used in its broadest possible definition: a core vocabulary. The Ontology for Media Resources 1.0 is both a core vocabulary (a set of properties describing media resources) and its mapping to a set of metadata formats currently describing media resources published on the Web. Mappings to formats for media resources non available on the Web have not been taken into account in this version of the Ontology. The purpose of the mappings is to provide an interoperable set of metadata, thereby enabling different applications to share and reuse these metadata. The set of properties of the Ontology for Media Resources 1.0 was selected with respect to the most commonly adopted set of elements from metadata formats currently in use to describe media resources.

Ideally, the mappings defined in this document would preserve the semantics of a metadata item across metadata formats. In reality, however, this cannot be easily achieved: there is often a difference in the extension of what is covered by the elements (or terms) from different formats. This means that a mapping between the Ontology's property and the elements from two different formats that have such a difference will not allow a semantic-preserving mapping. For example, the property dc:creator from the Dublin Core and the property exif:Artist defined in the Exchangeable Image File Format, or EXIF are both mapped to the property creator, in the Ontology. The document therefore also specifies types of mappings: "exact", "more specific", "more generic" and "related". Nevertheless, mapping back and forth between properties from different schemata, using only the Ontology defined in this specification as a reference, will induce a certain loss in semantics. Mechanisms for correcting for this loss are beyond the scope of this document.

The Ontology defines mappings between its set of properties and the elements from metadata formats commonly used to describe media resources. The namespace for the Ontology is http://www.w3.org/ns/ma-ont#, which is identified with the "ma" prefix in this document. Although some of the properties can appear to be redundant with Dublin Core, there are several differences that distinguish them:

The Media Ontology (i.e. the core set of properties and mappings defined in this specification) provides the basic information needed by targeted applications (see Use Cases and Requirements for Ontology and API for Media Ressource 1.0) for supporting interoperability among the various kinds of metadata formats related to media resources that are available on the Web. The Ontology is accompanied by an API (see API for Media Resources 1.0) that provides a uniform access to all of its elements. Furthermore a Semantic Web compatible implementation of the Ontology is available which is presented in Section 7 of this document. This implementation uses the Semantic Web ontology languages RDF/OWL and its derivation from the core vocabulary is presented in detail with it.

The properties defined in this document are used to describe media resources that are available on the web. Media resources can denote both the abstract concept of a media resource (e.g., the movie "Notting Hill") as well as a specific instance (e.g., a certain file with an MPEG-4 encoding of the English version of "Notting Hill" with French subtitles). For the sake of simplicity, we do not make distinctions between these different levels of abstraction that exist in some formats (e.g., [FRBR])

1.1 Formats in scope

This section is normative; however, examples contained in this section are informative.

The following table lists the formats that were selected as in-scope of a potential mapping from the Media Ontology, along with the identifiers which are used as prefixes to identify them in this specification.

We distinguish multimedia metadata formats that focus on the description of multimedia resources from multimedia container formats. In the case of the latter, only few technical properties are relevant for the Ontology for Media Resources, because of they widespread usage. Very specific properties are out of the scope of this specification

2 Conformance Requirements

This section is normative.

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.

3 Terminology

This section is normative.

[Definition: Ontology]

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.

[Definition: Media Resource]

A media resource is any physical or logical resource that can be identified using a Uniform Resource Identifier (URI), as defined by [RFC 3986]), which has or is related to one or more media content types. Note that [RFC 3986] points out that a resource may be retrievable or not. Hence, this term encompasses the abstract notion of a movie (e.g., Notting Hill) as well as the binary encoding of this movie (e.g., the MPEG-4 encoding of Notting Hill on a DVD), or any intermediate levels of abstraction (e.g., the director's cut or the plain version of the Notting Hill movie). Although some ontologies (FRBR, BBC) define different concepts for different levels of abstraction, other ontologies do not. Therefore, in order to foster interoperability, the ontology defined in this specification does not provide such a classification of media resources.

[Definition: Property]

A property is an element from an existing metadata format for describing media resources, or an element from the core vocabulary as defined in this specification. For example, the Dublin Core dc:creator element and the Media Ontology creator element are both properties. A property links a Media Resource with a literal value or another resource. In the above example, the dc:creator property links a given resource with the value of its creator property. In this example, Dublin Core does this by defining the dc:creator property as follows: "Examples of a creator include a person, an organization, or a service".

Properties can have structured or unstructured values. The set of properties defined in the Media Ontology core vocabulary is listed in section 5 Property definitions.

[Definition: Mapping]

For the purposes of this document, a mapping is defined as a function that transforms information represented in one schema using one format to information in a different schema that uses a different format. In this document, a set of mappings are defined between a subset of the "in scope" Vocabularies and the properties of the core vocabulary of the Media Ontology that is defined in this document. These mappings are presented in section 5.2 Property mapping table.

[Definition: Property value types]

Property value types are the data types of the values for a property. For example, the property dc:creator can have either string or URI as data types. Property value types are defined in section 4 Property value type definitions. They are dependent on XML Schema data types [XML Schema 2].

4 Property value type definitions

This section is normative.

4.1 URI

"A Uniform Resource Identifier", or URI, is defined in [RFC 3986]. In this specification, the term URI is used, since it is well known. However, the use of this term is extended in this specification to also include "Internationalized Resource Identifiers" (IRIs), as defined in [RFC 3987]. An IRI is a URI that MAY contain non-escaped characters other than ASCII characters. The data type is anyURI. Hence, in this specification, the term "URI" MUST be interpreted to also include IRI.

4.4 Decimal

A Decimal value SHOULD be represented using the XML Schema decimal data type, but MAY be represented using the XML Schema double data type if decimal is not available.

5 Property definitions

This section is normative; however, examples contained within this section are informative.

5.1 Core property definitions

5.1.1 Description of the approach followed for the property definitions

This list of core properties has been defined by creating an initial set of mappings from the list of vocabularies in scope. The core list is a selection of the properties that were supported by the majority of the vocabularies in scope [findtop10].

The ranking of the core properties by expected importance, as determined by the use cases defined in Use Cases and Requirements for Ontology and API for Media Resource 1.0, has been used as an additional criteria for narrowing down the set of core properties for this specification. The resulting set of properties is nearly identical to that chosen by the [jpsearch] initiative.

The following information is available for each property:

Several properties in this specification are defined as complex types, consisting of a tuple of attributes. This is used to support qualifiers and optional attributes. Hence, a special syntax has been defined to accommodate this requirement, and is explained below.

All properties names are intentionally in singular form and MUST contain only a single value. However, multiple instances of a property MAY be used. In addition, each property MAY have an associated language attribute, which can be used to enable several instances of that property to be defined in different languages.

The following syntax is used for the type descriptions:

  • ( ) (parentheses) are used to indicate a attribute/value pair

  • | (vertical bar) is used to indicate a choice between different values

  • { } (curly brackets) are used to define a complex type, i.e., a tuple of attribute/value pairs

  • ? (question mark) is used to indicate an optional element

contributor { (attName="contributor", attValue="URI" | "String"), (attName="role", attValue="URI" | "String")? } is interpreted as a complex type that has two elements. The first identifies the contributor of a media resource by using a URI or a string. The second specifies an optional role, which is defined by a string. Elements are comma separated, and the collection of elements that makes up the complex type is enclosed in curly brackets.

5.1.2 Descriptive properties (Core Set)

NameType definitionDescription
Identification
identifier(attName="identifier", attValue="URI")A URI identifying a media 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"). When only legacy identifiers are available, a URI must be minted, for example using the tag: scheme [RFC 4151].
title{ (attName="title", attValue="String"), (attName="type", attValue="URI" | "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.
language(attName="language", attValue="URI" | "String")The language used in the resource. We recommend to use a controlled vocabulary such as [BCP 47]. An BCP 47 language identifier can also identify sign languages e.g. using ISO 639-3 subtags like bfi (British sign language).
locator(attName="locator", attValue="URI")The logical address at which the resource can be accessed (e.g. a URL, or a DVB URI).
Creation
contributor{ (attName="contributor", attValue="URI" | "String"), (attName="role", attValue="URI" | "String")? }A tuple identifying the agent, using either a URI (recommended best practice) 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). An example of such a tuple is: {imdb:nm0000318, director}.
creator{ (attName="creator", attValue="URI" | "String"), (attName="role", attValue="URI" | "String")? }A tuple identifying the author of the resource, using either a URI (recommended best practice) or plain text. The role can be used to optionally define the category of author (e.g., playwright or author). The role is defined as plain text. An example of such a tuple is: {dbpedia:Shakespeare, playwright}.
date{ (attName="date", attValue="Date"), (attName="type", attValue="URI" | "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).
location{ (attName="name", attValue="URI" | "String")?, (attName="longitude", attValue="Decimal")?, (attName="latitude", attValue="Decimal")?, (attName="altitude", attValue="Decimal")?, (attName="coordinateSystem", attValue="URI" | "String")? } A tuple identifying a name or a set of geographic coordinates, in a given system, that describe where the resource has been created, developed, recorded, or otherwise authored. The name can be defined using either a URI (recommended best practice) or plain text. The geographic coordinates include longitude, latitude and an optional altitude information, in a given geo-coordinate system (such as the World Geodetic System) that MAY also be specified. At least a name or (longitude, latitude) must be provided. A registry of coordinate reference systems such as EPSG Geodetic Parameter Dataset can be used to identify coordinate systems by URIs.
Content description
description(attName="description", attValue="String")Free-form text describing the content of the resource.
keyword(attName="keyword", attValue="URI" | "String")A concept, descriptive phrase or keyword that specifies the topic of the resource, using either a URI (recommended best practice) or plain text. In addition, the concept, descriptive phrase, or keyword contained in this element SHOULD be taken from an ontology or a controlled vocabulary.
genre(attName="genre", attValue="URI" | "String")The category of the content of the resource, using either a URI (recommended best practice) or plain text. In addition, the genre contained in this element SHOULD be taken from an ontology or controlled vocabulary, such as the EBU vocabulary.
rating { (attName="value", attValue="Decimal"), (attName="ratingSystem", attValue="URI" | "String")?, {(attName="min", attValue="Decimal"), (attName="max", attValue="Decimal")}? } The rating value (e.g., customer rating, review, audience appreciation), specified by a tuple defining the rating value, an optional rating person or organization defined as either a URI (recommended best practice) or as plain text, and an optional voting range. The voting range can optionally be used to define the minimum and maximum values that the rating can have.
Relational
relation{ (attName="target", attValue="URI" | "String"), (attName="type", attValue="URI" | "String")? } A tuple that identifies a resource that the current resource is related with (using either a URI -recommended best practice- or plain text), and optionally, specifies the nature of the relationship. 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.
collection(attName="collection", attValue="URI" | "String")The name of the collection (using either a URI or plain text) from which the resource originates or to which it belongs. We recommend to use a URI, as a best practice.
Rights
copyright{ (attName="copyright", attValue="String"), (attName="holder", attValue="URI" | "String")? }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.
policy{ (attName="statement", attValue="URI" | "String"), (attName="type", attValue="URI" | "String")? } A tuple containing a policy statement either human readable as a string or machine resolvable as a URI, and the type of the policy to provide more information as to the nature of the policy. See examples.
Distribution
publisher(attName="publisher", attValue="URI" | "String")The publisher of a resource, defined as either a URI or plain text. We recommend, as a best practice, to define the publisher as a URI.
targetAudience { (attName="audience", attValue="URI" | "String"), (attName="classificationSystem", attValue="URI" | "String")? }A tuple identifying the audience being addressed (demographic class, parental guidance group, or geographical region) and an optional classification system (e.g., a parental guidance issuing agency). .
Fragment
fragment{ (attName="identifier", attValue="URI"), (attName="role", attValue="URI" | "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.
namedFragment{ (attName="identifier", attValue="URI"), (attName="label", attValue="String") }A tuple containing a named fragment identifier and its label.
Technical Properties
frameSize{ (attName="width", attValue="Decimal"), (attName="height", attValue="Decimal"), (attValue="unit", attValue="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.
compression(attName="compression", attValue="URI" | "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 compression instances should be used. Thus, querying the compression property of the track media fragments will return different values for each track fragment. Either or both of two values may be supplied: a URI, and a free-form string which can be used for user display or when the naming convention is lost or unknown. The URI consists of a absolute-URI (RFC 3986 [RFC 3986], section 4.3) and fragment (RFC 3986 [RFC 3986], section 3.5), that is, e.g. in the form absolute-URI#name. The absolute-URI identifies the naming convention used for the second parameter, which is a string name from that convention. A URL is preferred for the URI, and if it is used, it (a) might contain a date in the form mmyyyy, indicating that the owner of the domain in the URL agreed to its use as a label around that date and (b) should be de-referencable, yielding an informative resource about the naming convention. Note that this use of URIs with fragments also closely matches RDF (see RDF concepts). Note that for some container files, the format parameter can also carry an extended MIME type to document this; see [RFC 4281] for one such instance. See examples.
duration(attName="duration", attValue="Decimal")The actual duration of the resource. The units are defined to be seconds.
format(attName="format", attValue="URI" | "String")The MIME type of the resource (e.g., wrapper or bucket media types), ideally including as much information as possible about the resource such as media type parameters, for example, using the "codecs" parameter [RFC 4281].
samplingRate(attName="samplingRate", attValue="Decimal")The audio sampling rate. The units are defined to be samples/second.
frameRate(attName="frameRate", attValue="Decimal")The video frame rate. The units are defined to be frames/second.
averageBitRate(attName="averageBitRate", attValue="Decimal")The average bit rate. The units are defined to be kbps.
numTracks{ (attName="number", attValue="Integer"), (attName="type", attValue="String")? }A tuple defining the number of tracks of a resource, optionally followed by the type of track (e.g., video, audio, or subtitle).

A number of these properties use qualifiers to define subtypes and roles: identifier, title, contributor, creator, date, relation, collection, policy, fragment and numTracks. In addition, the location, rating, copyright, and frameSize properties use optional elements to define the unit of measure of their values, the ranges that the values of these elements can have, or other supplementary information. All subtype and role qualifiers for these properties are optional. The set of possible values for subtypes is not normative. However, whenever possible, values defined in an existing controlled vocabulary or classification scheme SHOULD be used.

5.2 Property mapping table

5.2.1 Rationale regarding the mapping table

The mappings between the Media Ontology and a subset of the "in-scope" vocabularies of this specification specify both the semantic and some elements of the syntactic correspondences between the Media Ontology properties and the elements of a given vocabulary. The vocabularies selected were those that were deemed to be the most popular and useful regarding the proposed Use Cases (see Use Cases and Requirements for Ontology and API for Media Ressource 1.0).

5.2.1.1 Semantic Level Mappings

The presented mappings are uni-directional mappings, because the semantics of the elements being mapped from the same Media Ontology property may be very different across formats. For example, copyright is mapped to both xmpDM:copyright and dc:rights (as part of the XMP standard [XMP]); the same property is mapped to exif:Copyright (see [EXIF]). Unfortunately, no semantic relationship can be inferred between the elements defined in the XMP and EXIF standards. The mappings that have been taken into account have different semantics that have one of the following four characteristics:

  • Exact match: the semantics of the two properties are equivalent in all possible contexts. For example, the semantics of the property title exactly matches the semantics of the property vra:title.

  • More specific: the property of the vocabulary taken into account has associated semantics that contain a superset of the semantics expressed by the property defined in this specification. For example in DIG35, ipr_names@description and ipr_person@description are both more specific than the property publisher to which they are mapped.

  • More generic: the inverse of the above, meaning that the property of the vocabulary taken into account has associated semantics that is broader than the property defined in this specification. For example, the DIG35 location is more general than the location property.

  • Related: the two properties are related in a way that is relevant for some use cases, but this relation has no defined and/or commonly applied semantics. For example, in Media RSS, media:credit is related to creator.

This list of relations between vocabularies (or informal mappings) and the "Core Media Properties list" is published as a table. Feedback from people or companies actually using the different vocabularies in communities that are currently using the different vocabularies is very welcome; if such feedback is received, it will be incorporated into an updated of this specification.

5.2.1.3 Mapping expression

The mapping expression corresponds to the concrete implementation or representation of the mappings defined in the previous paragraph, both at a semantic level and at syntactic one.

SKOS (acronym for the Simple Knowledge Organization System) is a Recommendation of the W3C Semantic Web activity which defines a vocabulary for representing Knowledge Organization Systems, such as vocabularies, and relationships amongst them. In SKOS the mapping properties that we take into account in the mapping table are expressed as: skos:exactMatch, skos:narrowMatch, skos:broadMatch and skos:relatedMatch.

A future version of this specification may include additional information about the properties. For example, some restrictions might be added to a set of mappings (e.g., if they are symmetric) to enhance more efficient mappings. If such changes are implemented, every effort will be made to produce a new and revised specification that is backwards-compatible with the current version of this specification.

5.2.2 Multimedia metadata formats mapping tables

The following mappings are established from the Media Ontology's properties to various multimedia metadata formats. This list of formats is not closed, nor does it pretend to be exhaustive. A future version of this specification may include additional mappings if a need or use case is established for these new mappings.

For each format there is a mapping table with the following columns.

5.2.2.1 CableLabs 1.1

For the Cablelabs format the mapping table has the following extra columns.

Type (MediaType): Defines the type of asset that this field refers to in the Cablelabs 1.1 ADI and Content Specs. The type defines whether the asset is a movie, a still or other structure in the whole Video package.

  • Spec: In CableLabs Cablelabs 1.1 ADI and Content Specs there are two specifications (ADI and CONTENT) which apply to the management of the content and the content metadata itself. The AMS refers to the former, the MOD or SVOD refers to the latter - defining the type of service used.

  • Metadata Name: Defines the actual field value of the named field.

    6 Usage Examples

    This section is informative

    6.2 Subtitles and the Ontology for Media Resources

    Concerning external subtitles, using relation is the recommended approach. The identifier attribute contains the URL of the subtitle file, and the relation type qualifies it as a subtitle relation. The value should be a URI, but could also be a string. It is recommended to use a controlled vocabulary for the type of the relation.

    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) [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 [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.

    6.4 Captions and signing

    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:

    • an additional track of the media file,
    • embeded in the video track,
    • as a separate file.

    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> ;
    

    6.5 Language for media resources

    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 main spoken language is british english (<span><tt>en-GB</tt></span>),
    • at some point, a sentence in french is spoken (<span><tt>fr</tt></span>),
    • the file contains a subtitle track in spanish (<span><tt>es</tt></span>),
    • the video track contains embedded signing in british sign language (<span><tt>bfi</tt></span>).

    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 audio track associated with british english,
    • a temporal fragment of the audio track associated with french,
    • the subtitle track associated with spanish,
    • the spatial fragment of the video track associated with sign language.

    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" ] .
    
    

    7 Namespace and RDF-representation of the Ontology for Media Resources 1.0

    This section is normative

    This section presents an implementation of the Ontology for Media Resources as a Semantic Web ontology. At first a namespace for the Ontology is defined (Section 7.1). Secondly, an implementation guideline is given which details how the core vocabulary defined in this specification relates to the RDF vocabulary (Section 7.2). Finally Section 7.3 presents an RDF vocabulary which implements the abstract ontology using RDF and OWL. The ontology is a valid OWL2 DL ontology and it can be directly used to describe media resource on the Web in a Semantic Web and Linked Data compatible way. The ontology has been built using standard ontology engineering methodologies in a small expert group inside the MAWG working group.

    7.1 Namespace of core property definitions

    The namespace of the Ontology for Media Resources 1.0 is defined by this URI: http://www.w3.org/ns/ma-ont#. Applications that are compliant with this specification MUST use this namespace URI.

    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 ma prefix name is associated with the namespace URI http://www.w3.org/ns/ma-ont# in this document.

    7.2 Correspondence between the informal ontology and the RDF representation

    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].
