Content Metadata

Content metadata standards are published by SCTE, INCITS, CTA, ISO, DS, BS, SS, DIN, and ONORM. Content metadata describes values such as page titles, video descriptions, and topic of discussion. SCTE 236 describes grammar needed to represent content metadata. INCITS/ISO/IEC 11179 covers naming principles of metadata registries. CTA 861.3 covers HDR static metadata extensions and is available for free PDF download. ISO documents cover XML metadata interchange, metadata mapping procedures, basic attributes of metadata, extended classification metadata, statistical data and metadata exchange,meta object facility, and the Dublin core metadata element set. DS standards cover metadata dictionary structure and the minimum set of metadata for cinematographic works. BS standards cover the Dublin core metadata element set DCMI properties and classes and statistical data and metadata exchange. SS-ISO 15836 also covers the Dublin core metadata set properties and classes. DIN EN 15907 and ONORM EN 15744 both cover film identification.

SCTE 236 2017

Content Metadata

This standard describes the grammar needed to represent information pertinent to the distribution, presentation and consumption of multimedia content. In a normal use case, the metadata originates from a provider and is distributed to operators.

INCITS/ISO/IEC 11179-5:2015 (R2021)

Information technology - Metadata registries (MDR) - Part 5: Naming principles

Provides instruction for naming of the following items, as defined in ISO/IEC 11179-3: concept, data element concept, conceptual domain, data element, and value domain. Describes naming in a metadata registries (MDR); includes principles and rules by which naming conventions can be developed; and provides examples of naming conventions.

CTA 861.3-A-2016

HDR Static Metadata Extensions

This standard specifies static High Dynamic Range (HDR) metadata extensions using an additional InfoFrame and EDID CTA data block, replacing previously reserved codes in Table 5 and Table 46 of CTA-861-F [1]. Recommendations regarding the usage of static HDR metadata are also provided.

ISO/IEC 19503:2005

Information technology - XML Metadata Interchange (XMI)

The main purpose of ISO/IEC 19503:2005 (XMI) is to enable easy interchange of metadata between application development lifecycle tools (such as modeling tools based on the Unified Modeling Language (UML), ISO/IEC 19501, and metadata repositories/frameworks based on the Meta Object Facility (MOF), ISO/IEC 19502) in distributed heterogeneous environments. ISO/IEC 19503:2005 integrates three key industry standards:

  • XML, eXtensible Markup Language, a W3C standard;
  • UML, Unified Modeling Language, an OMG modeling specification which is now ISO/IEC 19501;
  • MOF, Meta Object Facility (ISO/IEC 19502).

ISO/IEC 19503:2005 provides specifications for

  • a set of XML Schema Definitions (XSD) production rules for transforming MOF-based metamodels into XML Schemas;
  • a set of XML Document production rules for encoding and decoding MOF-based metadata;
  • design principles for XMI-based Schemas and XML documents;
  • a set of production rules for importing XML DTDs to a MOF-based metamodel.

ISO/IEC 19503:2005 enhances metadata management and metadata interoperability in distributed object environments in general and in distributed development environments in particular. While it addresses stream-based metadata interoperability in the object analysis and design domain, ISO/IEC 19503:2005 (in part because it is MOF based) is equally applicable to metadata in many other domains.

DS/EN 62261-1:2007

Television METADATA - Part 1: Metadata dictionary structure

Covers the use of metadata for all types of essence (video, audio, and data in their various forms). Applications of individual dictionary entries will vary but, when used, metadata shall conform to the definitions and formats in this metadata dictionary structure standard and the associated metadata dictionary recommended practice (EN 62261-3)

ISO/IEC TR 19583-1:2019

Information technology - Concepts and usage of metadata - Part 1: Metadata concepts

This document describes the basic concept of metadata, and its relationship to both data and metamodels.

ISO/IEC TR 20943-5:2013

Information technology - Procedures for achieving metadata registry content consistency - Part 5: Metadata mapping procedure

The purpose of ISO/IEC TR 20943-5:2013 is to describe a procedure for establishing metadata crosswalks based on the ISO/IEC 11179 series, subsequently improving mapping quality between metadata.

Therefore, ISO/IEC TR 20943-5:2013 describes a metadata mapping procedure (MMP), which can maximize the interoperability among ISO/IEC 11179-based registries through achieving metadata registry content consistency.

ISO/IEC TS 11179-30:2019

Information technology - Metadata registries (MDR) - Part 30: Basic attributes of metadata

This document specifies basic attributes which are required to describe data elements and associated metadata, and which might be used in situations where a complete ISO/IEC 11179-3 metadata registry is not appropriate (e.g. in the specification of other International Standards).

ISO 17369:2013

Statistical data and metadata exchange (SDMX)

ISO 17369:2013 provides an integrated approach to facilitating Statistical Data and Metadata Exchange (SDMX), enabling interoperable implementations within and between systems concerned with the exchange, reporting and dissemination of statistical data and related metadata.

ISO 17369:2013 is applicable to any organization that has a need to manage the reporting, exchange and dissemination of its statistical data and related metadata. The information model at the core of ISO 17369:2013 has been developed to support statistics as collected and used by governmental and supra-national statistical organizations, and this model is also applicable to other organizational contexts involving statistical data and related metadata.

ISO/IEC 19502:2005

Information technology - Meta Object Facility (MOF)

ISO/IEC 19502:2005 defines a metamodel (defined using Meta Object Facility, MOF), a set of interfaces [defined using Open Distributed Processing (ODP) Interface Definition Language (IDL) (ITU-T Recommendation X.920 (1997) | ISO/IEC 14750:1999)], that can be used to define and manipulate a set of interoperable metamodels and their corresponding models. ISO/IEC 19502:2005 also defines the mapping from MOF to ODP IDL. These interoperable metamodels include the Unified Modeling Language (UML) metamodel (ISO/IEC 19501:2005), the MOF meta-metamodel, as well as future standard technologies that will be specified using metamodels. The MOF provides the infrastructure for implementing design and reuse repositories, application development tool frameworks, etc. The MOF specifies precise mapping rules that enable the CORBA interfaces for metamodels to be generated automatically, thus encouraging consistency in manipulating metadata in all phases of the distributed application development cycle. Mappings from MOF to W3C XML and XSD are specified in ISO/IEC 19503. Mappings from MOF to Java (TM) are in the JMI (Java Metadata Interchange) specification defined by the Java Community Process.

ISO/IEC 19502:2005 specifies

  • an abstract language for specifying, constructing, and managing technology neutral metamodels (a metamodel is in effect an abstract language for some kind of metadata);
  • a framework for implementing repositories and integration frameworks (e.g., tool integration frameworks) that hold metadata (e.g., models) described by the metamodels and which uses standard technology mappings to transform MOF metamodels into metadata APIs.

ISO/IEC 19502:2005 also provides

  • a formal definition of the MOF meta-metamodel, i.e. the abstract language for specifying MOF metamodels;
  • a mapping from arbitrary MOF metamodels to CORBA IDL that produces IDL interfaces for managing any kind of metadata;
  • a set of 'reflective' CORBA IDL interfaces for managing metadata independent of the metamodel;
  • a set of CORBA IDL interfaces for representing and managing MOF metamodels;

an XMI format for MOF metamodel interchange (OMG XMI specification).

Information and documentation. The Dublin Core metadata element set DCMI Properties and classes (British Standard)

This document establishes a vocabulary for cross-domain resource description, known as the Dublin Core metadata terms (hereafter DCMI Metadata Terms). It includes all of the properties and classes in the main namespace of DCMI Metadata Terms[1] (hereafter "the /terms/ namespace"), as published in the DCMI Recommendation document "DCMI Metadata Terms" of 2012 (DCMI-TERMS and Annex A). As explained in Annex B, these properties and classes can be identified by URIs for use in linked data.

NOTE The 15 terms of the original Dublin Core Metadata Element Set, as defined in the namespace https://purl.org/dc/elements/1.1/ (hereafter "the /elements/1.1/ namespace"), are also documented in the DCMI Recommendation "DCMI Metadata Terms" and in ISO 15836-1.

This document does not contain the following supporting terms from "DCMI Metadata Terms" specification:

a) terms from the /elements/1.1/ namespace (included in ISO 15836-1);

b) vocabulary encoding schemes;

c) syntax encoding schemes;

d) DCMI Type vocabulary;

e) terms related to the DCMI Abstract Model.

Both ISO 15836-1 and this document include the 15 so-called core terms, but in ISO 15836-1 they are from the /elements/1.1/ namespace, and in this document from the /terms/ namespace. In the latter, the terms have narrower semantics due to formal domain and range specifications.

This document does not limit what might be a resource.

This document does not provide specific implementation guidelines. The properties and classes are typically used in the context of an application profile, which constrains or specifies their use in accordance with local or community-based requirements and policies.

Film identification - Minimum set of metadata for cinematographic works

This European Standard contains a comprehensive set of metadata elements for representing information about cinematographic works, their variants and manifestations. Detailed information on available media items, viewing requirements, and access conditions is not covered by this standard. However, elementary information concerning the availability of media items can be expressed. *This European Standard also provides some extension points for adding more detailed data types without violating conformance. The guiding principle here is that no information from existing filmographic records should be lost when these are expressed according to this standard. Finally, an XML schema is provided as an aid to data interchange and as a tool for verifying the syntactic conformance of implementations.

SS-EN 15907:2010

Film identification - Enhancing interoperability of metadata - Element sets and structures (Swedish Standard)

This European Standard specifies a set of metadata for the description of cinematographic works, as well as a terminology for use by parties wishing to exchange such descriptive metadata. It also defines some basic entities and relationships useful for defining data models as well as for structuring hierarchically ordered and serialised representations of metadata about cinematographic works including their variants, manifestations, and items. Specific vocabularies for values of elements and attributes are mandated only in selected cases, and only if these vocabularies are actively maintained by a standardisation body.
