Overview
ISO/IEC 15938-5:2003/Amd 3:2008 is an international standard amendment focused on improving the geographic descriptor within the multimedia content description interface framework. Issued by ISO and IEC, it enhances Part 5 of the MPEG-7 standard, which defines multimedia description schemes. This amendment introduces expanded capabilities for describing geographic positions associated with multimedia content, including the definition of multiple points, accuracy values, and classification of geographic data types.
By refining geographic descriptors, this standard supports more precise and versatile metadata for multimedia assets, facilitating better indexing, searching, and interoperability across diverse information technology and multimedia systems.
Key Topics
Enhanced Geographic Position Definition
The amendment enables the representation of a geographic position with one or more points, improving detail and flexibility in location description.Accuracy Attribute
Introduces an accuracy parameter indicating the precision of geographic coordinates in meters, strengthening the reliability of spatial metadata.Geographic Position Types
Supports categorization of geographic data into three types:- Point: A single coordinate representing a precise location.
- Area: Multiple points forming a closed shape, defining a geographic region.
- Route: An ordered sequence of points representing a path or route.
Schema Updates
Defines updated XML schema structures for the PlaceType complex type, including elements such as Name, Role, GeographicPosition, AstronomicalBody, Region, AdministrativeUnit, PostalAddress, and InternalCoordinates.Practical Example
Demonstrates real-world application with a detailed example describing a shooting location at a university in Madrid, Spain, illustrating how to use the improved geographic descriptor in practice.
Applications
The amendment’s enhancements to geographic descriptors have practical value across multiple domains, including:
Multimedia Content Management
Enables precise tagging and geotagging of images, videos, and audio files, improving content retrieval based on location.Digital Libraries and Archives
Facilitates richer metadata for cultural heritage and educational resources, where geographic context is crucial.Geospatial Information Systems (GIS)
Assists in integrating multimedia content within GIS platforms by providing accurate geographic metadata.Broadcasting and Film Production
Supports location-based metadata for video shoots, documentaries, and live events, optimizing production management.Mobile and Location-Based Services
Enhances location-aware applications by standardizing how geographic data is embedded in multimedia descriptions.
Related Standards
ISO/IEC 15938 (MPEG-7)
The umbrella standard for multimedia content description interfaces, where Part 5 defines multimedia description schemes further elaborated by this amendment.ISO/IEC JTC 1/SC 29
The joint technical committee and subcommittee involved in coding of audio, picture, multimedia, and hypermedia information, responsible for this amendment.Geospatial Metadata Standards
Complementary standards like ISO 19115 for geographic information metadata offer integration possibilities alongside MPEG-7 geographic descriptors.
By adhering to ISO/IEC 15938-5:2003/Amd 3:2008, organizations can ensure consistent and highly accurate multimedia geographic metadata, enhancing interoperability and discoverability in international multimedia and information technology environments.

Foreword
ISO (the International Organization for Standardization) and IEC (the International Electrotechnical
Commission) form the specialized system for worldwide standardization. National bodies that are members of
ISO or IEC participate in the development of International Standards through technical committees
established by the respective organization to deal with particular fields of technical activity. ISO and IEC
technical committees collaborate in fields of mutual interest. Other international organizations, governmental
and non-governmental, in liaison with ISO and IEC, also take part in the work. In the field of information
technology, ISO and IEC have established a joint technical committee, ISO/IEC JTC 1.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of the joint technical committee is to prepare International Standards. Draft International
Standards adopted by the joint technical committee are circulated to national bodies for voting. Publication as
an International Standard requires approval by at least 75 % of the national bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO and IEC shall not be held responsible for identifying any or all such patent rights.
Amendment 3 to ISO/IEC 15938-5:2003 was prepared by Joint Technical Committee ISO/IEC JTC 1,
Information technology, Subcommittee SC 29, Coding of audio, picture, multimedia and hypermedia
information.
This Amendment provides the ability to define a geographical position with one or more Points, the ability to
provide an accuracy value related to the Points and the ability to define the type of GeographicPosition Point
details.
