Overview
ISO/IEC 21000-22:2022 - Information technology - Multimedia framework (MPEG-21) - Part 22: User description defines formal data formats and model elements used to describe users, contexts, services and recommendations within the MPEG‑21 multimedia framework. The standard specifies four primary data formats: User Description (UD), Context Description (CD), Service Description (SD) and Recommendation Description (RD), and provides detailed syntax, semantics and examples for many reusable types. The document also notes technologies related to consecutive vibration.
Key technical topics and requirements
- Definition of four core data formats: UD, CD, SD, RD - canonical structures for exchanging user, context, service and recommendation data.
- Detailed type system and reusable building blocks, including:
- commonAttributes, ValueTypes, TimeType, ExtendedTimeType, LocationType
- ObjectType, ClassificationSchemeAliasType, InformationAccessUserGroup
- Profile and entity types: UserDescriptionType, UserProfileType, PersonProfileType, OrganizationProfileType, DeviceProfileType, GroupedProfileType
- Interaction and history types: UsageHistoryType, EventType, InteractionAtomType
- Media- and experience-related types: ArtefactType, ObservableType, MultimediaExperienceType, StateType, PreferenceType, TextPresentationPreferencesType
- Each type includes syntax, semantics and examples sections, enabling consistent implementation and interoperability.
- Normative references, terms & definitions, and structured examples support correct interpretation and integration.
- The scope explicitly includes specified technologies for consecutive vibration, indicating support for haptic or vibration-related descriptors in user experience models.
Practical applications and who should use this standard
- Multimedia system architects and developers implementing personalization, content adaptation, or user-aware delivery services.
- Service providers and content distributors who need interoperable user and context descriptions for adaptive streaming, recommendations and rights management.
- Device manufacturers and middleware vendors integrating device profiles, presentation preferences, or haptic/vibration capabilities.
- Accessibility specialists and UX designers modeling text presentation preferences, states and user preferences for assistive delivery.
- Researchers and standards authors extending or integrating MPEG‑21 metadata models in cross-platform multimedia ecosystems.
Related standards
- Part of the MPEG‑21 (ISO/IEC 21000) multimedia framework family. Implementers should review other MPEG‑21 parts for content identification, rights management, and delivery interoperability.
Keywords: ISO/IEC 21000-22, MPEG-21, User Description, Context Description, Service Description, Recommendation Description, user profile, device profile, content adaptation, personalization, multimedia framework, consecutive vibration.
