Overview
ISO/IEC 21000-19:2010/Amd 1:2018 is an amendment to Part 19 of the MPEG‑21 Multimedia Framework: the Media Value Chain Ontology (MVCO). This amendment extends MVCO to support precise description of time‑segments and multi‑track audio within composite audio IP entities. The standard formalizes the model as a normative OWL ontology (MVCO and an audio extension AUMVCO), supplies normative OWL/XML‑RDF in the annexes, and provides informative guidance and an API for ontology use.
Key topics and technical elements
- Ontology formalization: MVCO is expressed as an OWL ontology; the audio extension ontology URI is http://purl.oclc.org/NET/aumvco.owl. Normative OWL content is provided in Annexes B and C.
- New audio concepts: introduces classes and properties to represent:
- Segment (a slice of an IP Entity that may contain another IP Entity)
- Interval, TimeLine, Track and their relationships
- Temporal properties: interval, start, end, duration, onTimeLine
- Track relations: hasTrack, onTrack
- Containment and part‑of relationships: hasSegment, contains
- Actions and rights: extends MVCO with actions such as Reuse (reuse of an IP Entity in a composite item) to enable rights and permissions modeling for sampled or reused audio.
- Interoperability bases: the timeline model references OWL Time concepts and a Timeline Ontology; the amendment aligns MVCO with existing multimedia metadata needs.
- Documentation: Clause structure, narrative model (Clause 6), formal ontology description (Clause 7), audio extension (Clause 8), and normative OWL in annexes.
Practical applications
- Rights management and licensing: locate reused samples, DJ mix segments, or per‑track content to determine ownership, permissions and royalties.
- Metadata enrichment for multi‑track formats: annotate multi‑track interactive music (e.g., MPEG‑A: Interactive Music Application Format) with per‑track IP provenance and segment timing.
- Content tracking and reporting: enable automated systems to trace contributions and value‑chain relationships across time and tracks for reporting and payouts.
- Media asset management and discovery: improve search, reuse detection, and versioning by specifying segments and track associations in metadata.
Who should use this standard
- Metadata architects, rights management system designers, music publishers, streaming platforms, DRM solution developers, and archives handling composite or multi‑track audio where accurate provenance, reuse tracking, and license enforcement are required.
Related standards
- ISO/IEC 21000 (MPEG‑21) series - MVCO is Part 19
- ISO/IEC 23000‑12 (MPEG‑A: Interactive Music Application Format) - referenced as a multi‑track use case
- W3C OWL Time and timeline ontologies - temporal modeling foundations
This amendment helps organizations model media value chains with precise temporal and track‑level metadata, enabling more transparent and automated rights management for contemporary audio production and distribution.
