Projects in Metadata Information ManagementEBU members, manufacturers, academics, etc. (150+)

The main projects:

MIM-MM (Modelling and metadata specifications, semantic web)

Class conceptual data model (CCDM), EBUCore,

MIM-SCAIE

o automatic extraction tools, test material and reference data -> AVDP

MIM-AM

o Acquisition technical and descriptive metadata (camera, camcorders)

MIM-Metadata Developer Network Task

o Exchange of best practices, examples, tools, softwares, etc.

MIM-DFXP

o EBU-TTML (timed text)

MIM-FIMS

o Service oriented architecture, user group of EBU/AMWA FIMS

EBUCore: Dublin Core for media

Based on the Dublin Core but better defined with more structured audio and video attributes.

EBUCore adopted by FP7 EUScreen (AV archive portal):

- 15 EBU members participate as content providers;

- EBUCore is mapped to the Europeana data model (EDM).

EBUCore & PrestoPrime: Positive evaluation

But the scope of EBU is not restricted to archives:

- Exists also as an RDF OWL ontology: semantic web and linked data ready!

- Mapping to the W3C Media Annotation ontology based on EBU CCM

- Adopted by EBU-AMWA FIMS for SOA service definition, by AES (AES60)

- Many resources: mapping tools, JSON representation, etc.

- Used in media production: MediaCorp (Singapore), Bloomberg (USA), etc.

egta Metadata – File exchange for advertising

egta: Association of Television and Radio Sales Houses

o Work supported by EBU members: FranceTV, RAI, WDR

Scope: A schema for file exchange of advertising spots

Result: The egtaMETA schema developed by EBU ECM MAG

EgtaMETA schema

Based on EBUCore

Adopted by NoTube

Next step:

BXF linking

Eurovision News Exchange: IPTC NewsML-G2

EBU - early implementer

EBU played a key role in the definition of the ‘partMeta’ (video metadata)

NewsML-G2 is distributed operationally via the Eurovision network (SuperPoP).

EBU receives NewsML-G2 feeds from Reuters, AP, etc.

Future activities: semantic web combined with HMTL5 and RDFa

Acquisition Technical and Descriptive metadata

A sub-activity of the Strategic Programme HIPS

o HDTV Interoperability Production Solution

Participation: EBU members and industry

Scope: acquisition metadata (camcorders, etc.)

Current status

o Technical Metadata (camera, lens, microphone parameters)

Sony update

Technical and descriptive metadata: xml serialisation

Class Conceptual Data Model CCDM

CCDM - a common base for interoperability

Define common classes

Define common relationship

From commissioning to delivery

Other projects

EBU Class Conceptual Data Model

EUScreen and Europeana -> archives portals, EBUCore in XML and RDF

TV-Anytime (Electronic Programme Guide)

FIMS (Service Oriented Architecture)

RDF/OWL (semantic web and linked data) -> W3C, schema.org

Controlled vocabularies and classification schemes

And of course AVDP...
