EXPERT COMMUNITY METADATA

EBU Technical – ECM, to the benefit of all

Our first customers: EBU members and EBU SPs and Ecs

Others users: other audiovisual communities

Our focus: technologies supporting EBU member services

External expertise is welcome: reinforcing our resources

Sharing knowledge and experience


EBU Technical – ECM domains of expertise

To keep experts‟ interest and focus for better contribution

 Representation of data

 Generation of data

 Indexing and retrieval

 Workflows and Lifecycle of data


EBU Technical – ECM, who can join?
Anyone interested in metadata in the context of broadcasting
including broadcast, broadband, mobile and hybrid delivery.

Experts from the audiovisual sector are encouraged to join.
You are also welcome if you are keen to learn or be kept
informed.

Open to non-members !

We want this to be an open expert community !
Only constraint: a participation agreement for legal purpose
(some strategic projects may have additional restrictions)

EBUCORE


EBU Technical – Why and when
1998 – Project started on minimum metadata set
2000 - EBUCore for radio archives (DC) – no schema
2006 – Media group issued new requirements
 Not only archives
 More than Dublin Core needed
2007 – Europeana ESE -> Dublin Core mapping
2008 – EBUCore augmented and re-published with schema
 W3C mapping
 EUScreen
 egtaMETA
 SMPTE Common Core
2010 – Revised version before the end of the year

EBU Technical – EBUCore: schema choices
Facilitate DC mapping
 Schema is based on extended DC terms
 DC relations have been adopted
 Open issue: transfer structured additional information in „DC bags‟

Integrate additional broadcaster requirements
 E.g. in „format‟ and „type‟

Implement, map and improve
 W3C
 EUScreen
 egtaMETA
 SMPTE


EBU Technical – What makes EBUCore Unique?
Well defined semantics

The use of types: title type, description type, etc.

A well defined and extensible set of technical metadata
 Video
 Audio
 Captioning
 And the technical attributes to be user defined (using type)

Well defined and identified classes: semantic web ready!
 EBUCore is also a core set of data and object properties


THE METADATA ICEBERG


EBUCore – the tip of the iceberg


ECM zone of influence


EBU Technical & metadata: production
Metadata Advisory Group
1.P-META toolbox
2.Exchange Metadata
3.Music Reporting
4.EBU Core
5.Classification schemes
 Genre, role, etc.

Automatic Extraction Project
1.Library of test material egatMETA –
Tech 3340
2.Common metadata format
3.Ground truth material
4.Request for Technology
5.AIEMPro workshop

EBU Technical & metadata: Distribution

TV-Anytime (and related DVB specifications)
 EBU Technical maintaining the specification since 2005
 UK ConnectedTV, BBC Push-voD
 EC NoTube, DLNA/UPnP, MPEG, etc.

RDF/OWL (semantic web and linked data)
 EBU Technical -> EBUCoreTVA, NewsML-G2 and CSs
 Next steps: „triple stores‟, linked data and HTML5/RDFa
 Linked data quality and persistence issues

W3C MAWG, HTML5 and accessibility
 EBU Technical -> mapping to EBUCore, TV-Anytime and NewsML-g2
 EBU Technical -> Actively contributing to the W3C semantic model (RDF)


EBU Technical & metadata: Recent Results
HIPS-META – acquisition metadata
 Participation: EBU members and industry

 Metadata for camcorders, live cameras and lenses

 Agreement on technical and descriptive metadata
egtaMETA
 egta: Association of Television and Radio Sales Houses
 Schema for file exchange of advertising spots
 Based on EBUCore
IPTC newsML-G2
 Started to work on a class model
SMPTE Common Core
 Harmonisation with MovieLabs and PBCore?


WHAT’S NEXT?


EBU Technical & metadata: Towards...

Courtesy Dr. L.Obrst (Mitre), M.Davis (Project10X)

EBU Technical & metadata:
The EBU class model: Media

Why is this important?
1. It is one step into more advanced modelling and metadata representation
2. High level of interoperability with EBU members solutions & IPTC, W3C, MPEG, etc.
3. This is „semantic web‟ ready -> add data & object properties


The EBU class model: Delivery


The EBU class model: Non-media


An EBUCore/W3C class model


EBU Technical & metadata: A TVA class model


EBU Technical & metadata: A NewsML-G2 class model


EBU Technical & metadata: Classification Schemes
EBU Classification schemes
 Genre
 Role
 Etc.

Already translated in SKOS (concept class)...


WITHIN THE NEXT FEW WEEKS...


EBU Technical & metadata
EBU Object model
 Complete with class definitions and data/object properties
IPTC
 SubjectCodes translated to SKOS
 Next step: object model
 Meeting next week in San Francisco
SMPTE Common Core
 Meeting next week in los Angeles
 Other participants: MoviesLabs, PBCore, etc.
EC-M survey: join EC-M and fill the survey
First EC-M F2F meeting: October 2010

CONCLUSION


EBU Technical & metadata: Conclusions

You should now know the EBU better

Please consider joining the metadata expert community EC-M

EBUCore is open, easy, flexible, scalable and customisable

EBUCore is just the tip of the metadata iceberg

Semantic web, linked data and RDF is the future
