EBUCORE


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 – Why and when


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 – EBUCore: schema choices


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

EBU Technical – What makes EBUCore Unique?

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: Distribution


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?

EBU Technical & metadata: Recent Results


WHAT’S NEXT?

EBU Technical & metadata: Towards...


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

EBU Technical & metadata:

The EBU class model: Media



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 Classification schemes

Genre

Role

Etc.

Already translated in SKOS (concept class)...

EBU Technical & metadata: Classification Schemes


WITHIN THE NEXT FEW WEEKS...


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
