26-27 March 2012 NoTube 3rd review

Technical Achievements Y3

• Integration of metadata conversion and access services with Use Case partners (in iterative process)

• Modifications of mappings and services according to evaluation reports

• Update of metadata formats – BMF 1.2 BMF 2.0 (2012)

– TVA 1.4.1 TVA 1.7.1 (2011)

• Generation of a BMF Ontology


Detailed Evaluations

• Objective: ensure consistency in metadata transformations • Second evaluation in Year 3 (based on Year 2 evaluations):

– Re-run of evaluation by inspection for modified egtaMETA2Tva with new test instances from EBU (TVN)

– Evaluation PrestoSpace2Tva through service integrator (RAI)

• Detailed reporting – In internal reports – summary in D2.4

• Bug fixing – In close collaboration with EBU for egtaMETA2Tva conversion – required specific mappings for PrestoSpace RAI-NIC


Professional TV Metadata - going semantic…

• 3 years ago: semantic applications was no topic for most broadcasters

• Today: more awareness for web applications, smart tools for media production etc.

• Input from NoTube: access to the rich production metadata available at broadcasters (from internally and externally) requires structures and permissions


Why BMF?


Abstract semantic model

Designed for metadata exchange in the

professional media production

Also useful for applications in the distribution area

Restrictive but flexible model

Usable as XML Schema

Possible database baseline …or OWL

Will be used by ARD for the exchange of information for

programmes distribution

BMF-OWL

• Use of Semantic Web standards to provide access to the semantics of BMF metadata for Semantic Web applications

• Translation of BMF model into an OWL ontology with support from VUA

• Metadata documents need to be connected with the BMF ontology to query the information: BMF-XML RDF (using XSLT)


BMF-OWL

BMF XML Schema

BMF Ontology (OWL)

Summary + Lessons Learned

• TV metadata interoperability achieved with existing metadata models/formats

• TV-A supports all elaborated requirements • Specific mappings required to solve remaining

issues • BMF-OWL allows provision of TV metadata in an

open standard machine readable and Semantic Web compliant metadata allows linking to the LOD cloud

• Several sustainable results achieved…


WP Results (1/2) – Life after NoTube

• Metadata Mappings: – egtaMETA TVA 1.4.1

– PrestoSpace BMF 1.2

– PrestoSpace BMF 2.0

– BMF 1.2 TVA 1.4.1

– BMF 2.0 TVA 1.7

– TVA 1.4.1 RAI-NIC

– TVA 1.7.1 BMF 2.0

– BMF 2.0 BMF-OWL

• All available at www.notube.tv

WP Results (2/2) – Life after NoTube

• Extension of Metadata API – Import and export of BMF data supported

• Conversion Services – Metadata mappings implemented as loosely coupled software components – Implemented as web service – Service used in UC 7a demonstrator

• CRUD Service – Data manipulation of news-related metadata – Implemented as web service – Service used in UC 7a demonstrator – Service also used for Loudness Normalisation
