  • 1. WP 2TV Metadata Interoperability Peter Altendorf, IRT with BBC, TVN and Polymedia
  • 2. Outline• Technical achievements in year 3• Evaluations• Dissemination• Summary and Lessons Learned• List of WP Results26-27 March 2012 NoTube 3rd review 2
  • 3. Introduction Produced by Kerry O’Connor and Robert A. Arkeilpane at IRT in collaboration with the University of Cincinnati/Munich Summer Curriculum 2011 at Ludwig-Maximilians-Universität (LMU) München.26-27 March 2012 NoTube 3rd review 3

  • 5. 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 Ontology26-27 March 2012 NoTube 3rd review 5
  • 6. 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-NIC26-27 March 2012 NoTube 3rd review 6
  • 7. 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 permissions26-27 March 2012 NoTube 3rd review 7
  • 8. Why BMF? Designed for metadata Abstract semantic exchange in the model professional media production Restrictive but Also useful for flexible model applications in the distribution area Usable as XML Schema Will be used by ARD for Possible database the exchange of baseline …or OWL information for programmes distribution26-27 March 2012 NoTube 3rd review 8

  • 11. 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)26-27 March 2012 NoTube 3rd review 11

  • 17. 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…26-27 March 2012 NoTube 3rd review 17
  • 18. 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.tv26-27 March 2012 NoTube 3rd review 18
  • 19. 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• Services available at http://notube.irt.de:8080/NoTube-IRT-Services/services/listServices http://demos.polymedia.it/Notube/Egta2TvaConversion/services/Egta2TvaCo nversionWebService?wsdl26-27 March 2012 NoTube 3rd review 19
