This document summarizes the work of WP2 on TV Metadata Interoperability in the NoTube project. Key achievements include developing mappings between various metadata formats like egtaMETA, PrestoSpace, BMF, and TV-Anytime. Evaluations ensured consistency in metadata transformations between formats. A BMF Ontology was also generated to provide semantic access to metadata. Lessons learned include that existing metadata models can achieve interoperability needs and linking metadata to the LOD cloud via open standards allows new applications.

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 Ontology
26-27 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-NIC

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 permissions

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 distribution

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)

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…
