EU: TV Archives Join Linked Open Data Movement

Posted on September 29, 2011 by


From the British Universities Film & Video Council (BUFVC):

The EUscreen project has recently taken steps to expand the scope of its aim to provide unified access to large integrated digital collections related to European television history.

By implementing the Linked Open Data principles and by signing the new Europeana Data Exchange Agreement, the materials that are made accessible through the platform have become more widely searchable, findable, linkable, and thus more connected to the world wide web, its users… and the machines that link them together. Information about EUscreen’s Linked Open Data Pilot can be found at http://lod.euscreen.eu

EUscreen opens up to Linked Open Data

On the EUscreen platform, 27 partners (broadcasters, archives and universities) select, curate and provide television materials from their rich vaults that together hold a great part of European audiovisual history. By mapping the schemata that underpin their content descriptions to the EUscreen metadata model, content providers ensure greater visibility and findability of their content in the public realm. Much work has been done on uniformly processing the different metadata models to one central EBU Core-based model. This model ensures a level of uniformity that surpasses the scattered databases that the different institutions work with. The integrated collections are published on the EUscreen portal and from there on aggregated by Europeana.

With this centralised model in place, it was a relatively straightforward step to implement the Linked Open Data principles, which permit the interpretation and interlinking of the data to various sources outside of the EUscreen domain, and allow for a machine-readable level of access to the content. EBU Core provides mappings to all known audiovisual metadata standards, including the W3C’s Media Annotation ontology.

The EBU Core ontology was used to formalise the metadata in the Resource Description Framework (RDF) format and publish them as Linked Open Data.

Johan Oomen, technical director of EUscreen, and Vassilis Tzouvaras, leader of the work package on portal architecture, wrote a paper on the installation of the Linked Open data model: Publishing Europe’s Television Heritage on the Web (PDF). In it, the authors describe how this fits in within the larger technical challenge of creating the different components that make up the EUscreen ingestion workflow. The paper describes the reasoning behind the workflow, the set-up and overview of the process and how these technical developments improve access to our shared television histories to students, teachers and the general audience. The authors would like to acknowledge EUscreen consortium partner EBU, specifically mr. Jean-Pierre Evain, for their work in the area of multimedia semantics and Linked Open Data, as their EBU Core Metadata Set has been used to ensure semantic interoperability within EUscreen and beyond.
