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
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. You can leave
your comments at the end of this article for feedback. 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.
2. EUscreen signs Europeana’s new Data Exchange Agreement
A second, and related, development is EUscreen’s recent signing of
Europeana’s new Data Exchange Agreement, which ensures access and
enlarged user involvement with the materials published on the platform.
The agreement replaces the current Data Provider and Data Aggregator
Agreements and governs what Europeana may or may not do with the data of
the different aggregators through its web activities.
The Agreement will come into force on January 1, 2012, but EUscreen is
proud to be at the forefront and one of the early adopters in this bold
step forward for opening European cultural heritage to wide audiences.
>From the Europeana office: The Europeana Data Exchange Agreement is
the result of a year-long process of consultations with the whole
network of content providers and aggregators contributing to Europeana.
The results of these consultations and other documentation can be
found on the Europeana Towards a New Agreement pages.
