  • 23. NoTube Impact Factor • Impact on standards and tech communities: • Showcase proving the use of egtaMETA (A set of semantically defined attributes considered to sufficiently describe advertising material) [http://tech.ebu.ch/egtameta] • Further prove that the use of Semantic Web technologies (like RDF, OWL, etc.) is beneficial in domains with complicated data structures and hard to come by metadata • Further support to the TV-Anytime specification, describing audiovisual content • Extra showcases and requirement specifications as input to the HbbTV consortium (e.g. apps, profiling, recommendations, data enrichment, etc.) • Proving the use and benefits of the social TV concept to a broader audience Stoneroos Interactive Television www.stoneroos.com26-27 March 2012 NoTube 3rd review 23

  • 25. Learned during NoTube • That besides the proven advantages of the linked open data approach, also some challenges emerge with respect to the size of the data sets and how to retrieve the necessary information in a quick and responsive way • There is a clear difference between requirements set by a customer who knows what he wants and requirements at the start of a research project. For the latter, during the course of a project technology continues to evolve which can lead to new ideas/insights (e.g. emerge of the tablet) • During NoTube we gained a great deal of knowledge concerning apps development and business models on both mobiles, tablets and connected TVs • The fact that personalization and providing recommendations on a TV platform is still a challenging and mind-breaking issue Stoneroos Interactive Television www.stoneroos.com26-27 March 2012 NoTube 3rd review 25
