Linked data and applications
The document discusses the BBC's efforts to publish structured data on the web using semantic technologies. It summarizes their work to publish program and music data as linked open data using URIs and ontologies. This includes publishing data about TV and radio programs, music artists, and linking the data to external sources like MusicBrainz and DBPedia. It also discusses applications that can query and visualize this linked data, as well as next steps to publish additional BBC topic data and develop applications to leverage the web of linked data.
