Lizzy Komen from the Netherlands Institute for Sound and Vision presented the "Sound Connections" social networks pilot. The pilot allows communities to explore and enrich sound collections from several cultural institutions through a social networking platform. Partners in the pilot include the British Library, Historypin, Ontotext, and the Netherlands Institute for Sound and Vision. The pilot connects thousands of audio tracks from each institution. Users can tag and comment on sounds, and cultural institutions receive notifications about user contributions. Historypin has extended the platform by allowing other institutions to host collections and by increasing scale through projects on the First World War Centenary Hub.
