DESCRIPTION
NPOs and NGOs are acting more-and-more as open data providers for various stakeholders like citizens, enterprises and communities. Linked open data becomes a key concept to meet several demands of information professionals, for instance interoperability and accessibility of data, multilinguality and harmonisation of metadata. The open data value chain is about to change from a rather simple to a more complex network of data streams which produces new revenue models and more differentiated roles – linked open data plays a central role in this development. This webinar is about the use of linked open data and controlled vocabularies in the specific enviroments, NGOs and NPOs are working in. Get an overview about the underpinning motivation and concepts which drive the very concrete use cases which will be presented:
