DESCRIPTION: Open data refers to the practice of publishing (raw) data in a way that is accessible, reusable, machine readable and licensed permissively. It can be generated by a wide range of parties, including public authorities, the semi-public sector, businesses and the public. In the case of public authorities, such as European Union organisations, making their data available for public reuse supports economic development, openness and transparency.

Opening of public sector datasets for sharing and reuse is encouraged by the Directive on the reuse of public sector information, which provides a common legal framework for reuse of public sector data as stated in the EIF recommendation n° 2: "Publish the data you own as open data unless certain restrictions apply." EXAMPLES: The following implementation is an example on how this specific Architecture Building Block (ABB) can be instantiated as a Solution Building Block (SBB): European Data Portal The European Data Portal harvests the metadata of Public Sector Information available on public data portals across European countries. Information regarding the provision of data and the benefits of re-using data is also included. Within the Portal, sections are dedicated to: • Searching datasets: Categories have been established to structure the metadata harvested from the various countries. These categories follow the revision of the DCAT Application Profile and have been mapped against the Eurovoc Thesaurus. • Providing Data: This section gives an insight into understanding Open Data from the perspective of a data provider. In addition, instructions are offered for those who wish their data portal to be harvested by the European Data Portal. • Using Data: How Open Data is being used, as well as the economic benefits of Open Data are detailed in this section. • Training and Library: eLearning modules about Open Data as well as training guides and a knowledge base referencing publications around Open Data and featured projects. Portals can be national, regional, local or domain specific. They cover the 28 EU Member States, EEA, countries involved in the EU's neighbourhood policy and Switzerland. https://www.europeandataportal.eu/
