Joinup is a collaborative platform created by the European Commission and funded by the European Union via the Interoperability Solutions for Public Administrations (ISA) Programme.

Joinup offers a set of services to help e-Government professionals share their experience with interoperability solutions and support them to find, choose, re-use, develop and implement open source software and semantic interoperability assets. 

The following six services, as indicated in the screenshot below, are the core services of Joinup.
