The INSPIRE register federation is a distributed federation of registers related to the INSPIRE Directive.

The European Commission is operating a (central) registry providing common INSPIRE registers, e.g. to manage INSPIRE code lists or themes. Where Member States extend these code lists, they are obliged to make available the extended values in local registers. Such local registers can also support other use cases, e.g. the management of organisations in a country that have to implement INSPIRE, or thematic vocabularies, such as those provided by EU institutions and bodies.

The Re3gistry is a reusable open source solution for managing and sharing ‘reference codes’, ensuring concepts are correctly referenced in INSPIRE, or for content in any other sector.
