The INSPIRE infrastructure involves a number of items, which require clear descriptions and the possibility to be referenced through unique identifiers. Examples for such items include INSPIRE themes, code lists, application schemas or discovery services. Registers provide a means to assign identifiers to items and their labels, definitions and descriptions (in different languages). The INSPIRE registry provides a central access point to a number of centrally managed INSPIRE registers.

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.
