About The Re3gistry


Back to ARE3NA landing page

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. ARE3NA is currently working with software users and Member States to make improvements and create a federation of registries for use in multiple information systems.

The Re3gistry development continues under the ISA2 ELISE action. Visit here the new space

Work package 6 “Registers”


Authoritative reference codes need to be provided in an open and consistent way so that they can be readily reused in information systems. These can be seen as key ‘semantic assets’ that enable data interoperability by clearly referring to concepts. Lists that provide unique identifiers for such items, together with the items’ descriptions, are referred to as registers, and the systems and software that support the management of registers are known as registries.

An online tool, the INSPIRE registry service, was needed to share such the codes in INSPIRE’s reference registers and make these assets available for not only information systems but also any sector to view and reuse as core material for data covered in the INSPIRE Directive’s thematic annexes.

The solution powering the INSPIRE tool, the re3gistry, licensed under the EUPL,  has been developed in a context neutral way as an open source project, so that it can be deployed or further developed for any sector wanting to have authentic reference data/codes made available for information systems and human users.

Nowadays, ARE3NA is still improving the software and in parallel, it is supporting the study and the implementation of the “Federation of registries”, another missing item in the software market. This feature will allow registering extensions and other externally governed references codes so that they can be traced and reused by a bigger audience.
