Technical interoperability

The technical interoperability of the Findynet network is ensured by means of interoperability profiles. The profiles define the standards and functionalities with which the software of the different actors must be compatible.

The interoperability profiles for the Findynet network have been defined by the Findynet Cooperative Technology Working Group and approved by the Cooperative Board. The interoperability profiles are updated as needed.

Software used by actors in the network must comply with the following profiles:

The OpenID Federation protocol is used to identify network members and define their rights..

Each ecosystem selects its profile based on its specific needs, with assistance from Findynet. The interoperability profiles serve as annexes to the network rulebooks.

When a new version of an interoperability profile is released, Findynet’s technology working group analyzes the changes and sets a deadline, at least six months in the future, by which compatible systems must support the new version.

Findynet collaborates internationally to promote test frameworks for interoperability profiles.

DIIP and HAIP are not conflicting but rather complement each other. Both aim for interoperability with the technical implementations related to the eIDAS regulation. DIIP ensures practical interoperability by selecting the draft versions of each of the specifications currently in use. HAIP will further clarify the open issues in the specifications by making choices that will allow in particular the use of natural person identifiers in wallet applications.

DIIP v3

The responsibility for maintaining the DIIP profile has been transferred during 2024 and the latest specifications have yet to be published in an official repository. The latest officially released version is DIIP v2, published on January 1, 2024.
However, a newer version, DIIP v3, has already been defined and was utilized in interoperability tests during the FIDES Plugfest #1 event in the fall of 2024. Therefore, version 3 will also be used in the Findynet network trials. The standards it adheres to are:
