Who are we?

The Gaia-X European Association for Data and Cloud AISBL represents the core of the organisational structure. It is an international non-profit association under Belgian law (French: association internationale sans but lucratif, shortened to AISBL). It was founded to develop the technical framework and operate the Gaia-X Federation services.

Officially, the Association was founded by 22 companies and organisations in January 2021. Until today, over 340 members have joined and more are welcome. Its members are committed to upholding the values of data protection, transparency, openness, security, and respect for data rights. They are either companies with a provider or user background of data infrastructures, IT-start-ups, research institutions or business associations.

The Association has no business interest of its own. It will develop federation cloud services within the existing cloud infrastructures. To achieve this and to ensure an open and transparent character the Association facilitates the development of an open software infrastructure.

What we do ?

The Gaia-X Association will develop policy and rules, technical and regulatory frameworks to ensure that the necessary central facilities as well as key federation services guarantee the envisaged data infrastructure are made available.

The activities of the Gaia-X Association are based on three main objectives:

Specify – Architecture and Federation Services specification

Federation Services are the minimum technical requirements and services necessary for the operation of federated Gaia-X ecosystems. They connect the infrastructure and the data ecosystem. The Association will document, describe and validate the key ‘Federation services’. The AISBL will publish a ‘reference architecture’ which contains all existing and applicable existing standards, depicting the meta-model and the deployment of software components constituting it. In addition, AISBL will publish the specification of the federation services.

Implement – Open-source software code

The ‘reference architecture’ and the federation services specified by the Gaia-X Association need to become operational in practice. For this reason, the Gaia-X Association will develop an open-source ‘reference implementation’ (software code) based on the federation service specification.

Test – Instruments of certification

Each implementation based on the reference implementation of the Gaia-X Federation Services used in cloud/edges needs to be tested. The Gaia-X Association will provide guiding principles for an automated ‘conformity test’. The conformity check will validate the regulatory design and the correct implementation of the software.

Organisational structure

The Gaia-X Association’s General Assembly is composed of all of its members. The General Assembly has complete authority to carry out the objectives of the Gaia-X Association

The Board of Directors decides on important matters regarding the Gaia-X Association. It is headed by a Chairperson and Vice-Chairperson.

The Management Board manages the daily activities of the Gaia-X Association. The Management Board is composed of the Chief Executive Officer (CEO), the Chief Operating Officer (COO), the Chief Technical Officer (CTO), and the Chief Marketing Officer (CMO).

Committees & Working Groups

Data Spaces Business Committee (DSBC)

The Data Space Business Committee is driven by a business ecosystem and strives to proactively support the creation of Data Spaces by third parties across Europe and beyond.

The DSBC collects and prioritises economic, functional, operational and legal requirements and promotes a level of standardisation that facilitates seamless collaboration and interconnection between Data Spaces, Lighthouse Projects and Hubs.

The DSBC also supports the link with the Ecosystem Verticals.

The working groups currently active within the DSBC, are the WG Governance, WG Finance, WG Operational Requirements, WG Technical and WG Hubs.

Among the main deliverables of the DSBC are the Handbook for Gaia-X data spaces (WG Governance), the  Handbook ’Business models for and with Gaia-X data spaces’ (WG Finance), the Cataloguing of existing data space technologies (WG Technical) and the Hub Handbook (WG Hubs).

Lead and Vice-Lead: Sebastian Schlosser (BMW), Thomas Hahn (Siemens)

For more information, please reach out to: Giuditta Del Buono 

Working Groups

The group is responsible to define the Handbook of the Gaia-X-data spaces, which is expected to be initially released by July 2022. The document collects contributions from the other WGs that are active under the DSBC, especially the Finance and Technical WGs, and will help data spaces to define their own structure from a business, functional, technical and legal point of view.

In order to define the Handbook, the group is working on a paper to define Governance as this would apply to data sharing initiatives, and representing the landscape of existing items, needed items and associated stakeholders related to Governance, analysing both Gaia-X and other initiatives in relation to data sharing. Furthermore, the WG has developed a questionnaire proposing to various data spaces initiatives to gather input on existing practices and needs in terms of Governance.

Lead: Lars Nagel, CEO International Data Spaces Association

For more information, please reach out to: Giuditta Del Buono

The WG aims to identify business models and value propositions related to the data spaces ecosystems, based on players role, data space types, operational models and types of data exchanged.

This work will converge in the ‘Business models for and with Gaia-X data spaces’ Handbook, which is expected to be published by July 2022.

The group is analysing concrete examples from existing initiatives, which will be reported in the Handbook to ensure that the readers, both decisions makers and people involved at a more operational level, get an understanding of why Gaia-X data spaces are needed and represent an added value for the companies’ business, compared to the use of the classic platform and digital marketplaces.

Through a collection of practical use cases, the benefit for companies in sharing data and cooperating within a data space will be represented.

Lead and vice-lead: Dominique Epardeau (EONA-X), Hilko Hoffmann (DFKI)

For more information, please reach out to: Alessandra Perna

The group drafts the operational, compliance, regulatory and legal requirements for Data Spaces. These will be transferred to the PRD and Labels & Qualification WGs to define their respective deliverables.

For this purpose, the group identifies & defines the minimum technical, legal, regulatory, and operational attributes of any data sharing Gaia-X event.

Finally, it provides the WG Compliance contract templates, and the minimum contractual requirements between data supplier providers and data recipients, under the different use cases (B2B, B2C, B2B2C, C2B, C2G, B2G, G2B, etc).

Lead and Vice-Lead: Rebekka Weiß (Bitkom), Isabella De Michelis (ErnieApp)

For more information, please reach out to: Giuditta Del Buono

The group is also conducting a collection of use cases coming from National Hubs and is cooperating in streamlining the process to get requirements from Hubs, providing at the same time information to Hubs to support them in developing use cases and business cases.

Lead and vice-lead: Peter Kraemer (Acatech), Jelle Hoedemaekers (Agoria)

For more information, please reach out to: Alessandra Perna

Policy Rules Committee (PRC)

The Policy Rules Committee (PRC) aims to translate the guiding principles of the Gaia-X initiative, e.g., transparency, data protection, cyber security, portability, and openness, into High-Level Objectives to safeguard the added value of the Gaia-X ecosystem.

Furthermore, the PRC has the role to monitor, integrate and define the relationship with EU regulations and external standards.

Specifically, the Committee guides and delivers the Gaia-X Policy Rules Document, the Gaia-X Trust Framework, the Gaia-X Labelling Framework and the Gaia-X Labelling Criteria , and as these are prepared in collaboration with the three related working groups: PRD, Compliance, and Labels & Qualification.

Lead and Vice-Lead: Ulrich Eichhorn (Volkswagen), Frédéric Etheve (OVHcloud)

For more information, please reach out to: Giuditta Del Buono

Working Groups

The group works on the Gaia-X Labelling Framework and Gaia-X Labelling Criteria documents, in close alignment with the Policy Rules and Compliance working groups and the three Gaia-X Committees.

The Labels aim to increase trust in services with regard to the implementation of European values and standards. They are issued for Service Offerings, are optional and built on top of the Trust Framework, which represents the reference for Gaia-X compliance.

The Gaia-X Labelling Framework defines the Labelling principles and the three levels for the Gaia-X Basic Label, based on criteria related to data protection, transparency, security, portability and flexibility, and European control.

Further labels, sector or country-specific, can be built on top of these three basic labels and owned by different subjects.

The criteria are listed in the Gaia-X Labelling Criteria document, whose first version has been defined also by analysing and working on the comments collected through a survey addressed to all Gaia-X members.

The cooperation of the Labels & Qualification and the Policy Rules WG is focused on the representation, within the Labels, of the High-Level Objectives listed in the PRD, and provides inputs to the PRD. The collaboration with the WG Compliance is related to the implementation of Labels, and as this would relate to the detail of criteria and the identification of entities accredited by Gaia-X  to support the verification process.

The group equally implements the Labels, together with the Gaia-X Lab and the accredited entities. The first Labels are expected to become operational by 2022.

Lead and Vice-Lead: Martine Gouriet (EDF), Martin Chapman (Digitaleurope).

For more information, please reach out to: Giuditta Del Buono

The group is responsible to finetune and keep up to date the Gaia-X Policy Rules Document that sets out the High-Level Objectives reflecting the values and principles of the Gaia-X ecosystem, and as these would relate to openness, transparency, data protection, security, and portability.  The document derives from the Gaia-X Vision & Mission.  It takes into account external legislation and certification schemes, as well as feedback collected through public and members consultations.  It will be regularly updated.

The Policy Rules Document is drafted in close alignment with the working groups: Compliance and Labels & Qualification, respectively owners of the Gaia-X Trust Framework and Gaia-X Labelling Criteria, where the criteria, the actual requirements and the corresponding control measures related to Gaia-X Compliance and Gaia-X Labels are specified.

The WG PRD is under the responsibility of the Policy Rules Committee.

Lead and vice-Lead: Bert Verdonck (Philips), Lorelien Hoet (Microsoft)

For more information, please reach out to: Giuditta Del Buono

The group owns the Gaia-X Trust Framework, which represents the reference document for the Gaia-X compliance, providing the compulsory set of rules of the Gaia-X Ecosystem.

Those rules ensure a common governance and the basic levels of interoperability across individual ecosystems, while allowing the users to be in full control of their choices.

The Trust Framework is drafted in close alignment with the Gaia-X Policy Rules Document, the Gaia-X Architecture Document and the Gaia-X Labelling Framework.

Together with the definition of the measurable and comparable attributes, which raise the level of trust, create awareness, and reduce the risks of participant decision making, the Trust Framework contains the list of Trust Anchors – the Gaia-X endorsed entities that manage the certification process to sign claims.

The group evolves the automated validation of claims and cooperates with the Gaia-X Lab to implement the Trust Framework.
