2. Introduction¶

This document is designed to guide a technical or technically-minded audience into understanding, applying, and using the software system-related parts of the Gaia-X Trust Framework. This includes roles such as enterprise IT architects, software architects, technical leads, lead developers, software developers, (software) product owners, as well as project managers and technical leadership functions (up to and potentially including also CTOs, CIOs, or IT managers). Using the concepts contained in this architecture document, organisations and enterprises will be able to define and implement the technical measures necessary to create or participate in federated trusted digital ecosystems whose trust layers are interoperable with other digital ecosystems.

The document structures Gaia-X’s architectural vision across interconnected layers, beginning with the conceptual underpinnings of federated digital ecosystems and progressing to technical specifications enabling interoperable trust. Chapter 3 contextualizes the larger environment Gaia-X is operating in from a technical vantage point, including a positioning towards related initiatives and standardisation efforts. Chapter 4 outlines and explains the Gaia-X Trust Protocol, a generic specification for interoperable trust relationships across ecosystems, and the Gaia-X Trust Framework, which represents an instantiation of the Gaia-X Trust Protocol based on Gaia-X Compliance rules and Gaia-X-accredited trust service providers. These specifications enable automated onboarding, credential verification, and ecosystem services to operationalize sovereignty and compliance with business rules across distributed infrastructures. Chapter 5 details an implementation mechanism supported by the particular semantic model for data products. The complete specification of Gaia-X technical compatibility (the “heart”) is then explained and expanded in Chapter 6.

Overall, the architecture’s layered design converges towards our single vision at Gaia-X: empowering digital ecosystems with the technical and governance foundations supporting the implementation of an interoperable universal trust layer securing, amongst others, sovereignty and security for all participants and the service interactions between them.
