Simpl‑Open is built to prevent new infrastructure silos by enabling seamless integration with other federated networks. As an open‑source, modular middleware aligned with European data‑sharing standards, it supports secure communication protocols and flexible onboarding, identity, and metadata models that can adapt to different ecosystems. This allows other federated networks to map their governance and identity frameworks onto Simpl‑Open without redesigning their infrastructure. Its replaceable, modular components and fully open‑source approach ensure transparent, flexible integration allowing networks to stay autonomous while still interoperable across the broader data‑sharing landscape. For more information please refer to Installation Guide.

SMEs can install and use the Simpl-Open as well as contribute to the code, strategy and architecture as per Contributions Guide: LINK.

SMEs can also deploy Simpl-Open to learn from it, so that joining data spaces based on Simpl-Open becomes easier.

Simpl‑Open is designed to integrate with European digital‑identity standards by supporting configurable identity attributes, onboarding rules, and secure communication protocols that can align with the eIDAS 2.0 framework and the forthcoming EUDI Wallet. This flexibility allows Simpl‑Open to interoperate with trusted digital identities issued to EU citizens, legal entities, and public administrations, ensuring secure and verifiable access to data across federated ecosystems. Its standards‑based and modular approach makes it well‑suited to adopt and interact with interoperable EUDI Wallets as they become central to Europe’s secure data‑exchange infrastructure. EUDI Wallets will be supported on Tier 1 SSI Implementation by supporting OIDC4VP.

No, Simpl is not only focused  on targeting AI factories. It exists to support common use cases for all data spaces.

The underlying framework is the W3C Semantic Web framework, mainly based on: 

• Resource Description Framework (RDF) – data representation model
• Web Ontology Language (OWL) – ontology language
• RDF Schema (RDFS) – basic schema language

The ontology file is written in Turtle syntax, which is a compact RDF serialization.

We do not view Microsoft Azure or other major platforms such as Apple, Google, or AWS as competitors to Simpl‑Open. These platforms provide infrastructure and commercial ecosystems, whereas Simpl‑Open serves as  middleware independent of infrastructure providers-infrastructure management components and operate independently of specific cloud platforms.

The continued dominance of large technology platforms in Europe does not prevent the adoption of Simpl‑Open. Instead, Simpl‑Open can complement existing ecosystems by offering an open, standards‑aligned alternative that organizations can adopt alongside their preferred commercial solutions.

In that sense, Simpl‑Open broadens the choice rather than competing head‑to‑head, giving stakeholders an additional compliant pathway that fits different maturity levels, strategies, and procurement preferences.

As a middleware, Simpl-Open does not deploy in isolation. Reaching production requires setting it up and configuring it to the specific needs of your data space, adding the relevant models and components, and integrating it with your existing IT landscape. As with any infrastructure component, validation in non-production environments before go-live is standard practice.

The current version of Simpl-Open already makes this possible. It will continue to evolve, with new components being added and existing ones improved over time.
