Partner data spaces and initiatives

In 2024, Simpl-Live completed feasibility studies with six data initiatives, Public Procurement Data Space (PPDS) , European Health Data Space for Secondary Use of Health Data (EHDS2) , Language Data Space (LDS) , European Open Science Cloud (EOSC) , Destination Earth (DestinE) , and Smart Communities Data Space (SCDS) , spanning domains such as public procurement, health, science, and smart communities. These studies explored how Simpl-Open could be integrated into these initiatives to support both internal operations and cross-sector interoperability. 

In 2025, Simpl-Live feasibility studies are expanding with five additional initiatives: Common European Energy Data Space (CEEDS) , Common European Agricultural Data Space (CEADS) , European Mobility Data Space (deployEMDS) , Green Deal Data Space (GDDS) , along with the EuroCloud initiative.

The next phase, the integration of Simpl-Open into the data spaces and initiatives assessed in 2024, began in Q1 2026, marking a major step towards operationalising Simpl across Europe’s data spaces ecosystem.

Implementation Scenarios of Simpl-Open 

Currently, there are two envisioned implementation scenarios identified by Simpl-Live for Simpl-Open: 
 

Simpl-Open to enable data space fundamental processes 

In this scenario, Simpl-Open acts as an enabler of key fundamental processes that allow a data initiative to connect to a single source and facilitate collaborations across and between data spaces, initiatives, and sectors. Simpl provides building blocks, including standards and frameworks, to enable essential internal business processes such as governance and auditability, security and compliance, data ingestion and transformation, interoperability, metadata management and discovery, and personal data handling.   

This scenario is most relevant to data initiatives with a low level of maturity that do not yet have, for example, an existing governance authority or onboarding processes. An example of a data space that would fit this implementation scenario is the Smart Communities Data Space .
 

Simpl-Open as a gateway to other data spaces and initiatives   

In this scenario, Simpl-Open serves as a gateway that allows a data initiative to connect to a single source and facilitates collaborations across and between data spaces, initiatives, and sectors. Simpl focuses on enabling interoperability, cross-sector collaboration, and compliance and security within and between the different data spaces.   

This scenario is most relevant to data initiatives which have reached a higher level of maturity, meaning that are already operational and have existing structures and procedures in place. Examples of data initiatives that would fit this implementation scenario are the Public Procurement Data Space , Destination Earth , and the European Open Science Cloud .   

It is important to note that these two implementation scenarios can be viewed as two ends of a spectrum, from less mature to fully mature data initiatives, and that several data initiatives fall in the middle of this range. The Language Data Space and the European Health Data Space for secondary health data use are examples that lie between these two ends of the spectrum.
