Layers of data space governance

The layers of data space governance (Figure 4) are inspired by the Design Principles for Data Spaces[^7] publication. This was developed in the context of the OPEN DEI project funded by EU where data spaces experts teamed up to define cross-sectoral principles for building data spaces.

Layer​	Description​
Data space instance governance	Executes and implements the governance practices and rules of a data space instance. Oversees data space functions and the rules.​
Data space ecosystem governance​	Defines the rules for the data space instance. Creates the intra data space trust between collaborating organizations. Complements standardization and regulation focusing on business-driven rules. Defines the inter data space interoperability practices.​
Data space domain governance​	Establishes sector-specific data space principles and mechanisms including semantic interoperability and domain-specific regulation. Leaves room for geographical differences while supporting maximum interoperability.​
Soft infrastructure governance​	Brings all the generic data space building blocks and concepts together, defines the legal basis and creates the common framework on which all data spaces are built.​
