BBs are common open-source digital resources designed to provide well-defined services that facilitate the exchange of reliable data. Categories: Core components (Catalogue [6.1], Contract [6.2], Consent [6.3]), Utility (DVCT [7.0]), Trustworthiness and Data transformation.

The building blocks are common open-source digital components designed to provide well-defined services that facilitate the exchange of trusted data within the dataspace. These blocks act as modular pieces that allow to build and operate interoperable, federated and trust-based data infrastructures. Their main goal is to reduce the technical and organizational complexity that the information exchange carries between multiple organizations and, at the same time, guaranteeing security, governance and compliance with applicable regulations. As they are open-source, Building Blocks foster collaboration and standardization, what facilitates the deployment of data spaces at a sectorial and transnational level.

Building Blocks cover essential basic tasks throughout the entire lifecycle of the data: from data publication, discovery and access to usage, transformation and accountability assessment. They are aligned with the key principles such as:

• Data sovereignty, that allow data owners to maintain control over their data).
• Transparency, to know how data is used and transformed.
• Interoperability, to ensure different systems can understand each other.
• Regulatory compliance, especially in contexts regulated by GDPR.

In a dataspace, these blocks are organized in practical categories that gather services with similar goals:

• Core components: this category gathers the basic components that make the data space work in a structured and secured manner. This includes:
  • Catalogue [6.1]: is the component that is in charge of registering, describing and publishing the data and services available in a data space.
  • Contract [6.2]: is the component in charge of the management that regulate the data exchange between organizations.
  • Consent [6.3]: is the component that allows the management of the consent and the licenses of the data especially in personal data scenarios.
• Utility: that includes support components, such as DVCT [7.0], that can track the data value chain, its origin, transformation and usage, contributing with transparency and traceability.
• Trustworthiness: includes services oriented to ensure liability, integrity and data quality and their associated processes, increasing participant’s trust.
• Data transformation: includes components that transform, armonize and enrich data, allowing interoperability, data sovereignty and use cases.

Overall, these building blocks create a modular and reusable foundation to build trusted and scalable data spaces, aligned with the interoperability, data sovereignty and transparency principles, knowing its purpose, duration and scope, and with the possibility of revoking that consent at any time.
