# Introduction

According to the [DSSC Description,](https://dssc.eu/space/BVE2/1071254703/Technical+Building+Blocks) to make a data space work in practice, you need more than governance and legal agreements; you need the technical capabilities that bring them to life. These capabilities, or “building blocks,” provide the tools that every participant can rely on to ensure consistency and trust across the ecosystem.

The purpose of these building blocks is simple:

* Help data spaces identify what’s needed.
* Point to common standards and proven solutions.
* Make it easier to reuse, connect, and interoperate without reinventing the wheel.

This way, participants reduce complexity and speed up adoption.

Similar to DSSC components, iSHARE groups these capabilities into three pillars:

Technical capabilities are structured according to three pillars:

1. [Data Interoperability](https://dssc.eu/space/BVE2/1071255207/Data+Interoperability): Agreeing on how data is described, formatted, viewed, and exchanged across different data ecosystems. Also, recording provenance and traceability when necessary.&#x20;
2. [Data Sovereignty and Trust](https://dssc.eu/space/BVE2/1071255699/Data+Sovereignty+and+Trust): making sure participants and their assets can be reliably identified, trusted, and given the right level of access and usage control.&#x20;
3. [Data Value Creation Enablers](https://dssc.eu/space/BVE2/1071256290/Data+Value+Creation+Enablers): describing, publishing, and discovering data and services so participants can build use cases and generate value together.&#x20;
