# Introduction According to the DSSC description, 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, trust, and interoperability across the ecosystem. The purpose of these building blocks is simple: * Help data spaces identify what’s needed. * Point to common standards, specifications, and proven solutions. * Make it easier to reuse, connect, and interoperate without reinventing the wheel. This way, participants reduce complexity, speed up adoption, and support interoperability both within and between data spaces. Similar to DSSC components, iSHARE groups these capabilities into three pillars: Technical capabilities are structured according to [three pillars](https://blueprint.dssc.eu/?pane=technical#TechnicalBuildingBlocks-2.Overviewofpillars): 1. **Data Interoperability**: agreeing on how data is described, formatted, viewed, and exchanged across different data ecosystems. This also includes recording provenance, traceability, and observability when necessary. 2. **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. 3. **Data Value Creation Enablers**: describing, publishing, and discovering data, services , and offerings so participants can build use cases and generate value together. Through these building blocks, other participants can work together to define the technical rulebook of a specific data space. {% hint style="info" %} See the complete DSSC description [here](https://blueprint.dssc.eu/?pane=technical). {% endhint %} --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://template.ishare.eu/technical-building-blocks/introduction.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
