# System Architecture

The system architecture has been described in depth in two project deliverables:

* D5.1 High-Level Design of the Data Fabric (add link)
* D5.2 Low-Level Design of the Data Fabric (add link)

It follows a modular approach and builds on open standards and open-source software components.

The backend consists of

* pygeoapi to provide data and processing capabilities
* GeoServer to provide data
* Custom data ingestors

The frontend is implemented using [Open Pioneer Trails](/data-fabric-manual/adding-and-developing-features/introduction-to-open-pioneer-trails.md), an open development platform for web clients that enables the development of custom GeoIT solutions.

Please note that reproducibility of the platform is limited once external data sources are altered.
