# SATRE Architecture

The current version of the architecture can be viewed [here](https://satre-archimate.readthedocs.io/en/latest/?view=id-4349bc52159b48e9b785e9809a876c03).

This Standard Architecture for Trusted Research Environments (TREs) provides a comprehensive high-level architecture for research organisations handling sensitive data safely.

The architecture is documented using the [ArchiMate](https://pubs.opengroup.org/architecture/archimate3-doc/) modelling language with models created using the open source modelling tool [Archi](https://www.archimatetool.com/).

Capabilities an organisation requires to run a TRE are documented and deconstructed to show the elements (Roles, processes, applications and data) needed to realise those capabilities.

The architecture and SATRE standard maps to the architecture meta-model below.

Views are provided aligned to the capabilities and additional views show alignment with external frameworks such as the [Five Safes](https://ukdataservice.ac.uk/help/secure-lab/what-is-the-five-safes-framework/).

The Archimate files are managed in the [Architecture Repository](https://github.com/sa-tre/satre-archimate).

A report on the architecture is available on [zenodo](https://zenodo.org/records/10053383).
