AAS Thing Python SDK

Welcome to the Asset Administration Shell (AAS) Thing Python SDK documentation. The AAS Thing Python SDK provides a toolkit for building Python-based Things that comply with AAS specifications.

As defined by the standard, an AAS acts as the digital twin of an asset, enabling seamless interoperability. The toolkit provides the necessary means to create AAS-based things integrated into the Smart Systems Service Infrastructure (S³I).

See the whitepaper for details:
