An open-source reference framework for the implementation of type 3 Asset Administration Shells

Seamlessly integrating assets into distributed digital ecosystems based on Industry 4.0/5.0 demands measurable impact: lower engineering cost, interoperability and adaptability. SMIA (Self-configurable Manufacturing Industrial Agents) addresses this as an reference framework for implementing autonomous digital counterparts of assets, unifying industrial and software standards. Its dual-layer architecture combines machine-interpretable semantic modeling with distributed functional software, enhancing interoperability, flexibility, and autonomy. SMIA represents assets by executing domain-specific tasks and performing peer-to-peer communication through standardized interfaces. Following open scientific software principles, it integrates mature technologies and provides reproducible deployment artifacts (e.g., Docker), ensuring traceability and extensibility while reducing engineering effort and technological fragmentation. • SMIA is an open-source reference framework that automates AAS type 3 digitization. • It joins standardization efforts from industrial and software engineering fields. • It boosts interoperability, flexibility, and autonomy across heterogeneous systems. • Normalized Digital Twins are self-configured from semantically enriched AAS models. • Built on open scientific software engineering for modularity and extensibility.
