Objective

Enables Local Digital Twins (LDTs) to orchestrate workflows, data, models and visualisations across systems, domains, and communities. It ensures that LDTs move beyond isolated, project-specific implementations toward federated, reusable, and scalable ecosystems, ensuring:

• Cross-domain decision support (e.g. climate, mobility, urban planning)
• Reuse of models, datasets, and simulation outputs across communities and use cases
• Participation of multiple stakeholders (public, private, citizens)
• Progressive maturity from standalone LDTs to interconnected virtual worlds environments (note, virtual worlds environments is not addressed by MIM8.)

In doing so, this MIM leverages on all MIMs (0,1,2,6,3,4,7,5) and provides guidance for interoperable orchestration measures.

MIM8's scope re orchestration:

MIM8 (LDT) positions orchestration as the capability to connect and coordinate LDT components (add capability instead of components) within an LDT (intra-LDT) and between LDTs (inter-LDT), progressively across maturity levels. Intra-LDT orchestration focuses on interoperability across architectural layers, most critically enabling the same scenario outputs to be consumed by different visualisations (e.g., Geo and 3D) and allowing different predictive/algorithmic models to be plugged in with clearly specified inputs, parameters, and outputs, including automated checks for schema/unit/space-time alignment. Inter-LDT orchestration covers controlled exchange and reuse of data/models/scenario results with other LDTs via standard interfaces, with governance hooks such as access control, provenance, and audit logging.
