Digital Twin Command Orchestration with Dependency Schema

The patent segments the command execution model into distinct components: commands, dependencies, workflows, and states. Each aspect is separately defined in the extended DTDL schema, allowing command dependencies to be expressed as separate relationship entities rather than being embedded in the command definitions themselves. This segmentation enables the language to maintain its existing digital twin modeling capabilities while adding explicit dependency expression without conflating different conceptual layers.

The patent introduces an intermediary dependency model that mediates between commands and their execution order. Rather than directly embedding execution logic in command definitions, the dependency model acts as an intermediary layer that describes relationships between commands, workflows, and states. This intermediary structure preserves the declarative nature of DTDL while enabling complex orchestration scenarios through separate dependency declarations.

The patent implements universal relationship types (IsOrchestratedBy, DependsOn, PreCondition, PostCondition) that can be applied across different command scenarios. These relationship definitions serve multiple purposes: they define execution order, specify prerequisites, describe state transitions, and enable workflow composition. This multi-functionality reduces the need for separate language constructs for each orchestration scenario, managing complexity through reusability rather than proliferation of syntax.

The patent requires that command dependencies, workflows, and state transitions be declared in advance through the extended DTDL schema. This preliminary declaration approach allows the system to automatically generate execution plans and validate dependencies before runtime, rather than requiring complex runtime decision-making logic. The upfront structuring of relationships simplifies the execution engine's task while enabling sophisticated orchestration behavior.

The patent constructs workflow representations and execution plans in advance by processing the declared command dependencies and relationships. This preliminary workflow construction occurs during system initialization or model loading, allowing the execution engine to work with pre-compiled workflow graphs rather than interpreting dependency relationships in real-time. The upfront processing trades initial construction time for significantly faster runtime execution and validation.

The patent maintains continuous workflow execution by efficiently managing state transitions and command sequencing based on pre-established dependencies. Once workflows are constructed, the system continuously executes commands in the determined order without repeated parsing or analysis of dependency relationships. This continuous execution mode minimizes processing overhead during runtime while maintaining automation capabilities.
