Data Structures

voiage uses a small set of explicit data structures to keep method inputs and outputs serializable, inspectable, and stable across bindings.

Core contract

The core contract treats xarray Datasets as the canonical in-memory representation for public data structures. Helper constructors and copy methods preserve dataset coordinates so bindings can round-trip the same labels without flattening them into tabular objects.

Key structures

• ValueArray — net benefit array with structured round-trip helpers (from_dataset() / to_dataset())
• DecisionAnalysis — analysis orchestration facade
• Intervention — intervention definition
• DecisionProblem — decision problem formulation
• TrialDesign — trial design specification
• ParameterSet — parameter set with round-trip helpers (from_dataset() / to_dataset())
