Definition

The Entity State Construction (ESC) component:

  • Consumes structured evidential data produced by upstream ESD components.
  • Produces a User Entity State instance conforming to the MMC Entity State data type.
  • Performs evidence‑based construction, not interpretation.
  • Applies normative constraints on which Entity State elements may be populated.

Functional Requirements

Evidence Aggregation Collects evidential inputs produced by MIH, LPE, and BEE.
Consistency Resolution Resolves conflicts and redundancies between evidential elements using priority and confidence metadata.
Scoped State Construction Populates only those Entity State components that are supported by observable evidence and allowed by directives.
Attribute Binding Binds constructed Entity State elements to a specific logical entity.
Temporal Coherence Ensures temporal consistency of the constructed Entity State.
Governance Compliance Enforces constraints issued by A‑User Control policies and directives.
Provenance Preservation Attaches Data Exchange Metadata to the constructed Entity State.
Output Normalisation Produces a valid MMC EntityState instance for downstream AIM consumption.
