Definition
AUF Status (PGM‑AFS) is the Status produced by A‑User Formation in response to an AUF Directive. Before rendering, it reports what A‑User Formation is about to render, the Text Object and the per‑channel Personal Status it will use, so that A‑User Control can inspect and, if it chooses, override it. After rendering, it reports the formation outcome, the per‑SubAIM outcome of each formation step with the reason for any failure, and the A‑User Storage operation outcomes. It is correlated to the directive it answers.
Functional Requirements
- Status Identification and Traceability: The status shall include a unique identifier (AUFStatusID) and a timestamp (AUFStatusTime) to ensure traceability.
- Directive Correlation: The status shall include the AUFDirectiveID of the AUF Directive to which it responds.
- Environment Identification: The status shall include identifiers for the M-Instance (MInstance) and U-Environment (UEnvironment) in which the status applies.
- Session Identification: The status shall include a SessionID identifying the A-User session to which the status belongs.
- Render State Reporting: The status shall report the current render state (pending, rendering, rendered, not_rendered).
- Pre-render Reporting: Before rendering, the status shall report what A‑User Formation is about to render: the Text Object and the per‑channel Personal Status it will use.
- Formation Outcome Reporting: After rendering, the status shall report the overall formation result and the state of the produced avatar.
- SubAIM Outcome Reporting: The status shall report, for each formation step (speech synthesis, face description, body description, avatar synthesis), the outcome and, where the step failed, the reason for the failure.
- A-User Storage Outcome Reporting: The status shall report the outcomes of the A-User Storage operations performed during formation.
- Data Exchange Metadata: The status shall include DataXMData to provide standardised metadata supporting interoperability, traceability, and data exchange control.
- Descriptive Metadata: The status may include DescrMetadata to provide additional human-readable context.
