Replay and Reconstruction Role
Discussion
The Replay and Reconstruction Role identifies responsibility for reconstructing or replaying selected FX information from preserved records, provenance, audit records, and evidence-supporting material.
This role includes receiving replay or reconstruction requests, identifying source records, following lineage relationships, reconstructing selected information, producing FX Replay Results, and preserving replay or reconstruction provenance.
The Replay and Reconstruction Role participates primarily in the FX Logical Audit and Provenance Plane. It also supports the FX Logical Control Plane when replay uses control commands and the FX Logical Data Plane when reconstructed or replayed information enters a data-plane exchange.
Definition
responsible for reconstructing or replaying selected FX information from preserved records, provenance, audit records, and evidence-supporting material
Source
Specialization of Logical Node Role from 02-part, Section 6.4, Logical Information Lineage from 02-part, Section 8.10, Logical Evidence Traceability from 02-part, Section 12.8, and Traceability from 01-part, Section 7.10; generalised from replay, reconstruction, audit, provenance, and evidence material in the original FX Demo Reference Architecture.
Note
The Replay and Reconstruction Role does not prescribe a replay engine, event store, database, log replay mechanism, provenance store, evidence repository, or test tool.
Example
The FX Replay and Reconstruction Node performs the Replay and Reconstruction Role by reconstructing the lineage of an FX Release Package from preserved audit and provenance records.
