schedulesnaps

Schedulesnaps are archival representations of a schedule at a specific moment. Each schedulesnap captures the state of the schedule, including tasks or events, assignments, time slots, dependencies, and metadata such as the user who created the snap and the timestamp.

They function as versioned snapshots that enable comparison across versions, audit trails, and recovery to a prior state.

Contents and formats: A typical schedulesnap carries a unique id, a timestamp, a reference to the parent schedule, and the complete or differential schedule data, often encoded as JSON, XML, or a compact delta. Some systems store only deltas between snaps to reduce storage.

Operations and use: Users can diff two snaps to see what changed, revert a schedule to a previous snap, or branch a schedule for scenario planning. Schedulesnaps can be exported for reporting or imported back into the scheduling system.

Implementation approaches: Snapshots may be full copies stored as separate records, or incremental diffs applied on top of a base version. They can be persisted in relational databases, document stores, or within version-control style archives. APIs may expose create, list, diff, restore, and compare endpoints.

Applications: In project management, workforce scheduling, event coordination, or production planning, schedulesnaps support accountability, audits, and what-if analysis by preserving the history of changes.

Considerations: Storage overhead, data privacy, consistency with concurrent updates, and retention policies should be addressed. Clear naming and provenance help users understand the origin and intent of each snap.
