@quatrain/okf

Open Knowledge Format (OKF) flat file storage adapter for the Quatrain Core framework.

Overview

The @quatrain/okf package provides a file-based persistence adapter (OKFBackendAdapter) that serializes Quatrain PersistedBaseObject entities into a structured flat file filesystem directory conforming to the OKF format.

This adapter is specifically designed to facilitate local-first, offline-first architectures by excluding relational databases and utilizing structured directory trees containing lightweight JSON files.

Features

• Decoupled Architecture: Pure filesystem storage format independent of underlying Git versioning or synchronization layers.
• Operator Auditing: Automatically stores the operator's email in the document's metadata block (meta.created_by) for full change traceability.
• Hierarchical Layouts:
  • Telemetry: Saved as telemetry/YYYY-MM-DD/{type}/{HHMMSS}-{millis}-{bassinId}.json
  • Other: Saved as {collection}/{uid}.json
