Practical, production-grade patterns for synchronizing catalog, holdings, and circulation data between legacy MARC21 sources, BIBFRAME-aware discovery layers, and modern ILS REST APIs — without compromising on FERPA, GDPR, or state-level patron privacy mandates.
Written for library technology staff, ILS administrators, and the Python automation engineers who keep catalogs flowing. Every workflow favors deterministic, idempotent, and auditable pipelines over clever abstractions: real handling of legacy exports, batch reconciliation, audit logging, and stage-specific validation gates.
Three tightly-scoped pillars cover the production realities of running modern catalog and circulation infrastructure. Each section opens with an architectural overview and drills into deployable Python implementations, schema enforcement strategies, and compliance-aware operational controls.
Domain isolation, MARC21/BIBFRAME interoperability, idempotent sync patterns, and privacy-by-design at the data pipeline level.
Streaming MARC parsers, async batch processing, REST polling with backoff, and schema-validated pipelines for production ILS integrations.
Zero-trust patron pipelines: identity resolution, PII masking, FERPA-aligned routing, retention enforcement, and audit-ready logging.
