masterfiler

Masterfiler is a term used in information management to describe a centralized system responsible for storing, organizing, and maintaining master copies of digital assets and their metadata. It functions as the authoritative repository from which derivatives, backups, and archives are generated, ensuring data integrity and traceability across an organization.

Core features typically include versioning and provenance tracking, a structured metadata model, access control and authentication, data replication and disaster recovery, deduplication for storage efficiency, auditing and tamper-evident logging, and search and discovery capabilities. A masterfiler may integrate with workflows, asset management systems, and backup solutions to support lifecycle management.

Architecturally, a masterfiler comprises a metadata store (such as a database or search index), a storage layer for the actual file data, a policy engine for retention and tiering, APIs and a user interface for ingestion and retrieval, and connectors to archival systems and external applications.

Typical operations include ingesting master copies, validating checksums and metadata, normalizing metadata, indexing for search, applying retention and lifecycle policies, replicating copies to remote sites, and retrieving assets for use or disposal. Change history and lineage are tracked to preserve provenance.

Use cases span media production and post-production, scientific data management, enterprise content and records management, legal eDiscovery, and government or institutional archives.

Origin and terminology: The term masterfiler describes a class of solutions rather than a single product, and may be implemented as standalone software, a feature of digital asset management (DAM) or enterprise content management (ECM) systems, or as part of backup and archiving platforms.
