imagerepository

An imagerepository (often written as image repository) is a software system designed to store, manage, and retrieve image files and their associated metadata at scale. It serves as a centralized catalog and storage layer for digital imagery across an organization, combining file storage with search, access control, and workflow features.

Key components include a storage backend (local filesystem or object storage), a metadata model and indexing engine, a user interface and APIs for ingestion and retrieval, and features such as versioning, rights management, and audit logging.

Image repositories typically support metadata standards such as EXIF, IPTC, XMP, and Dublin Core, enabling rich information about authorship, capture conditions, licenses, and provenance. They store or generate thumbnails and previews and may manage color profiles and metadata preservation during format conversions.

Ingestion and processing workflows handle importing, deduplication, normalization, tagging, and automated tasks like transcoding, watermarking, or generation of different sizes for delivery.

Repositories provide search and filtering based on metadata, keywords, dates, rights, and collections, and often expose RESTful or GraphQL APIs for integration with content management systems, digital asset management, catalogs, or web front ends. Access control enforces role-based permissions and can enforce licensing terms or usage restrictions.
