RODA is a long-term digital repository for ingesting, managing, preserving and providing access to digital content. Its functions cover the main units of the OAIS reference model. Ingest workflows validate submission packages, scan for viruses, identify formats and extract technical metadata; they can also migrate files to more preservable formats. Users can search and browse a catalogue using descriptive metadata and text extracted from documents. Repository managers can manage representation information and risks, define retention and disposal policies, and run preservation actions including format conversion, checksum verification and virus checks. RODA records PREMIS metadata for object actions, monitors integrity and logs human and software interactions. It supports OAIS, METS, EAD, Dublin Core, PREMIS and E-ARK Information Package specifications, and exposes functionality through a REST API. Integration options include filesystem packaging, relational database extraction with DBPTK, APIs and drop folders. The site describes its services as scalable across multiple servers and suitable for organizations with millions of digital objects. Community Edition is free at free and is intended for mid-sized organizations; commercial plugins, integrations and professional support are excluded.
