DSpace

It is a Java‑based institutional repository system that stores, preserves, and provides durable access to a wide range of digital objects, including documents, images, audio and video files. The backend exposes a REST API together with standard machine interfaces such as OAI‑PMH and SWORD, while an Angular front‑end supplies a web UI for users to browse and manage content.

The platform is self‑hostable, free to use under a BSD‑3‑Clause license, and does not require a subscription. It runs on a servlet container (typically Tomcat) with a PostgreSQL database, and can be deployed for development or testing via provided Docker‑Compose scripts.

It is used by research libraries, academic institutions, non‑profits and commercial organizations to create institutional, subject‑based, dataset or media repositories. The software offers granular group‑based access control, multilingual support, and integration points for external services such as ORCID and OpenAIRE, and is maintained by an active community of users and developers.
