OLA-HD: A Long-term Archive System

OLA-HD is a mixture between an archive system and a repository. The input is a .zip file whose content is structured as BagIt. The zip content will be validated before any further actions take place. Data uploaded to the system will be stored in both tapes and hard drives. The separation rules are defined in the configuration file. In addition, each uploaded zip gets a persistent identifier (PID). This PID can be used for sharing, citing, and versioning purposes.

If you deploy your own instance, a Swagger documentation is available at /swagger-ui.html.

System overview

All requests go first to the Nginx proxy. Depending on the URL path, it will either forward the request to the back-end service, or serves static HTML files. As depicted in the image, there are four components: Nginx, back-end, front-end for normal user, and front-end for admin.
