The faculty data infrastructure Digitalia MUNI ARTS is technically based on the Islandora system, which consists of several components:
Drupal is used to manage the repository content, store metadata and provide a friendly user interface.
The files themselves are stored in Fedora. Fedora services include versioning and fixity checking.
Apache Solr is used for indexing content and searching the repository.
Islandora microservices provide synchronization of Drupal and Fedora content and integration of various image, video, and text processing applications.
A more detailed diagram of Islandora’s architecture is included in its documentation.

The system uses the infrastructure for running virtual servers at Masaryk University built on VMware technology located at the MU Institute of Computer Science. The operating system is Ubuntu LTS (as recommended by Islandora Community).
Backups are performed regularly to a tape device on Bacula system managed at the MU Institute of Computer Science.
Changes in metadata of all record types are recorded in Drupal. Users with the Content editor role can view, compare, delete, or revert to a previous version of objects (called Revisions).
Content of databases is accessible to non-logged-in users as well. Such a user can browse individual records and files, apply filters and use search.
Logged in users with the Content editor role have access to record edit forms. They can also manage versions of objects (see Servers, backups, integrity and authenticity).
The content of the repository is accessible via the REST API. The supported formats for the GET method are csv, json and jsonld.
The Matomo tool is deployed to track the usage of the site. The collected data is stored on a local server.
