**Data storage:** The Data Architecture Diagram also describes the virtual infrastructure ([data storage](https://gitea.geologie.ac.at/geolba/tethys.backend/wiki/DataArchitectureDiagram#3-storage-infrastructure)) used to store the data and metadata in the repository. By using PostgreSQL, TETHYS is able to manage large volumes of metadata and provide fast and secure access to this information. The data files are stored on an Ubuntu 22.04 file server with ext4 partition. Corresponding file checksums md5 and sha512 are also stored in the database.
**Data Discovery:** TETHYS supports data discovery in various ways. The datasets can always be found through the Data Frontend, https://tethys.at/search, browsing by subject, author, language or year, or by searching inside the metadata attributes title, author or keywords. All visible metadata are indexed and searchable by [Solr](https://tethys.at/solr/rdr_data/select). Tethys Metadata and File downloads can be queried by a REST API (Representational State Transfer Application Programming Interface), which allows repository staff to interact with the Tethys system and retrieve metadata and data files programmatically.

For the **metadata management** the Data Architecture Diagram provides information on the specific types of metadata that should be included with the data. This may include information on the format and structure of the metadata, as well as the types of information that should be included. Tethys RDR supports three metadata standards for the metadata export (**Dublin Core, DataCite and ISO19139**).
