Abstract
Databases are one of the most important resources for researchers in data-driven domains. In many organizations, it is yet still a challenge to make databases available from the beginning of a project and databases are maintained by some IT-savvy researcher who has the burden to do these tasks on-top of (or rather before being able to do) research. We present a repository for relational databases in a private cloud-based setting that: i) enables research early by providing databases on demand for researchers; ii) enables separation of concerns into researchers who work with the data, data providers who feed data into databases, IT-professionals who maintain the databases and the infrastructure and data stewards who curate data in databases; iii) allows assignment of semantic information of the table schema, by storing concepts from the Wikidata knowledge graph and units from the Ontology of Units of Measure; and iv) allows precise and persistent identification databases and arbitrary subsets.
