To store and handle the KG, we decided to start with the free version of GraphDB . The primary reason for this choice being the ease for novice users to install it on their working station. To populate the KG and manage its content with respect to many data sources, we developed a command line tool called kgsteward that relies on a configuration file, currently in YAML format. This configuration file is shared through Git and permits the different users to host their own local instance of the triplestore, allowing each one to improve the schema/data at their own pace. This decentralized working approach was possible so far, as the KG remains relatively modest in size (~200 millions of triples). Additionally, kgsteward proficiently utilizes SPARQL updates to amend RDF imported from external sources and also features tools for quality control. A comprehensive DMP is required for the project. To facilitate its compilation, summaries including collections of samples, analysis runs and their metadata and number of measurements are retrieved via SPARQL queries from a Rmd script. The generated html report is put on the project website, and also provides an entry point for data retrieval. Dedicated graphical interfaces are being developed using visNetwork .
