One of the main challenges of this enterprise is the management, integration and sharing of the highly heterogeneous data that are produced by the different research groups. Additionally, requirements for the data management plan (DMP) and open-source science with the FAIR principles (findable, accessible, interoperable, reusable) must be met. We decided to use Resource Description Framework (RDF) and SPARQL to progressively assemble a knowledge graph (KG) containing relevant data and metadata produced by all collaborators. This paper summarizes our experiences in this still ongoing project.
