We present an information resource prototype that was developed by the FREYA project for the integration of a national e-thesis service and institutional repositories supported by a large national laboratory. The integration allows us to mutually enrich the metadata in the e-thesis service and institutional repositories with new entities and attributes, and can offer novel ways of reasoning over research outcomes that are supported by direct funding and funding-in-kind by large research facilities. The integrated information resource can be presented as a labeled-property graph for its exploration with a declarative query language and visualizations. We emphasize the role of persistent identifiers (PIDs), including for entities that are currently not necessarily or not consistently assigned PIDs.
