There is a Memorandum of Understanding (Q1053964) between Wikimedia Deutschland (Q8288) and Universität Erfurt (Q702524) about building a database — named FactGrid and to be hosted at Forschungszentrum Gotha der Universität Erfurt (Q1438165) — with a level of granularity that is driven by research needs (primarily of historians) rather than Wikidata:Notability. I am about to get involved and thus beginning to collect information on the project.
FactGrid will be seeded with content from The Gotha Illuminati Research Base, which is of historic interest.
FactGrid is aiming at licensing its content under CC BY 3.0 (Q14947546). I am not sure this is the way to go forward and recommend serious consideration to go for CC0 (Q6938433) instead to ensure maximal compatibility with Wikidata. There are other databases that have recently switched their licensing to CC0 for this reason, e.g. see the respective announcement by WikiPathways (Q7999828).
