Wikidata

Wikidata here is short for the community, not just the database itself, but also involves all the tools around it, such as Scholia.

Wikidata is a node in the Linked Open Data cloud. It has a rich model of statements, which are not unlike nanopublications. A key interoperability layer is the RDF export, allowing SPARQL queries. The data is licenced/waived under CCZero, and trivial to integrate. It already is has a lot of information about SARS-CoV-2 and COVID-19.
