All,
Stumbled upon another COVID-19 dataset and SPARQL endpoint published to
the LOD Cloud Knowledge Graph [1][2]. This time around, it's from the
CoronaWhy Project [3].
Naturally, we've loaded this dataset to the LOD Cloud Cache instance
that we maintain which is also accessible via a SPARQL endpoint [4].
Here's some sample SPARQL query results pages from both instances:
[1] LOD Cloud Cache
