We need to extract a small sample from CantusDB to try to upload that to Virtuoso directly

This issue follows DDMAL/linkedmusic-datalake#104. And it's closely related with DDMAL/linkedmusic-datalake#67

Over time, we have become uncertain that regarding CSV2RDF (LinkedMusic), whether using python (plus RDFLib package) is the best approach. As a result we begin trying an "RDF-specific" method using R2RML (RDB to RDF Mapping Language, compliant with W3C standards) in Virtuoso to achieve RDB2RDF & reconciliation.

The CantusDB as a whole is too large. I just need a very small sample with complete schema information. Ideally, this sample would include a few entries for each entity and each relation, sufficient for experimental purposes.
