Describe the bug

URIs from http://identifiers.org/mesh namespace, such as http://identifiers.org/mesh/D014376
are missing http://www.w3.org/2000/01/rdf-schema#label in KG-COVID, although this information is available, for http://identifiers.org/mesh/D014376 the label is "Turbecolosis".

To Reproduce

grep "identifiers.org/mesh.*label" kg-covid.nt
