Dear Sir, I thank you for your answer. The reference explains how such a situation is in part accurate. However, this is not the only situation where the use of instance of and subclass of is problematic. Please refer to https://dl.acm.org/citation.cfm?id=2891117 for such matters.

- Concerning the problematic use of Instance of and SubClass of, I invite you to see https://tinyurl.com/y29lx9o4. This seems to be not accurate as drugs differ from drug classes from a pharmacological view. For example, Artemisinin, Ibuprofen and Sobosbuvir are drugs. However, drug classes should include antibiotics and antivirals. Concerning WikiProject Ontology, I know it. The project succeeded to solve many matters related to the structure of Wikidata. However, the project is slow.
To me this is actually a nice example of *why* we need to distinction.
Sobosbuvir as in instance is often the active ingredient. Sobosbuvir as a class is often the formulation, which is not a single entity, but a class of formulations with different amounts (and concentrations) of active ingredient
It's just that in street/common language (not wrong, just different!) we don't use different words for it. Instance-vs-subclass are tools that help us make this distinction.
Now, related to this, plz have a look at https://www.wikidata.org/wiki/Wikidata:WikiProject_Chemistry where class and instance are both used, for good reasons.

-- Hi, do you like citation networks? Already 51% of all citations are available available for innovative new uses. Join me in asking the American Chemical Society to join the Initiative for Open Citations too. SpringerNature, the RSC and many others already did.
