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.

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. Egon -- 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. ----- E.L.
