Distinct values for a cancer vs a neoplasm?[edit]

For many different types of cancer, both the cancer and the neoplasm are referring to a single MeshID. See neck cancer and neck neoplasm for example.

Yes, it's a serious issue. Many of the cases are introduced by bot edits, and I have had discussions on the topic. Charles Matthews (talk) 09:54, 8 September 2019 (UTC)

Allowable constraint violations[edit]

As far as I know, there are two cases where the constraints should, arguably, be ignored.

One is for the "single value" constraint. As on periodical (Q1002697), there is an artefact of the MeSH system meaning there are different identifiers for Periodical [Publication Type] and Periodicals as Topic. On PubMed, these are used in different sections of the MeSH term listing. But really there is no difference as object of a Wikidata statement.

The other is for the "distinct value" constraint. While the scope notes for a MeSH term are normally carefully drafted, they do not always allow one to read off the intended taxon range, which can be humans, primates, mammals or vertebrates, or all organisms. For instance, for lung the MeSH page does not give enough to decide between human lung (Q2640512) and lung (Q7886) which covers animals. Charles Matthews (talk) 10:05, 8 September 2019 (UTC)

shows item with more than one P486 statement. At the time of posting there were 44, that seemed admissible. The number can vary. Charles Matthews (talk) 11:16, 30 September 2019 (UTC)
