completeness

@UWashPrincipalCataloger: You changed expected completeness (P2429) from eventually complete (Q21873974) to always incomplete (Q21873886). Are there any concepts in the Biology Online Biology Dictionary that aren’t notable per WD:N and as such couldn’t be linked from Wikidata? --Emu (talk) 09:03, 9 May 2021 (UTC)

@Emu: There are some entries that are just cross-reference to another term, and I don't think we'd want to include links to those. Also I just assumed that it was unlikely that every term would have an item, but if the idea is that they could, then I have misunderstood what eventually complete means.

@UWashPrincipalCataloger: The cross-references would probably mean that always incomplete (Q21873886) is more accurate. I agree that eventually complete (Q21873974) is ambiguous to say the least – if I understand it correctly, it’s somewhat linked to Wikidata property for an identifier that suggests notability (Q62589316), but I could be wrong. --Emu (talk) 18:07, 9 May 2021 (UTC)
