Aspects are documented as being Endurants, which they are not #13

Describe the bug In the documentation, Aspects are considered Endurants. At the same time, the individuals they instantiate are considered to inhereIn ConcreteIndividuals. The latter I concur, but the former is very confusing - at least for me. Particularly, according to the Taxonomy of Individuals gufo considers Qualitys to be Aspects . However, according to the ontological sextet below (adapted from [1]; part (a) adapted from [2]) Aspects (*) stand on themselves and characterise Endurants.

OntoSquareAndSextet

(*) Depicted above, in Figure (a), the Aspects are denoted in [1] as Quality Universals and in [2] as Moment Universals; I assume that these are more denotational differences whereas their meaning are equivalent over [1], [2] and gufo. If not, this could be the source of my confusion.

Expected behavior I assume that in the Taxonomy of Individuals, one should consider Aspects at the same level as Endurants, Events and - possibly - Situations.

If I'm wrong in my conclusions, than I suggest to improve the documentation -- not being able to understand a text is considered a flaw of the text as opposed to an incapability of the reader 😉

This appears related to #11 .

Paul, you seem to be conflating endurants and substantials.

UFO partitions endurants into substantials and moments. gUFO partitions endurants into objects and aspects (with change in terminology, and a slight change in coverage. See http://purl.org/nemo/doc/gufo#Object for how gufo:Object relates to UFO notions.)

So, in sum: Aspects are not objects. But they are endurants (continuants in BFO terminology).

Ah João, thank you, I stand corrected. Indeed I did conflate those, what a rookie mistake :-)

I should understand an endurant as "Something endures if and only if it persists by being wholly present at different times", with its distinction between Objects (substantials) and Aspects as without and with existential dependence on another endurant.

My picture above is wrong and had it corrected, removing the conflation of substantials with endurants.
