Thank you for your comment. The second argument of the P125 is the type of things used in an activity. Still the type of an object is not equal to the way such an object is used in an activity. Trilobite fossils can be used in the production of a jewellery as a mold. (My daughter has one in gilded silver).
This is an argument for a P125.1 mode of use. The technicalities: P16(x,z,w) is the current notation for P16.1(x,z,w) (1) for all w P16(x,z,w) ⇒ P16(x,z) and we already have declared the axiom (2) P125(x,y) ⇔ (∃z) [E70(z) ∧ P16(x,z) ∧ P2(z,y)] and (3) below can be deduced from (1) and (2): (3) P125(x,y) ⇐ (∃z) [E70(z) ∧ P16(x,z,w) ∧ P2(z,y)] The other way is not so easy since (5) below cannot be deduced from (2) since the fact that a specific thing is used in an activity does not imply that this thing is used in the mode of used described by any instance of E55 Type which would have been the case if (4) were universally true. (4)P16(x,z) ⇒ P16(x,z,y) (5) P125(x,y) ⇒ (∃z) [E70(z) ∧ P16(x,z,y) ∧ P2(z,y)] So we need to add (6) P125(x,y,w) ⇒ (∃z) [E70(z) ∧ P16(x,z,w) ∧ P2(z,y)] That is, if an activity x, uses things of type y in the mode of w then there exists a thing used in x in the mode of w and the type of x is y. But now we need to take into consideration that the short path has a .1-property and we add P125(x,y,w) ⇐ (∃z) [E70(z) ∧ P16(x,z,w) ∧ P2(z,y)] I hope this is correct.

If P125, nothing tells us that the unknown z is the same as one possibly in a full path of the same activity. Nothing tells us why there should not be more than one "w" for the same z. Is that what you mean? I'd support creating such a P125.1. Best, Martin On 11/30/2022 3:57 PM, Christian-Emil Smith Ore via Crm-sig wrote: B: Typo: P125 should be P125.1 in the bold phrase.

Simply, similar examples have not been provided. I suggest a FOL for that. "P138.1 mode of representation seems to be unrelated to P62.1 mode of depiction. Conclusion Neither of the .1-properties in the long path are semantically related to the .1-property of the shortcut property. Since P62 is declared as a shortcut of the long path, it cannot have the .1-property." I agree that P67.1 is unrelated. The kind of reference of a P138 instance would be "represents". This is implicit I think in the explanation of .1 properties of "has type"-type in the introduction. Could be a new issue. B) "The implication from the long path to the shortcut is ok since the shortcut has no .1-property. The implication from the shortcut to the long path is problematic since there is a .1-property in the long path.

E.g., used "passiflora racemosa flower", mode of use "as model", (Martin Johnson Heade, "Hummingbirds and Passionflowers", ca 1870-1883, Museum of Fine Arts Boston, https://artsandculture.google.com/asset/hummingbird-and-passionflowers/LAEr7eIcfErZwg?hl=en-GB&ms=%7B%22x%22%3A0.5%2C%22y%22%3A0.5%2C%22z%22%3A8.643661874326806%2C%22size%22%3A%7B%22width%22%3A3.2807205935359844%2C%22height%22%3A1.2375%7D%7D) a typical case for the ten thousands of botanical images from European botanical researchers in the previous centuries. Funny example is John James Audubon: He reportedly shot a bird in 1812 in Pennsylvania, named it "Regulus cuvieri", painted it probably with an error in "Birds of America", so that this species was never seen again.
