From: Crm-sig <crm-sig-boun...@ics.forth.gr> On Behalf Of Christian-Emil Smith Ore via Crm-sig Sent: 28 October 2024 11:58 To: crm-sig@ics.forth.gr Subject: Re: [Crm-sig] About the relationship between symmetry and transitivity It is clear that having the same domain and range is not a sufficient condition for a property to be either symmetric or transitive as your example with P152 has parent (is parent of) clearly demonstrates. Also "Properties that have identical domain and range are either symmetric, asymmetric or neither." covers all cases and is a tautology. Maybe it is better to reformulate the paragraph to "Symmetric and transitive properties have identical domain and range. Instantiating a symmetric property implies that the same relation holds for both the domain-to-range and the range-to-domain directions. An example of this is E53 Place. P122 borders with: E53 Place. The names of symmetric properties have no parenthetical form, because reading in the range-to-domain direction is the same as the domain-to-range reading. Properties with identical domain and range that are not symmetric, such as E41 Appellation. P139 has alternative form (is alternative form of): E41 Appellation, have a parenthetical form that relates to the meaning of the inverse direction."
