Category:Symmetric relation
From semanticweb.org
A binary relation R over a set X is symmetric if it holds for all A and B in X that if A is related to B then B is related to A.
In mathematical notation, this is:
In SMW we have to distinguish between semantic symmetry and actual symmetry, i.e., symmetry in the sense that whenever A R B is annotated, also B R A is annotated. The latter implies also that page B exists, hence, that we do not annotate a relation to a non-existing page..
