We generalize the notion of Lagrangian subspaces to self‐orthogonal subspaces with respect to a (skew‐) symmetric form, thus characterizing (skew‐)self‐adjoint and unitary operators by means of self‐orthogonal subspaces. By orthogonality preserving mappings, these characterizations can be transferred to abstract boundary value spaces of (skew‐)symmetric operators. Introducing the notion of boundary systems we then present a unified treatment of different versions of boundary triples and related concepts treated in the literature. The application of the abstract results yields a description of all (skew‐)self‐adjoint realizations of Laplace and first derivative operators on graphs.
