    The debate is not only about hierarchies. Hierarchies are just one kind of
    associations in the Topic Maps paradigm.
    Topic Maps are indeed the tool to escape the
    verticality/hierarchical/classification paradigm in knowledge
    representation !
    What you call "lateral location" is tackled by the association concept,
    allowing multi-dimensional representation of the "semantic neighborhood" of
    a subject.
    You have all the needed technology in XTM specification
    Mondeca software is allowing various topic-centered
    representations and navigation, based on both TM topological graphs
