96    Ted Nelson's original
97    hyperstructure and applitude concepts
98    were developed for the ZigZag(tm) structure.

108    
109    RDF and ZigZag(tm) structure are actually closely
110    related: ZigZag(tm) is obtained if a RDF graph is constrained
111    by two uniqueness conditions: for all x, y, there can be
112    at most one triple of the form (x, y, *),  and
113    at most one triple of the form (*, x, y).
114    
115    While the ZigZag(tm) structure is simpler to browse locally,
116    programming is more difficult since representing one-to-many
117    and many-to-many relations is, while possible, laborious.
