CollectBinaryToNary

Revision as of 22:24, 2 March 2007

Lets assume you have imported an RDF file to Wandora. RDF supports only binary relations. However RDF allows you to pack multiple binary relations into a single entity that resembles n-ary association of topic maps. The trick is to use an intermediator between. BinaryAssociationTopicBreaker tool breaks n binary associations into a single n-association. Number of association topics is reduced by one as the intermediator is not necessary any more.

           c
          /
  (a -- b) -- d      ==>     a -- c -- d -- f   ,   [b]
          \
           f


           c
          /
  (a) -- b -- d      ==>     a -- c -- d -- f   ,   [b]
          \
           f

  x  = topic
 [x] = topic x is removed
 (x) = topic x is in context
 (x -- y) = association is in context
