Lets assume you have imported RDF 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 association with n players. Number of association topics is reduced by one as the intermediator is not necessary any more. Examples:
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 = binary association between x and y
x - y - z - k = 4-ary association between x, y, z, and k
(x -- y) = association is in context
The tool is very useful to clean up not only RDF triplets but also CIDOC CRM data.
