PIQ is the Java incarnation of Parka's graphical query mechanism. There is a nice Lisp implementation and also a C version. Parka was originally a semantic network and later became n-ary, partially in response to SHOE's needs. You are correct, SHOE started out as a binary relation language and later evolved to n-ary relations. As a graphical interface, I think PIQ would present a very good model for RDF. Sean
