I've been looking again at Shape Expressions and have come up with some
cases that may not be defined well.
Consider the following simple RDF graph
@prefix ex: <http://ex.com/> .
ex:a ex:p ex:b .
ex:b ex:p ex:a .
and the following simple shape expressions
PREFIX ex: <http://ex.com/>
<R> { ex:p @<R> }
<S> { ( ex:p @<S> | ex:p @<T> ) }
<T> { ( ex:p @<S> | ex:p @<T> ) }
What are the results of rule evaluation
1/ as they should be,
2/ according to Shape Expressions 1.0 Definition,
3/ according to other definitions for Shape Expressions,
and
4/ from implementations?
