I’m curious as to why SPARQL disallows re-using the same blank node label in more that one BGP in a SPARQL query (https://www.w3.org/TR/2013/REC-sparql11-query-20130321/#grammarBNodes).
What would be the problem with a query like
prefix : <ex://>
select * {
{ ?s :p1 _:b0 . }
union
{ ?s :p2 _:b0 . }
}
thanks,
