Bug with SERVICE directive about cliopatria HOT 3 CLOSED

I think it is a bug. I was experiencing similar problems. Jan, Wouter: I do not understand how the explicit mixing of rdf_db and rdf11 literals in ClioPatria/rdfql/sparql_runtime.pl is intended to work. This module first imports rdf_db and then :- use_module(library(semweb/rdf11), [rdf_lexical_form/2]). This looks like the use of the new rdf11:rdf_lexical_form in "old" rdf_db code in the example above is intentional, e.g. in binding_line(Name=Literal, Line) :- rdf_lexical_form(Literal, Lex), % THIS LINE expects Literal to be in the new "Frida Kahlo"@en format and throws the exception on the old literal(lang(en,'Frida Kahlo')) ( Lex = ^^(String,Type) -> format(string(Line), 'BIND(~w^^<~w> as ?~w)', [String, Type, Name]) ; Lex = @(String,Lang) -> format(string(Line), 'BIND(~w@~w as ?~w)', [String, Lang, Name]) ). Jan, is this the same "should we have a general solution to handle literals when mixing old rdf_db and new rdf11" discussion we had last week? Thanks, Jacco
