Hi, While reading the last version of SPARQL, I am surprised with the following definition. I don't know if the semantics of RDF (and consequently SPARQL) is changed. Definition: Triple Pattern A triple pattern is member of the set: (RDF-T union V) x (I union V) x (RDF-T union V) >From the above definition, the literals are allowed in the subject position. However, they are not allowed in RDF. So, I want to know if it is a mistake or not? - For blanks in SPARQL, I want to know if they act as variables or not, that is, if a blank can be mapped to any RDF term (or just to a resource)? I need some explannation on that, because blanks = anonymous variables. What is a resource? Is it a literal or an IRI or just an IRI? - Is the case that blanks are not allowed in the predicate position? Best regards, Faisal Alkhateeb Ph.d. student, INRIA Rhône-Alpes
