There was a problem hiding this comment. Typo: "calculates creates" There was a problem hiding this comment. does There was a problem hiding this comment. It is a set of ogc:geomLiterals in practice likely bound to a SPARQL variable like in other functions too. There was a problem hiding this comment. @situx I saw your answer in another issue that one geomLiteral can carry a collection. There was a problem hiding this comment. My comment is answered. But @mperry455 's comment not answered yet |
