A common construct in turtle files is the following: ex:fooInstance ex:predicate ex:barInstance . In other words, three qnames followed by a period, denoting a statement. A problem arises if any of the qnames contains a period, like this: ex:foo.instance ex:pred.i.cate ex:bar.instance . In this case, the first period is interpreted as a statement terminator, resulting in a parsing error. Looking into the turtle grammar at [1], I found much to my surprise that a period is not allowed in such identifiers in turtle. In contrast, the period is allowed in XML -- see the NameStartChar and NameChar productions at [2] and [3]. It is likewise allowed in RDF. This seems like a serious limitation of turtle. Am I missing something? Thanks, Ian [1] http://www.dajobe.org/2004/01/turtle/#sec-grammar-grammar [2] http://www.w3.org/TR/REC-xml/#NT-NameStartChar [3] http://www.w3.org/TR/xml11/#NT-NameStartChar
