Subject: don't URL-encode rr:column
http://www.w3.org/TR/r2rml/#from-template says: "R2RML always performs percent-encoding when IRIs are generated from string templates. If IRIs need to be generated without percent-encoding, then rr:column should be used instead of rr:template". However, rr:column us turned into rr:template (by surrounding it with {..}), so this distinction is lost. - This is done 4 times in R2RML.pm, search for {%s}. One of them sets _about_is_column, but only for Subjects. - in Simple.pm, template() and template_irisafe() should be called only for rr:template but not for rr:column. I attach a test. It should output http://purl.org/dc/elements/1.1/title or dc:title but not http://example.com/base/http%3A%2F%2Fpurl.org%2Fdc%2Felements%2F1.1%2Ftitle
