Perhaps because of the above, a subject like this:

<https://.../resource/degree/urlify(education_degree)!subj>
        a            rr:SubjectMap ;
        rr:class     :AcademicDegree ;
        rr:template  "https://.../resource/degree/urlify{education_degree}" .

causes an unchanged URL https://.../resource/degree/urlify{education_degree} to be emitted (no template substitution).

Furthermore, { is an invalid URL char, it needs to be escaped.

I fixed the problem. Please test it out.

I just notice that a parameter was missing in the string substitution call. I just fixed it.
