This code is based on the RDF N-Quad parsing code that I wrote for the Cayley graph database project in 2014. The code here does not include any code that was written by other members of the Cayley project and so is unencumbered by copyright ownership from that project. License addition is for the test suite from [1] linked from [2]. A second more restrictive license is possible if we are claiming spec compliance[3].
