Editorial comments on R2RML

None of these are major:

Section 7.3

The example refers to the IRI-safe template value using the following:

[] rr:subjectMap [ rr:template "http://data.example.com/site/{LOC}" ].

the IRI-safe version kicks in only if the term is declared to be an IRI. I know that this is defined, later, to be the default case for subject map using a template but it may be worth making this clear in the text (or simply add the extra rr:termType to the example.)

-----
Section 7.6, first sentence

langauge -> language

----
Section 9.1 
(I am not sure the remark should go to this section, though)

I would expect that if I have:

[] rr:subjectMap [ rr:termType rr:BlankNode ] ;

in a triple map, what this means is that each row has a newly generated blank node as a subject. I wonder whether it is worth making this fact explicit in the document, it may not be entirely obvious.

----
Appendix:

The previous version of the document had a number of examples that were very helpful. It is a pity to throw them away. Either we should plan for a separate primer document (but I am not sure we will have the energy for that) or we should put those back into the spec document as an (obviously informal) appendix.

Cheers
