Hi all
I've just read the whole thread of the direct mapping subject, and I
totally agree with Richard.
Also, as Alexander pointed out in his previous email "there are
advantages of being able to automatically generate a default R2RML
mapping from the RDB schema. However, this is procedural mechanism which
cannot be part of the specification of the R2RML (declarative) language.
We as a WG can publish a separate recommendation / standard of how to do
this".

I think the same as Richard.
We can include an appendix for describing the procedure of creating the
R2RML file for the direct graph generation.
