Re: ISSUE-37, ACTION-138: DBMS connection details in R2RML mappings

Kingsley, why do we need to say anything about DB Connection in the R2RML Standard?
The standard is about mapping.  You connect in any way that works for you and, as you know,
there is a lot of variation in how you connect from vendor to vendor.
Why do we want to go there?

My unstated goal in putting this issue on the agenda was the hope that
we could close it quickly without action :-)
All the best, Ashok
