to be complete, we are missing a " or ... "
since the design is very open to new kind of mapping ...
We could imagine a mapping based on the geo localisation, or the user agent ...

"resource" was the most common name I could find to name this ...
and this is not related to the "web resource" .. as we often design a REST resource ... in CRUD design or similar

if someone has a better name for this .. I am open to suggestion
