It would be really great to summarise this really usefull knowledge in a
ref:* tag, dedicated to Germany.
Let's take advantage of the unity of this model and operator agnosticism
(it seems).

In general it is very useful to distinguish operator, but as I understand
you, all German operators use the same cabinets and the same codes on them ?

If mappers doesn't have the information, they don't use operator=* :)

In France it would be the same for medium-voltage power : all operators are
using the same devices and equipment.
But they are operating areas as large as cities or group of cities. By
knowing the area, you're knowing the operator. May it be the same with
telephone in Germany ?

That's it, thus the building shouldn't be tagged man_made=MDF but
man_made=CO, don't you agree ?

Or even DF. My point was that a cabinet not only contains DF but other
equipments and they must be considered when tagging such a cabinet.

Any other objections regarding the proposal ?
