[Tagging] Names on relations and not component ways

[dies38061 at mypacks.net]

"...why do you duplicate the tag waterway=river on every way...."

Because the relation can contain more than simply the waterway.  For instance, one could add the riverbank, islets, and slips if one were so inclined.  By letting each component way retain an identity of what it is, the relation grouping takes on the purpose of telling what it's called, "it" being the variety of component types which make up the thing called "Tappahanna Ditch".  I just haven't added any of the extra things (chief being the riverbank) to the relation (and likely never will). --ceyockey
