Do you prefer the Key to change to "ref:GNS"?
but GNS:id is used with most GNS imports.

GNS:dsg_code is the code of the feature and GNS:dsg_name is the name of the feature. Most of codes are hard to understand but the name is clearer.

At least one of (GNS:dsg_code and GNS:dsg_name) must  be included for 
reasons:

1- To easy revise and fix the import if there are import tag error.

2- Some GNS features currently has not exact OSM Equivalent some one may 
get more feature describe on "GNS:dsg_name" tag. In the future OSM may 
have more  Equivalent feature so this can be helpful.

This is summary of GNS features:

"Administrative Boundary Features"       20
"Hydrographic Features"                        137
"Area Features"                                        47
"Populated Place Features"                    15
"Road / Railroad Features"                    24
"Spot Features"                                    251
"Hypsographic Features "                    96
"Undersea Features"                            72
"Vegetation Features"                        18

there are some diffirent GNS features has one OSM Equivalent but with 
"GNS:dsg_name" user have more information about the feature.

3- If some OSM features added after the importing make more equivalence 
to GNS feature, these tag make changing to the new feature easier.
