i have two geojson files which include the borders of “oberwallis” and “unterwallis”. how would i contribute these borders to openstreetmap? is there a guide i can follow? is someone responsible for this region? can i send these geojson files to someone?

While Ober- and Unterwallis are probably more a thing than 99.9% of other non-administrative boundaries, I don’t believe there is any formal definition that would lend itself to generating a hard boundary.
How did you create the files and what definition of the regions did you use? Depending on that we can decide how best to proceed.
i got the files from the geoportal of the canton valais. i asked them by email. they gave me two geojson files which contained the borders of all communes and i “merged” (forgot the correct word for this) the borders to only have the outer borders
i also asked about the license or if i am allowed to use the data to contribute (or give it to someone) to openstreetmap. they said yes
i am interested in adding this to openstreetmap cause i started a community in the canton valais in the german speaking region and there is a site that uses openstreetmap data to define the borders of a community. and at the moment my community is the whole canton of valais and not only the oberwallis

If the areas only contain complete municipalities then you just have to create two new boundary relations and click together the member ways, that is the ways in the cantonal boundary except for the municipalities along the Ober- Unterwallis border, and for those the corresponding ways of the municipality boundaries.
The simple way to do this is to: create a copy of the cantonal boundary relation, select and cut all the members that belong to the “other” region and use those to create a 2nd new relation.
Then add the missing members from the municipality boundaries to both of the relations (as these will be the same for both new relations, you just have to do this for one of them and then copy the members to the other relation).
That’s the easy, 10 minute work bit.
The other bit is deciding what kind of boundary relation these should be, this should be something that is supported by the OSM search engines but does not imply anything fake.
PS: in case this isn’t clear: if you haven’t edited OSM before, this is not the project to start with :-) You should be fluent with one of the editors that properly support relations (that is JOSM or Vespucci) and have a good knowledge of how boundaries work in OSM and experience editing them.
good you added this. i have no experience with this. and can’t take the time to get fluent with an editor. i will add the 4 files i have. maybe someone can tackle this
i can’t add the files here in the forum. i’ve created a public folder:
(Gemeindegrenzen_Oberwallis.json and Gemeindegrenzen_Unterwallis.json are the original files i got via email and oberwallis_border.json and unterwallis_border.json are the edited files by me, which only contain the borders of the two regions)
