The hiking route networks (regional + national) does not appear up-to-date.
I have experienced discrepancies between what is shown on ut.no / dnt.no compared to what is shown in OSM and the website tag is invalid(eg. Relation: RYF8 (5573078) | OpenStreetMap referes to a route with reference RYF8 with the (invalid) website pointing to http://www2.turistforeningen.no/trail.php?tr_code=ryf8)
Does the RYF8 reference have any meaning anymore and do we have newer data we can use?
Example from Waymarked Trails below
