When looking for hiking trails I noticed that I always had to search through 1000 pages to find the little information I need: Overview, accommodations and Gpx data. It made sense to collect relevant links. So that it might be useful to others, I have programmed it as a web service. Anyone who wants to use the WSDL is welcome to write to me at tilo.rabs@streckenweise.de. The only catch thing: it needs to be updated constantly, I can't always manage that.
