Technical overview

We publish climbing content ("data") in two forms, human-readable and machine-readable. Having two representations of the same data enables us to address multiple community needs.

Benefits of a climbing route wiki:

We're hoping by creating a useful and easy-to-use wiki with a powerful "search engine" that provides value to our users, we can build a community of editors that will help us identify inaccuracies and improve the underlying data.

Benefits of open access to machine-readable climbing data:

  • Enable independent developers to build on and enrich the existing ecosystem.
  • Provide data science students with much needed datasets.
  • Increase the efficiency of public research related to climbing.
