Welcome to the Website of CAAML


CAAML (Canadian Avalanche Association Markup Language) is a standard for the electronic representation of information pertinent to avalanche safety operations. By building on existing Internet standards, CAAML expresses avalanche related information in a manner that can easily be shared over the World Wide Web. CAAML builds on the following two existing standards:


The purpose of CAAML is to provide the definitions for the data file structure to support electronic exchange of avalanche related information. CAAML defines the structure and elements of observations types, specifies how locations are referenced, provides a mechanism for linking observations with each other and contains a method for associating external data files.
