The HLL Forum is the community for us who use the formal specification language HLL, and believe it is a good language for formal methods.

As it has started to become a de facto standard, we want to make sure that the language develops in a controlled way to meet the demands of the future.

The HLL Forum was formed in a first meeting in Paris on December 4th 2018. Since then, tool providers have been working together to merge their different dialects of HLL into one uniform language that we aim eventually to publish as the official next version of HLL. Equally important are the members using HLL and the tools in the market, such as signaling suppliers, infra structure managers and engineering firms. Users and providers working together to create safe and cost efficient rail control systems.

By joining the community you ensure that your voice is heard.
