The forum was an exciting opportunity to learn how HLL is used today, and to discuss how HLL can evolve in a controlled way to meet the challenges of tomorrow. We hope that HLL will thereby be stronger and more attractive for new users. Already today, HLL is used by several infrastructure managers and signaling suppliers to state safety requirements and make mathematical models of systems for formal verification. With an active standardization community, the language will gain even more credibility and become the natural choice for many more users.
We are already looking forward to the next HLL Forum to create a thriving ecosystem of end users, suppliers, tool vendors, and academia
