Hugo Bruneliere of the AtlanMod team presented Collaboro, a new tool for enabling collaborative development of domain-specific languages (DSLs). Collaboro allows users to propose and discuss changes to Ecore models, manage the community and voting process, and track design decisions. The presentation demonstrated Collaboro's features and discussed plans to integrate remote models, support DSL implementation, and improve the user interface and decision policies. The tool aims to facilitate collaboration during DSL development and evolution.
