Sharing methodological knowledge with REGAL: "requirements engineering guide for all"

This paper presents a repository-based tool for sharing RE (empirical or theoretical) methodological knowledge, and improving it collaboratively. Methods are documented in our tool with methodological patterns. The originality of our tool is threefold: (i) the structure of methodological patterns can evolve, (ii) it is also possible to adapt the structure of the pattern repository, and (iii) configuration management features are proposed to enrich the content of the repository collaboratively.
