BioRuby is an open-source bioinformatics library for the Ruby programming language that has been in development since 2000. It utilizes a centralized approach where code changes are reviewed by core committers. In recent years, efforts have been made to decentralize development through the use of GitHub and biogems - plug-ins that can be developed and maintained independently while still following standard guidelines. There are now over 60 biogems covering various domains. The biogems framework aims to further expand and motivate contributions to BioRuby.
