Traditionally, the term 'open source' describes a paradigm for software development associated with a set of collaborative innovation practices, which ensure access to the end product's source materials - typically, source code. The BiOS Initiative has sought to extend this concept to the biological sciences, and agricultural biotechnology in particular. BiOS is founded on the concept of sharing scientific tools and platforms so that innovation can occur at the 'application layer.' Jefferson observes that, 'Freeing up the tools that make new discoveries possible will spur a new wave of innovation that has real value.' He notes further that, 'Open source is an enormously powerful tool for driving efficiency.'
