The Linux Foundation has released a new research paper that tries to put a price tag on the value of the open source projects it comprises, and the price they’ve come up with is eye-popping: $5 billion. That’s how much the Foundation believes it would cost for companies to have to rebuild or develop from scratch the software residing in its collaborative projects. To arrive at that figure, the Foundation analyzed the code repositories of each one of its projects using the Constructive Cost Model (COCOMO) to estimate the total effort required to create these projects. With 115,013,302 total lines of source code, LF estimated the total amount of effort required to retrace the steps of collaborative development to be 41,192.25 person-years — or 1,356 developers 30 years to recreate the code base present in The Linux Foundation’s current collaborative projects listed above.
