76% of our code is open-source code

Over a six month period we (Nets=old BBS) analyzed usage of open-source (code) by collecting data from 12-14 large development projects based on Java. Most of these projects have been initiated in connection with the Stay project. We have extracted the following vital statistical data from these projects

The source code deployed:

• In house developed source code (including libraries)
• External open-source code (including libraries)
• External closed source code (including libraries)

The result was amazing, data shows that approximately 76% of code is open-source code, less than 7 % is closed external code, and 17% is developed in-house. The external code is reduced day by day as we convert our old code from WAS (WebSphere Application Server, from IBM ) to Jetty.
