The Department of Defense has gone further than just encouraging the use of open source applications by open sourcing an enterprise human resources application that has over a million lines of code, reports Computerworld.

It's likely that more open source documents will come from the DOD, as the department's top CIO, David Wennergren has set an aggressive tone on open source use. Wennergren says open source can "provide advantages" to the department's need "to anticipate new threats and respond to continuously changing requirements."

The DOD's announcment comes on the heels of the Defense Information Systems Agency's open-sourcing of an internally developed suite of administrative and workflow applications.
