Introduction of the Open Source Census

In 2008, OpenLogic plans to launch The Open Source Census, which will expand the statistics collected and reported on enterprise open source adoption. The Open Source Census, announced by OpenLogic in December 2007, is a collaborative initiative designed to provide enterprises a way to easily inventory the open source software installed on their machines, and anonymously submit that data to The Open Source Census. Data collected in The Open Source Census will be aggregated and shared publicly on the Internet and will also be available to the enterprises who contribute data.
