Black Duck Software has acquired Ohloh.net, the largest free public directory of open source software. Ohloh's directory contains information aggregated from over 250,000 public code repositories, projects and forums.

Black Duck will maintain and enhance the Ohloh web site and will ultimately combine Ohloh and Koders.comto establish a comprehensive, free resource for developers to find, create, use and manage FOSS.

Black Duck plans to use the acquisition to help enhance and expand FOSS adoption by making it easier for developers to tap the huge body of high-quality code in open source projects, and collaborate with their peers through the Ohloh community. By working with the FOSS community, including forges, foundations and other code repositories as well as individual projects and developers, Black Duck says it will expand and enrich Ohloh with improved data and new productivity tools. Black Duck plans on integrating Ohloh assets with Black Duck's free code search site Koders.com, and will create a single web destination that developers can turn to as a trusted source of FOSS knowledge.
