Open Hub

"The Black Duck Open Hub (formerly Ohloh.net) is an online community and public directory of free and open source software (FOSS), offering analytics and search services for discovering, evaluating, tracking, and comparing open source code and projects. Open Hub Code Search is free code search engine indexing over 21,000,000,000 lines of open source code from projects on the Black Duck Open Hub.

The Open Hub is editable by everyone, like a wiki. All are welcome to join, add new projects, and make corrections to existing project pages. This public review helps to make the Black Duck Open Hub one of the largest, most accurate, and up-to-date FOSS software directories available. We encourage contributors to join the Open Hub and claim their commits on existing projects and add projects not yet on the site. By doing so, Open Hub users can assemble a complete profile of all their FOSS code contributions.

The Open Hub is not a forge — it does not host projects and code. The Open Hub is a directory and community, offering analytics and search services and tools. By connecting to project source code repositories, analyzing both the code’s history and ongoing updates, and attributing those updates to specific contributors, the Black Duck Open Hub can provide reports about the composition and activity of project code bases and aggregate this data to track the changing demographics of the FOSS world."
