In another Microsoft-related development being announced Tuesday, Black Duck Software said it has entered into an agreement with Microsoft in which projects from the Microsoft CodePlex open source project hosting site will be fed automatically into the Black Duck open source KnowledgeBase repository. Projects will be searchable via the Black Duck Koders.com search engine for open source and other downloadable code.
The arrangement assures ongoing coverage of CodePlex projects in the Black Duck KnowledgeBase, which is used for detecting and managing open source components in software projects, Black Duck said.
Black Duck KnowledgeBase features a repository of more than 200,000 open source projects collected from more than 4,100 Internet sites.
