Microsoft Interactive Media Manager
Microsoft Interactive Media Manager (IMM) was a collaborative media management system that leveraged Microsoft Office SharePoint Server 2007 for a web-based workflow, including both in-browser management and playback UI. It also included a RDF and OWL based metadata framework to set up relationships between media assets and facilitate tracking and complex searches. It was discontinued in 2009. References
