micala is a comprehensive lecture archiving system, including components for recording, processing, archiving and disseminating multimedia web lectures.

micala has evolved since 2000 from multiple projects of the U-M ATLAS Collaboratory Project and CERN, and is now used in production at both of those institutions. Part of its development was funded by the US National Science Foundation.

    micala is an acronym for University of Michigan and CERN Automated Lecture Archiving

    In 2000, Professor Homer A. Neal at the University of Michigan founded the U-M ATLAS Collaboratory Project, whose mission is to "study and advance the technologies and practices required for the organization and execution of modern, large-scale collaborative research experiments." This has included developing technologies for videoconferencing and lecture archiving.
