"Built for archives by archivists, ArchivesSpace is the open source archives information management application for managing and providing web access to archives, manuscripts and digital objects."
ArchivesSpace 1.0 was released in October 2013. At this early stage of development, ArchivesSpace does not seem to be able to hold video or audio files, just information about these and other types of files.
ArchivesSpace was formerly two separate projects, Archivists Toolkit and Archon, which have now been merged into ArchivesSpace.
