The Shippensburg University Archive uses Islandora and ArchivesSpace for their digital management.
ISLANDORA:
Islandora is an open-source digital asset management system. It is a way to manage digital collections that can be accessed and viewed by the public. The metadata standard used in IS is MODS, Dublin Core, etc. It supports any XML standard.
ARCHIVESSPACE:
ArchivesSpace is an open-source archives information management system that Shippensburg University Archives uses to manage and display the descriptive finding aids created for each record group and other manuscript collections. We can also use it to manage our accessions. The metadata standard used in AS is DACS (Describing Archives: A Content Standard), but it will support other standards such as MODS, XML, Dublin Core, etc)
Both DAMs require extensive knowledge and can consume a great deal of an archivists' time.
