Alvin is a platform for archiving and publishing digital resources, for digitised physical objects as well as purely digital information. Alvin stores these resources together with descriptive metadata, according to a metadata scheme based primarily on MODS and EAD, schemas developed by the Library of Congress.
Alvin's metadata model is described here: https://wiki.epc.ub.uu.se/display/alvininfo/Formathandbok (in Swedish).
Alvin offers long-term storage of the material, and an attractive platform for publication, including a powerful search engine, persistent identifiers, and permanent URI:s through URN:NBN.
Import av data into Alvin is done through a combination of METS and MODS.
Alvin allows harvesting of metadata records through OAI-PMH Version 2, The Open Archives Initiative Protocol for Metadata Harvesting.
