For some more background on a proposed evolutionary path, see the wiki page: http://wiki.dspace.org/index.php/AssetStore The following wiki page describes the opposite approach toward a single synchronized storage resource for a DSpace archive, it puts everything in the file system. From a preservationist's point of view there's a definite advantage in choosing the "low tech" solution since file systems are much simpler than a RDBMS, and generally more robust. It doesn't take specialized software and knowledge to get your digital library back after a disaster or when migrating to a different platform; it's much easier to find software tools to operate on file systems. This is a prototype AIP implementation which is in the pipeline for a future DSpace release. It supports restoring a complete archive without the database, and migrating archival objects between DSpace archives. http://wiki.dspace.org/index.php/AipPrototype Here are some more historical notes on truly AIP-based asset stores -- the prototype above is not so ambitious, and makes compromises. http://wiki.dspace.org/index.php/RobsAssetStorePrototype http://wiki.dspace.org/index.php/JimsAssetStorePrototype http://wiki.dspace.org/index.php/RichardsAssetStoreApi -- Larry ------------------------------------------------------------------------- Take Surveys.
