This service enhancement for TDL-hosted DSpace users is only provided for TDL members using Digital Preservation Services (DPS). |
If any DPS member would like to use their digital preservation storage for preserving their DSpace content, they can work with TDL to configure and implement a modified version of DSpace's Replication Task Suite (RTS). Documentation for the RTS as it has been applied to DuraSpace's DSpace and DuraCloud instances can be found here. The TDL implementation offers limited support for the RTS, as documented on this page.
Members will work with TDL to create and name a space or spaces in their DuraCloud dashboard which will be the target for uploading their DSpace content. TDL will install the TDL-modified RTS to the institutional repository and train the member to use the system. By default, AIPs are generated in the default DSpace AIP Format, but there is also an option to generate BagIt-based AIPs using the Library of Congress specification instead of using the default DSpace AIP format. TDL and the member will decide this during the configuration and set up of their TDL-RTS.
TDL-RTS will only overwrite content already in DuraCloud if the local and destination checksums differ. If that's the case then it will transfer the new AIP generated from DSpace. And any AIPS generated from DSpace locally that don't exist in DuraCloud will be transferred. So it adds new content whenever transmit is run.
Once a member has been set up with the TDL-RTS in their TDL DSpace, the following are the basic steps to preserve your content in your digital preservation store.
The User can Perform this task immediately in the DSpace Admin UI, or, if the collection is rather large, they may instead Queue the task for later execution by using the queueing facility available in the curation system.
Please note that the Transmit AIP(s) to Storage task, like all other replication tasks, operates on whatever DSpace object(s) they are given. Thus, if the object is a collection, the task creates (and transmits, of course) an AIP for the collection object itself (metadata and logo), as well as AIPs for each item in the collection. If the task is given an identifier for a single Item, then only one AIP will be created and transmitted.
DuraSpace created a video to support Users running RTS tasks. Keep in mind, only the three options mentioned above are available to TDL Digital Preservation Services members.
For support with restoration of content to DSpace from a Digital Preservation Storage location, please contact TDL support (support@tdl.org) so they can schedule the task.
