For more information on the tasks available based on your AIP format choice, please see the the Problem Statement & and Usage Examples section below. This section also provides good examples of how to use each of the tasks available to you in the Replication Task Suite.

...

1. General Curation Configuration: First, in your [dspace]/config/modules/curate.cfg you will want to enable & configure the Checkm Manifest tasks. (NOTE: there is a sample curate.cfg file provided in [dspace-replicate]/config/modules/curate.cfgwhich provides example settings).

   • Enable the Checkm Tasks: In the list of "Task Class implementations" (plugin.named.org.dspace.curate.CurationTask), add the following.
     REMEMBER to add a comma and backslash (", \") after each line (except the final line).

     Code Block

     plugin.named.org.dspace.curate.CurationTask = \ ... (YOUR EXISTING TASKS) ... , \ org.dspace.ctask.replicate.checkm.TransmitManifest = transmitmanifest, \ org.dspace.ctask.replicate.checkm.VerifyManifest = verifymanifest, \ org.dspace.ctask.replicate.checkm.FetchManifest = fetchmanifest, \ org.dspace.ctask.replicate.checkm.CompareWithManifest = auditmanifest, \ org.dspace.ctask.replicate.checkm.RemoveManifest = removemanifest

   • Give Each Task a Human-Friendly Task Name: Under the ui.tasknames setting, give each of the above Tasks a human-friendy name. Here are some recommended values, but you are welcome to tweak them.
     REMEMBER to add a comma and backslash (", \") after each line (except the final line).

     Code Block
     ui.tasknames = \ ... (YOUR EXISTING TASK NAMES) ... , \ transmitmanifest = Transmit Checkm Manifest to Storage, \ verifymanifest = Verify Checkm Manifest exists in Storage, \ fetchmanifest = Fetch Checkm Manifest from Storage, \ auditmanifest = Audit against Checkm Manifest, \ removemanifest = Remove Checkm Manifest from Storage

   • Optionally Create a Task Group: Finally, if you'd like to create a Task Group for these tasks, you can create a group named "checkm" and add them all to it. The below is just an example for how you may wish to set the ui.taskgroups and ui.taskgroup.*settings. It creates two Task Groups: (1) a "General Purpose Tasks" group for a few default DSpace Curation Tasks, and (2) a "Checkm Validation Tasks" group for all these new Replication tasks.

     Code Block

     # Tasks may be organized into named groups which display together in UI drop-downs ui.taskgroups = \ general = General Purpose Tasks, checkm = Checkm Validation Tasks # Group membership is defined using comma-separated lists of task names, one property per group ui.taskgroup.general = profileformats, requiredmetadata, checklinks ui.taskgroup.checkm = transmitmanifest, verifymanifest, fetchmanifest, auditmanifest, removemanifest

Problem Statement

...

and Usage Examples

We can suppose our data curator has identified a collection of items in her DSpace repository consisting of high-value, born-digital, and unique/irreplaceable (not held elsewhere) content. She prudently wishes to insure against catastrophic local loss of this content by keeping a copy or replica of this collection elsewhere. She'd prefer to replicate all her DSpace content, but realizes that storage costs over long periods has made her administration wary, so decides to begin with this collection.
