This document is a high-level - but developer-focused - introduction to the curation system being proposed for DSpace 1.7 It presumes knowledge of java and DSpace internals.

An initial, higher level proposal for this Curation System is available at CurationTaskProposal.

Tasks

The goal of the curation system ('CS') is to provide a simple, extensible, way to manage routine content operations on a repository. These operations are known to CS as 'tasks', and they can operate on any DSpaceObject (i.e. subclasses of DSpaceObject) - although the first incarnation will only understand Communities, Collections, and Items - viz. core data model objects. Tasks may essentially work on only one type of DSpace object - typically an item - and in this case they may simply ignore other data types (tasks have the ability to 'skip' objects for any reason). The DSpace core distribution ought to provide a number of useful tasks, but the system is designed to encourage local extension - tasks can be written for any purpose, and placed in any java package. What sorts of things are appropriate tasks?
