DSpace bundles a small number of tasks of general applicability. Those that do not require configuration (or have usable default values) are activated by default to demonstrate the use of the curation system. They may be deactivated by means of configuration, if desired, without affecting system integrity. Those that require configuration may be enabled (activated) by means editing DSpace configuration files. Each task - current as of DSpace 4.0 - is briefly described in this section.

Link Checkers

Two link checker tasks, BasicLinkChecker and MetadataValueLinkChecker can be used to check for broken or unresolvable links appearing in item metadata.

This task is intended as a prototype / example for developers and administrators who are new to the curation system.

These tasks are not configurable.

Basic Link Checker

BasicLinkChecker iterates over all metadata fields ending in "uri" (eg. dc.relation.uri, dc.identifier.uri, dc.source.uri ...), attempts a GET to the value of the field, and checks for a 200 OK response.
Results are reported in a simple "one row per link" format.

Metadata Value Link Checker

MetadataValueLinkChecker parses all metadata fields for valid HTTP URLs, attempts a GET to those URLs, and checks for a 200 OK response.
Results are reported in a simple "one row per link" format.
