Services: DDS

The Digital Discovery Service (DDS) provides search and retrieval services for resources that reside in an NCore repository. The service is optimized to support the rapid construction of audience-specific portals and applications and can be flexibly configured to search over any XML schema structure. A range of information retrieval features are available from the service including textual and field-based searches such as audience, subject, resource type or content standard. DDS also supports geospatial search and can be integrated with Web 2.0 applications such as Google Maps. DDS search is currently used by the DLESE library and other NSDL Pathways, services and grantees.
