DDS ODL Search Service

A new version of this service is available. The documentation here is for a previous version. Please refer to Current Search Web Service for new application development.

The DDS Open Digital Library (ODL) Search Service is an API that extends the Open Archives Initiative Protocol for Metadata Harvesting (OAI-PMH) to allow for textual searching of the DDS repository content.

The DDS ODL service provides a rich search API and gives full access to the metadata in DDS's collections. Metadata is available for educational resources, annotations, news & opportunities and collections. The service supports textual searching over metadata and content, searching by date and field, sorting by date and field, discovery of the controlled vocabularies that are part of the library including grade ranges, subjects, resources types and content standards, checking for the existence of a URL, and other functionality.

The service is illustrated and described formally here:

  • ODL Search Service Explorer - The ODL Search Service explorer allows you to issue each of the available requests to the service and view the XML response using your web browser.
