The DLESE library is powered by the Digital Discovery System (DDS). The Web-based services and APIs that are available for accessing the DDS repository and search capabilities are summarized below.
The Search Service API is a RESTful API for searching and retreiving items that reside in a DDS repository, and is available from the Digital Discovery System (DDS) and the NSDL Collection System (NCS). Service requests are expressed as HTTP argument/value pairs and responses may be returned as XML or JSON.
The Repository Update Service (DDSUpdateWS) is a RESTful API for making updates to a DDS repository. Authorized clients may use the service to create, update and delete collections and items within a DDS repository. Note that this service is disabled for the DLESE library.
