Announcement: The operation of NSDL has been transferred to ISKME's OER Commons (effective December, 2014) - Read the news release.
This documentation describes the policies, procedures, and services that existed while NSDL was operated by UCAR.
The Digital Collection System (DCS) software, also known as the NSDL Collection System or NCS, is a Web-based tool that supports metadata management and cataloging for digital libraries. The DCS creates and manages collections of XML metadata or XML content within a data repository and is a flexible, XML-driven tool that provides a full-featured metadata editor, collection workflow processes, and a role-based permission system in support of distributed and collaborative collections management. The DCS can support any metadata framework defined by an XML schema and transparently writes metadata and collection-level information to the file system. An instance of the DCS is hosted at nsdl.org to provide cataloging services for a number of NSDL partner collections. The DCS software may also be downloaded for use locally.
Note: The NCS should not be used with Java 7.0.45 and higher until further notice. This version introduces a change that breaks XML processing in the NCS.
