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.


Current Work in Progress

  • inputHelpers - a generic mechanism for third-party plugins that help calculate a value for a metadata field. The SMILE project used this mechanism to integrate their "geo-footprint" tool, which helps users to create bounding box using google maps, and then inserts the bounding box values into the appropriate metadata fields.

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.
