Digital Collection System

The Digital Collection System (DCS) can be used to generate and manage metadata collections based on XML schemas. The DCS is web-based, supporting distributed collections management with protection against concurrent editing and a roles-based permissions scheme. The DCS is currently used as the collection management tool for DLESE.

The NCore version of the DCS, the NSDL Collection System (NCS), offers the ability to manage Digital Collections directly in the NSDL Data Repository (NDR). The NCS is currently used by the NSDL to manage digital collections in the NDR.

The software runs in a servlet container such as Apache Tomcat and can be installed on Windows, Linux, Mac OS or UNIX systems.
