The eXtensible Catalog Organization (XCO) has announced a grant from The Andrew W. Mellon Foundation to further develop the Metadata Services Toolkit (MST). The foundation awarded $100,000 to the Consortium of Academic and Research Libraries in Illinois (CARLI) at the University of Illinois to continue work on the MST.
eXtensible Catalog is a collection of open source components for libraries to manage metadata and build applications. As well as the MST, it includes Drupal, OAI and NCIP Toolkits.
