摘要:The eXtensible Catalog (XC) Project at the University of Rochester will design and develop a set of open-source applications to provide libraries with an alternative way to reveal their collections to library users. The goals and functional requirements developed for XC reveal generalizable needs for metadata to support a next-generation discovery system. The strategies that the XC Project Team and XC Partner Institutions will use to address these issues can contribute to an agenda for attention and action within the library community to ensure that library metadata will continue to support online resource discovery in the future.
