The intent of the CDP Dublin Core Metadata Best Practices (CDPDCMBP) is to provide guidelines for creating metadata records for digitized cultural heritage resources that are either born digital or have been reformatted from an existing physical resource, such as photographs, text, audio, video, three-dimensional artifacts, etc. This document uses the Dublin Core element set as defined by the Dublin Core Metadata Initiative (DCMI).Application of these best practices will result in standardized Dublin Core records that: (1) enhance online search and retrieval accuracy in local and shared databases (i.e., union catalogs); (2) improve resource discovery capabilities; (3) improve quality control of metadata records; facilitate inter-institutional interoperability. These guidelines have been created to address the needs of a diverse audience of cultural heritage institutions composed of museums, libraries, historical societies, archives, etc. This document seeks to accommodate different backgrounds and metadata skill levels of those charged with creating metadata records, including catalogers, curators, archivists, librarians, Web site developers, database administrators, volunteers, authors, editors, or anyone interested in creating digital libraries of cultural heritage materials. We have attempted to provide clear and concise explanation of terms and concepts, as well as examples describing the varied resources found in cultural heritage institutions.
