title = "Dublin core metadata harvested through OAI-PMH",
abstract = "The introduction in 2001 of the Open Archives Initiative Protocol for Metadata Harvesting (OAI-PMH) increased interest in and awareness of metadata quality issues relevant to digital library interoperability and the use of harvested metadata to build {"}union catalogs{"} of digital information resources. Practitioners have offered wide-ranging advice to metadata authors and have suggested metrics useful for measuring the quality of shareable metadata. Is there evidence of changes in metadata practice in response to such advice and/or as a result of an increased awareness of the importance of metadata interoperability? This paper looks at metadata records created over a six-year period that have been harvested by the University of Illinois at Urbana Champaign, and reports on quantitative and qualitative analyses of changes observed over time in shareable metadata quality.",

note = "Funding Information: UIUC provides access to descriptive metadata harvested with OIA-PMH through several portals, including the Institute of Museum and Library Services Digital Collections and Content Project (IMLS DCC), located at http://imlsdcc.grainger.uiuc.edu, and the Committee on Institutional Cooperation (CIC) Metadata Portal, located at http://cicharvest. grainger.uiuc.edu. The IMLS DCC portal harvests metadata from cultural heritage projects funded by the Institute of Museum and Library Services (IMLS). Eighty-five percent of the records in this portal represent images and 14% represent texts. The IMLS DCC project staff interacted with several data-providers regarding technical specifications and administrative information, but gave relatively little feedback to individual metadata providers regarding metadata quality. The project allowed for general presentations and publications stressing the importance of shareable metadata quality, including presentations at IMLS WebWise Conferences (Cole & Shreeves, 2004), and publications in other venues (Shreeves, Riley & Milewicz, 2006a). Conversations with data providers regarding mapping best practices were not within the scope of the project. The CIC Metadata Portal aggregates metadata describing resources held at participating CIC institutions. Most of these objects are cultural heritage resources. Construction of the CIC Metadata Portal allowed for substantial interaction between the service provider and data providers, including exchange of shareable metadata and mapping best practices, and feedback was given on a repository-by-repository basis. Table 1 provides information regarding the size of the IMLS DCC and CIC Metadata portals.",
