    Abstract
    The Open Video Digital Library (OVDL) provides digital video files to the education and research community and is distinguished by an innovative user interface that offers multiple kinds of visual surrogates to people searching for video content. The OVDL is used by several thousand people around the world each month and part of this success is due to its user interface. This article examines the interplay between research and practice in the development of this particular digital library with an eye toward lessons for all digital libraries. We argue that theoretical and research goals blur into practical goals and practical goals raise new research questions as research and development progress-this process is akin to walking along a Möbius strip in which a locally two-sided surface is actually part of a globally one-sided world. We consider the gulf between the theories that guide current digital library research and current practice in operational digital libraries, provide a developmental history of the OVDL and the research frameworks that drove its development, illustrate how user studies informed its implementation and revision, and conclude with reflections and recommendations on the interplay between research and practice.

    Abstract
    Much of the usefulness of digital libraries lies in their ability to provide services for data from distributed repositories, and many research projects are investigating frameworks for interoperability. In this paper, we report on the experiences and lessons learned by iLumina after importing IMS metadata. iLumina utilizes the IMS metadata specification, which allows for a rich set of metadata (Dublin Core has a simpler metadata scheme that can be mapped onto a subset of the IMS metadata). Our experiences identify questions regarding intellectual property rights for metadata, protocols for enriched metadata, and tips for designing metadata services.
