Bethesda, Md., USA - (June 7, 2002) NISO, the National Information Standards Organization, has released a draft of Z39.87, the Data Dictionary for Technical Metadata for Digital Still Images for trial use. NISO collaborated with the Association for Information and Image Management (AIIM) in the development of this standard.
Two overarching goals led NISO and AIIM to develop this data dictionary. The first is to identify the data elements that would be used by applications to control transformations of images against stated metrics (or "anchors") for meaningful quality attributes such as detail, tone, color, and size. The second is to propose elements that would be used by digital repository managers, curators, or imaging specialists to assess the current aesthetic and functional values of a given image or collection of images. The purpose of this data dictionary is to define a standard set of metadata elements for digital images. Standardizing the information will allow users to develop, exchange, and interpret digital image files. The dictionary has been designed to facilitate interoperability between systems, services, and software as well as to support the long-term management of and continuing access to digital image collections.
Co-chairs Robin Dale (RLG) and Oya Y. Reiger (Cornell University) led this standards committee which included Janet Gertz (Columbia University), Meg Bellinger (OCLC), Dr. Marianne Doerr (Leitung VD17 und Muenchener Digitalisierungszentrum), Betsy Fanning (AIIM International), Dr. Franziska Frey (Image Permanence Institute, Rochester Institute of Technology), Erich Kesse (University of Florida), Matt Kirschenbaum (University of Kentucky), Kelly Russell (University of Leeds), Linda Tadic (HBO), Colin Webb (National Library of Australia) and Herbert J. White (LDS Church-Family History Division). This proposed national standard is being released as a Draft Standard for Trial Use for the period June 1, 2002 through December 31, 2003. Like all NISO standards documents, this document is available for downloading free from the NISO web site (www.niso.org).
NISO is the only U.S. group accredited by the American National Standards Institute to develop and promote technical standards for use in information delivery services providing voluntary standards for libraries, publishers and related information technology organizations. All NISO standards are developed by consensus under the guidance of experts and practitioners in the field to meet the needs of both the information user and the producer.
