from authority control to linked authority data
DESCRIPTION
The presentation describes the tradition of authority control in the German speaking countries, with its former authority files, SWD, GKD, PND, and EST, and the recently finished project "Gemeinsame Normdatei" (GND). During this project, the files have been merged into one integrated authority file, structured by one common format. The presentation informs about the partners, the principles, the working packages and the results of the merging process, as well as the next steps to be taken. While trying to balance the needs of legacy data and existing systems and workflows with MARC as a base structure for the cataloging format, an approach was taken that was driven by the "Functional Requirements for Authority Data" (FRAD). A specific focus was put on relationships and their coding, which may be seen as a step into the Linked Data world. Thus, the GND and its underlying concepts can be of significance as a contribution to the "Bibliographic Framework Transition Initiative".TRANSCRIPT
