Management of Metadata Standards: The Case of UNIMARC

UNIMARC is a family of bibliographic metadata schemas with formats for descriptive information, classification, authorities and holdings. This paper describes the problem of maintenance and management of these schemas, with their online publishing for human and machine readable. This is accomplished by a Model View Controller (MVC) architecture managing the format schemas and schema descriptions in XML, as model representations, and XSLT transformations for the publishing in HTML, PDF, and other possible option. This work is an activity of a larger project toward the development of the international UNIMARC Metadata Registry, in the scope of the IFLA-CDNL Alliance for Bibliographic Standards activities.
