Wikicat is the bibliographic catalog used by the Wikicite and WikiTextrose projects. It will be implemented as a Wikidata dataset using a datamodel design based upon IFLA's Functional Requirements for Bibliographic Records (FRBR), the various ISBD standards, the Library of Congress's MARC 21 specification, and the Anglo-American Cataloguing Rules' The Logical Structure of the Anglo-American Cataloguing Rules.
