Method for solving prepress catalog data localization

The invention discloses a method for solving prepress catalog data localization, comprising the steps of: 1) analyzing state map and CALIS (china academic library & information system) cataloging rules and finding out similarities and differences of a catalog header section, a directory section and a data field in the two rules; 2) marking the similarities as common processing data and analyze the differences to find out corresponding processing methods; 3) designing a service system which can be compatible with the two rules; 4) processing data by using the compatible service system and storing the data according to the CALIS rule, the state map rule and simple catalog data including ISBN (international standard book number), price, title, author and classification code included; 5) purchasing and acquisitioning books by utilizing the simple catalog data, or further deciding contents of the books upon the detailed catalog data to purchase the books accurately; and 6) setting rule options in the service system of the purchasing unit, using the simple catalog data to match with the detailed catalog data automatically and downloading to complete the catalog data. The method for solving the prepress catalog data localization disclosed by the invention unifies the cataloging rules and continues the former two cataloging rules, reducing the data disorder due to the change of the cataloging rules.
