The Library of Congress' Network Development and MARC Standards Office is developing a framework for working with MARC data in a XML environment. This framework is intended to be flexible and extensible to allow users to work with MARC data in ways specific to their needs. The framework itself includes many components such as schemas, stylesheets, and software tools.

Tools & Utilities

The following are examples of the types of tools LC is considering maintaining. Some of these are recently written by NDMSO or have been adapted from tools built by others.

• MARC21 to MARC XML Conversion
  • MARCXML Toolkit

  The MARCXML toolkit is a set of Java programs which allow users to convert to and from the MARC file format (including full character set converstion) and other formats available in the MARCXML architecture. The toolkit requires Java and works best with Java 1.4. If using a earlier version of Java, you need to modify the marcxml.bat file to include an xml parser in the classpath. Unzip the marcxml.zip file in a directory and run marcxml.bat for more instructions. Make sure java is in your PATH. In this version the stylesheets and character conversion mappings are downloaded via http from LC's website therefore Internet access is required when using these utilities.
