MARC XML: Uses and Features

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 will contain many components such as schemas, stylesheets, and software tools developed and maintained by the Library of Congress.

1. Uses

MARC XML could potentially be used as follows:

  • for representing a complete MARC record in XML
  • as an extension schema to METS (Metadata Encoding and Transmission Standard)
  • to represent metadata for OAI harvesting
  • for original resource description in XML syntax
  • for metadata in XML that may be packaged with an electronic resource

2. Advantages of MARC XML

Some MARC XML advantages are:

  • The schema supports all MARC encoded data regardless of format
  • The MARC XML framework is a component-oriented, extensible architecture allowing users to plug and play different software pieces to build custom solutions

4. Limitations of MARC XML

  • MARC Validations is not enforced by the schema but by external software
