Meta-information about MARC: An XML framework for validation, explanation and help systems

This article proposes a schema for meta-information about MARC that can express at a fairly comprehensive level the syntactic and semantic aspects of MARC formats in XML, including not only rules but also all texts and examples that are conveyed by MARC documentation. It can be thought of as an XML version of the MARC or UNIMARC manuals, for both machine and human usage. The article explains how such a schema can be the central piece of a more complete framework, to be used in conjunction with "slim" record formats, providing a rich environment for the automated processing of bibliographic data.
