Z39.98 Authoring and Interchange Framework
The Z39.98 Authoring and Interchange Framework for Adaptive XML Publishing Specification (Z39.98-AI) defines a framework in which to develop XML markup languages to represent different kinds of information resources (books, periodicals, etc.), with the intent of producing documents suitable for transformation into different universally accessible formats. It uses a modular, extensible architecture to permit the creation of any number of document models, each custom-tailored for a particular kind of information resource.
