Chemical Markup, XML, and the World Wide Web. 4. CML Schema

Abstract

A revision to Chemical Markup Language (CML) is presented as a XML Schema compliant form, modularized into nonchemical and chemical components. STMML contains generic concepts for numeric data and scientific units, while CMLCore retains most of the chemical functionality of the original CML 1.0 and extends it by adding handlers for chemical substances, extended bonding models and names. We propose extension via new namespaced components for chemical queries, reactions, spectra, and computational chemistry. The conformance with XML schemas allows much greater control over datatyping, document validation, and structure.
