XML schema analysis aims to extract quantitative and qualitative information from actual XML schemas. To this end, XML schemas are measured through systematic algorithms, on the basis of the intrinsic feature model of the XSD language. XML schema analysis is a derivative of software analysis (program analysis) and of software code metrics, in particular. The present article introduces essential concepts of XML schema analysis and applies them to the important problem of understanding XML schema usage in practice. Analyses for feature counts, idiosyncrasy counts, size metrics, complexity metrics, and XML schema styles are executed on a large corpus of real-world XML schemas.
