Metrics for XML Projects #5: Structured Document Complexity Metric
by Rick Jelliffe
Structure Document Complexity Metric
The Structured Document Complexity Metric asks the question "How complex is this document set or schema?" for the purposes of project estimation and management. The metric works for a sampled set of documents (XML or SGML) and for grammar-based schemas as well. A schema that perfectly describes a set of document instances will have the same metric as that set, and so can be used to judge how optimal a schema is.
