A Family of Benchmarks for XML DBMSs
The benchmark provides schemas and DTDs associated with each class of XML documents. This is important since these schemas and DTDs can be exploited by DBMSs for query optimization. At the [Downloads] section, you can find complete XML Schema and DTD files grouped by document class.
The following list describes the XML documents that are included in
each document class and the XML schema/DTD files to which they conform
(XXX represents numbers and any documents ending with XXX means
these are a set of files). Clicking on each schema file shows a diagram which gives a visual presentation of the schema.
