To be truly useful, a test suite should consist of more than a simple collection of tests. Additional information is typically required to help users understand how to execute the tests and how to interpret the results. Much of this information should be provided in the test suite documentation but some is more appropriately provided in the form of metadata about the tests themselves. Well-defined metadata can help in:
Most test suites provided by W3C Working Groups make use of some form of metadata. However, the extent of metadata usage and the forms and syntax in which metadata elements are defined varies widely from Group to Group. This document defines a minimal set of metadata elements that have proved useful in practice and attempts to standardize their names, syntax, and usage. If the use of standard metadata elements is adopted within the W3C it is likely that standardized tools will be developed to facilitate the tasks listed above.

Please note that these metadata elements are simply suggestions. Additional elements may be appropriate for your implementation. It is also likely that you will also want to define metadata elements that are associated with the entire test suite rather than with individual tests, and it may even make sense to define metadata about metadata (for example, the Dublin Core elements Date [DCES] and Language [DCES] may usefully be applied to several of the elements defined below.)

This document re-uses the Dublin Core elements where it seems appropriate. DCMI Metadata Terms [DCMI] gives an introduction to the use of metadata. For background information on the test development process and additional rationale for the the use of metadata, the QA Working Group has created a Test FAQ [TEST-FAQ]. A practical implementation of some of these principles is available in XML Query Test Suite defined by the XML Query and XSL Working Groups. (Their Guidelines for Test Submission [XQUERY-TEST] and Guidelines for Test Execution [XQUERY-TEST] provide explanations and examples.)
