XML Schema Patterns for Databinding Working Group

Charter · Patterns · Examples · Documents · Issues · Records · Schedule · Discussion · Participation · Tags

"There was significant support for the idea of a written ‘profile’ of XML Schema which would document the sweet spot for purposes of data binding, or for other specific domains. The word profile is problematic; what was meant was not a language subset, but only a definition of the sweet spot in existing processors, which would allow schema authors to get better results and better user experience when data binding tools are used, and which would tell implementors in the relevant domain which parts of schema users are most likely to expect them to support well."
-- Chairs' Report, W3C Workshop on XML Schema 1.0 User Experiences

Patterns

A pattern is a single XPath expression returning one or more XML Schema nodes. Each pattern is allocated a stable URI and classified as being either:

basic - known to work well across a wide range of state of the art databinding tools. advanced - commonly used in schemata, but currently less well supported by databinding tools. pending - yet to be considered by the Working Group.

The Working Group has developed a processor which may be used to detect patterns exhibited by an XML Schema or WSDL document.

Examples

There should be at least one example exhibiting each pattern, Each example is allocated a stable URI, presented inside XML Schema and WSDL descriptions and accompanied by one or more valid instance XML and SOAP documents. Our test suite uses the examples to assess support for patterns in databinding implementations.

We use our Issues List to record decisions on how we work, collect known interoperability issues with XML Schema and concrete patterns and examples to be included in our specifications. New issue proposals should be made against a specific document by sending mail the public mailing list. When discussing an issue in mail or on IRC, please use identifiers in the form "ISSUE-9" - see Tracker.
