XForms / Schema Patterns for Databinding

The XForms Working Group had expressed an interest in what the Data Binding Working Group have been doing, so I joined their weekly teleconference to provide them with more information.

 

After I explained the background to the XML Schema Patterns for Data Binding Working Group they stated that

their particular area of interest was in the term data binding (which in XForms terminology means something different) and whether or not the basic/advanced patterns specifications would be useful to XForms. 

 

XForms bindings are used to relate components of the XForms model (which can be described by schema) to controls in the presentation layer (and XPath can be used to do this). They wondered if there was any value for them in the patterns which we had identified - perhaps from the perspective of generating an XForm based on a schema.

 

We use the schema patterns to drive generation of native programming language structures by Web Service toolkits, which isn't relevant to XForms at all. However the way the schema patterns have been identified by our group would mean that they  may be useful as a list of schema pattern uses cases which have been implemented in the real world. 

 

If a schema conforms to the basic patterns specification then I suppose it should be easier to successfully generate an XForm from that schema - but to restrict an XForms forms builder to supporting only the basic patterns specification puts us in the same position as we are with Web Service toolkits - and their inconsistent support for schema functionality. The slippery slope again!
