Re: [whatwg] Comparison of XForms-Tiny and WF2

Hi Dean,

WF2 was considered harmful to XForms because it was developed without 
consideration of the use cases, intentions, architecture and methodologies 
of XForms.  The W3C process of delegating work that overlaps a working 
group to that working group and having new interested parties participate 
in that working group exists precisely to prevent this from happening.

A subset of XForms Tiny (which is only in formative stages now) is 
informed by and therefore similar to a subset of WF2.  They look similar 
to you because you have looked at a subset AND because the XForms group is 
trying in good faith to use WF2 as input to the process.  So, I would take 
your assessment to be a positive affirmation that the effort is succeeding 
at taking input from WF2.

XForms Tiny does differ from WF2 in some areas, like repetition and 
submission.  In these cases, we look at the WF2 approach as being the 
expression of a requirement for a simpler syntax.  So if we come up with a 
simpler syntax that we can happen to rationalize with the existing XForms 
architecture, then we meet the WF2 requirement while simultaneously 
providing a migration path to richer, more dynamic capabilities of full 
XForms.

Finally, note that the XForms Tiny work to date is a proof of concept, so 
the technical details will change further as the work proceeds.  For 
example, if there is no way to map a feature of XForms Tiny into XForms 
full, then one of tiny or full will be changed.  The expected result is a 
single framework for web forms development in which the feature set of 
XForms can be incrementally consumed by authors as their needs dictate.

Re: [whatwg] Comparison of XForms-Tiny and WF2







Apologies for the top post, but I have been wondering the same things 
as Matthew. As far as I can tell, XForms Tiny is very similar to Web 
Forms 2.0, yet Web Forms 2.0 was labeled as dangerous to, and 
incompatible with, XForms. Can we now assume that WF2 is acceptable 
to the XForms community? Why wasn't  XForms Tiny proposed as deltas 
to WF2?
