Re: [jibx-devs] xsd2jibx in upcoming RC0

I don't see much future for the current code. One problem is that this uses JiBX data binding for reading the schema as well as writing the generated binding; for working with the generated binding I think this is fine (and it's what I do in the binding object model), but for reading the schema I don't think data binding is necessarily a great approach. The code also has many quirks about how it handles the binding and code generation, and the actual code generation uses some JaxMe code that I don't find very impressive. I think it'd be quicker to start over than to extend the existing code to support the missing schema features.

Now that I've backported the binding object model to 1.0 it's probably cleaner to build on that, and for the actual code generation I'd prefer something more flexible than the JaxMe model (perhaps Velocity templates, or Castor generation, or Eclipse code generation, or ...).

The witsml.org schema looks pretty complex. How are you handling features like complex type extensions/restrictions, enumerations, etc.? If you've gotten this type of thing working with the current CVS code perhaps there's more hope for it than I'd imagined.

Hi devs,

  just wondering about the plans for xsd2jibx - from browsing
the list archives it seems that it might be destined to stagnate.

My project involves a large schema of about 100 business objects
that is in flux as the standard develops.  A tool like xsd2jibx
is invaluable to me.

I have the current CVS and I've made a bunch of fixes to get the
current version limping along.  Just wondering if Cameron is
picking up the reigns or if anybody else is on the case.

PS - FYI the schema I am working with is from witsml.org - it
is a drilling well information transfer standard that uses
every XMLSchema trick in the book.  If you want a *big* commercial
schema to test with this is a good one
