Are there any XML databinding frameworks available for Ruby / Rails, such as Castor or JaXB for Java? Also are there framework such as Apache Axis for WebServices for Rails or Ruby? Regards, Harm de Laat ---

This is all I’ve been able find for Ruby to XML mapping: [http://rubyforge.org/projects/xml-mapping/](http://rubyforge.org/projects/xml-mapping/) Haven’t tried it yet. Rails has webservice stuff built in… is there something Axis does that ActionWebService doesn’t? b ---

Well the thing I wrote: [http://rubyforge.org/projects/xampl/](http://rubyforge.org/projects/xampl/) – xampl’s beginnings are as an XML binding but that is only one of the things it does. I’ll be releasing it as a plug-in for Rails soon.

Hi Bob, That’s impressive! Any idea when you’ll be making the plug-in available? I’m using Instant Rails on Windows 2K. Any thoughts re: use on that platform ? Thanks in advance.

Hey that’s cool. Write an XSLT to trasform Dia’s uml/xml format to your xml and one could generate a model from a uml diagram. Hmm, and perhaps one could write an XSLT to trasform your xml representation of the model into a DDL. b ---

Hi Bill, Thanks! I’m finishing up an application for my company that uses it. When that is done I’ll be releasing it. It is looking like a week or two. I might make a point release soon because I’ve found a couple of problems (xampl fighting with RoR) and a few bug fixes. Even without being a plug-in it is very easy to use with RoR.

Has this been released? Thanks.

The Java version of xampl has been around for a long time. There have been some pretty large scale applications written in it. We wrote a translator from xampl to and from DDL in an afternoon (it supported Oracle and Sybase) and a different one to/from mysql. I think a xampl to/from ActiveRecord Migrations would be pretty straight forward. One thing to note though, in Java the XML-in-a-file was _significantly_ faster than using a DB – and nothing comes near the performance of xml in Perst or JDBM (I still marvel at how fast those two packages are). Now Ruby is a different story of course, since Ruby really cannot keep up with Java once Java gets going, and it is definitely worth a little experiment (REXML isn’t nearly fast enough so I wrote an XML pull parser that is included in xampl, and I’ve also written a Ruby based format that is 5-10 times faster than XML (I tried YAML but there were some weird performance characteristics that I didn’t like)). As for UML to xampl… well, xampl works _very_ hard to not restrict its model and that, I think, might frustrate a UML designer. I’ve discussed the reasoning behind this someplace, but briefly, xampl programs tend to be long-running programs that transform the object structures over time. This makes it enforcement of anything like a schema a bit problematic. What I normally do is enforce schemas (if I’m going to bother at all) at ‘import’ and ‘export’ time, _not_ during the execution of the program nor when persisting the objects.

Yes, late last year. [http://rubyforge.org/projects/xampl/](http://rubyforge.org/projects/xampl/) It needs an update, but it mostly works well with Rails.
