RE: Progress on the XSD to CAM template generator toolkit

["David RR Webber \(XML\)" <david@drrw.info>]

Tracy,
 
Good Q's.  We do have the cam-dev list - so I'm cc:ing that here.
 
The sign-up for that is here:- http://www.oasis-open.org/mlmanage/
 
I've also done a general release of the toolkit today to the wiki:
 
 http://wiki.oasis-open.org/cam/XSD_and_CAM
 
For you Q's - extending the base templates.  First alot of these conditional requirements can be handled in XPath using the conditional and context tools in CAM.
 
So crossfield validations such as comparableHomeDistanceInRange() , appraiserLicenseActive() are probably relatively simple XPath assertions - if(this and that) checks.
 
For more complex decisions (especially requiring computations - like totalApplicantSalaries() - then you have a couple of choices.
 
We do provide the <Extensions> section for this purpose.  So using that you can either call your own Java routines, or use a general purpose rules engine such as JRules, and pass that the output from the CAM processor for onward validation checks.
 
Another thing you could do more simply is to call an xslt routine that could perform additional post-validation checks and transformations.  The CAM engine is all setup to do that with two xslt branches - one for successful validation, and the other for error found.
 
Hope that is helpful.

Thanks, DW

Thank David.


Are the CAM builtins extensible? For example, makeRepeatable() ,makeOptional() ,etc. makes CAM very attractive. But what if someone wanted to create their own buildins to be used : comparableHomeDistanceInRange() , appraiserLicenseActive() , etc.

p.s. If there is a mailing list for CAM and you prefer; I would be glad to take these questions to the list.


Thanks,
Tracy

Tracy,

Attached updated ZIP.

I don't have access to my ftp site here - will do that tonight when I get home.

Thanks, DW

Thanks David. I'm excited to give this a try.

Subject: Progress on the XSD to CAM template generator toolkit

Tracy,

As promised I'm sharing with you progress here on the xslt toolkit that processes an XSD and automatically builds the equivalent CAM template.

We've been running this in both Stylus Studio and OxygenXML using Saxon 9 and xslt v2.

It is working remarkably well on the OASIS EDXL/CIQ schema set. It's pretty easy to use - the readme file gives you the couple of steps needed.

You can review that here as a ZIP file of the xslt and sample XSD:

<http://www.drrw.net/projects/DHS/xsd-2-cam/xsd2cam.zip><http://www.drrw.net/projects/DHS/xsd-2-cam/xsd2cam.zip><http://www.drrw.net/projects/DHS/xsd-2-cam/xsd2cam.zip><http://www.drrw.net/projects/DHS/xsd-2-cam/xsd2cam.zip><http://www.drrw.net/projects/DHS/xsd-2-cam/xsd2cam.zip>http://www.drrw.net/projects/DHS/xsd-2-cam/xsd2cam.zip

example XSD - EDXL emergency management schema:

<http://www.drrw.net/projects/DHS/xsd-2-cam/edxl-have_pr03-r02.zip><http://www.drrw.net/projects/DHS/xsd-2-cam/edxl-have_pr03-r02.zip><http://www.drrw.net/projects/DHS/xsd-2-cam/edxl-have_pr03-r02.zip><http://www.drrw.net/projects/DHS/xsd-2-cam/edxl-have_pr03-r02.zip><http://www.drrw.net/projects/DHS/xsd-2-cam/edxl-have_pr03-r02.zip>http://www.drrw.net/projects/DHS/xsd-2-cam/edxl-have_pr03-r02.zip

As always - I have some additional enhancements I want to finish though before doing a public release.

And I need to complete testing on a full range of OASIS schemas - before I'm completely confident we have it ready.

One thing I'm working on is a "wantlist" xml file that filters down the entire XSD to exclude items you are not using.

Think another week here will complete everything on the "to do" list.

Anyway - wanted to let you have a sneak peak at this - as I'm rather excited about the capability here to really jump start folks getting started with CAM templates.

The plan is to integrate this into the Eclipse editor as a 'wizard' once we have the xslt all completed.

Let me know how it works for your own XSD's.

Cheers, DW
