Subject: RE: [set] Groups - An Example Use Case (OASIS.SET.TC.METU.UseCase.doc)uploaded

Part II here - I realized this is actually simpler than I'd noted below in the last step - no need to generate XSLT to do the mapping (that's intellectually stimulating but a much uglier tar pit to step into)!
In the CAM toolkit we already have XSLT that takes a target format - and generates an XML instance of that.
(Its used for XML test instance generation of the original XSD schema).
The XML instance generator has a content hinting feature that puts values into that target format based on suggestions by XPath name.  So to make this all work - the content hinting logic just needs to open up the original source XML instance - and use the values out of that to populate the output. 
I say "just" obviously there's some work there to crossreference from the target to the source - locate the matching item - and then pull it from the correct spot in the XML instance - but that's all just XSLT magic to make that work.
Essentially this is just like an automated content hinting system - with values to be inserted in the right places in the output.
We shall see how this plays out!
Thanks, DW

Both this example and the one Stephen posted exhibit similar needs.  Format A, Format B, similar domain characteristics - need crosswalk between them.
Conceptually I'm seeing the following approach can work. 
I will try and work something up on this over the next few of weeks - but my plate is very full at the moment.
Conceptual approach -
Step 1 - map targets into abstraction format
Step 2 - align to common terms dictionary (this can be part automated and part manual)
Step 3 - consolidate into use templates for each target
Step 4 - parse templates creating mapping A->B and B->A based on semantic information in templates
Notice that quite a lot of this is already available in the current CAM toolkit.
Mechanically this translates to:
Format A XSD -> ingest to CAM template
Format B XSD -> ingest to CAM template
Run XSLT against CAM CXF abstraction XML and compare to master dictionary - matching on names - generate crosswalk (we have this available for NIEM.gov example - would need to create similar dictionary for UBL and other domains).
XSLT -> CAM -> dictionary -> crosswalk XML (that's also can be opened automagically as Excel spreadsheet)
Have an example I can share using OASIS EDXL and NIEM dictionary and Excel
(I'll post something on that - so you can all try it yourselves - assuming you can drive XSLT).
Integrate results of matching crosswalk back into CAM template in <Extensions> section - with match to master dictionary called out for each element and attribute.
Crosswalk + CAM -> new template (manual editing)
Adapt the existing XSLT code that parses XML together with a CAM template - to instead generate simple XSLT mapping code (actually this is something Martin's been talking about is generating XSLT validation code... but that's another whole topic - we actually have an XSLT validating version of CAM in beta too - lots of xslt code here we can re-purpose to SET tasks!).
I can mock up a skeleton on this - proof of concept - then see what else is needed at that point.   Where it gets interesting is how smart you can make the matching and reformatting... I'll start with dumb, with manual intervention for those things that don't match easily.
As usual you can get 80% of this working with 20% of the effort.  I'm signing up here to do the 20% first! ; -)
At least after this exercise we can all see where the challenges are!
Thanks, DW
