Hi Tim,
unsurprisingly, I would now recommend ADS/JavaScript. I am attaching an
example to get you started. Put it into your EDG Studio workspace, edit
the file and open its Swagger UI on the Reports tab:
The (minimal) code for this output is:
To generate XSD from an ontology, the idea would be that you traverse
all classes (owl.everyClass()) - here I did sh.everyNodeShape() and then
recursively write functions that process it class by class, e.g. to
create XSD field declarations for all datatype properties etc.
This starting point may give you some ideas. The alternative would be to
use SWP in a similar manner, but it the code would be much harder to
maintain and you don't have as much flexibility as a full programming
language like JavaScript.
Regards,
Holger

Hi,
I have a need to express an ontology as specified by an XML schema.
This schema is defined by a vendor to represent a class model in their
proprietary schema.
Many years ago, I used SWP and the ui:instance view property to
assemble HTML pages to drive a wiki straight from the old TopBraid
Live product. I was able to define how each instance should render
itself at the class level. I think the same thing will work here
where I define how Node Shapes and Property Shapes should represent
themselves in this proprietary XML schema.
Given all the changes to TBC/EDG since I last did this (2011???), what
is the current best approach to expressing an RDF/OWL/SHACL structure
as an XML schema? SWP? ADS/Javascript?
Thanks in advance for your input,
Tim
