I wouldn't be so categorical :) We generate all the UI layouts straight from RDF/XML using XSLT 2.0: https://github.com/AtomGraph/Web-Client/blob/master/src/main/webapp/static/com/atomgraph/client/xsl/bootstrap/2.3.2/layout.xsl
The prerequisite is that RDF/XML structure is predictable like Jena's output, not any RDF/XML that is possible in the wild. We have actually proposed to standardise this in some form: https://www.w3.org/community/rax/wiki/Draft_Material#RDF.2FXML_.22plain.22_profile_suitable_for_XSLT_transformations On Wed, Oct 11, 2017 at 9:16 AM, Olivier Rossel <olivier.ros...@gmail.com> wrote: > I don't see any practical usage of managing RDF data via its XML > serialization through XML tools. > In my town, a huge project tried to store graph data in a XML > database.
