I should add the that importing of XML into triples with a namespace based on the file's name and location is the same SXML that Gokhan describes here.

The best way in TBC related to manipulating XML files at the moment is to use SXML. You can open an XML file as an SXML ontology either by double-clicking on it in TBC or right-clicking on it and selecting "Open With... > TopBraid (Semantic XML Documents)". You can then see all XML instances as triples under Associations View (from the menu, select Window > Show View > Associations), where then you click on "Select property..." from the toolbar, and select "composite:child". You can see the instances, and what classes and properties they get. > Import it into a RDF file? If you want to get more sophisticated, and want to control which class that an instance has as its type, then you can construct an ontology where you define the sub-class hierarchy and attach sxml:element annotations on the classes, with element tag of the instance as the value of the annotation. Then, you can import an XML file through Imports View, and the SXML instances will have these annotated classes as their type. If you want more sophisticated and more customized structure, you can write SPIN rules (SPARQL Rules), where you can construct new triples on the existing SXML triples. > Or just open the XML file in TBC and import other vocabs?

When an XML file is imported into an ontology, it is already treated as an SXML ontology. > Oh, how hard would it be to take one large XML file and also > produce individual files for each defined person in the XML version of > the GEDCOM - so I would have one large RDF file and several smaller > files? The answer is to use SPARQLMotion, where there are modules for imports, iterations and exports to various formats.
