You can track the origin of each triple in TBC if you move/hover your
mouse over the icon of the triple.
Right, what I sent before is by itself no explanation for the
rdfs:subClassOf owl:Thing triple. Both the TTL and the RDF/XML file from
that site contains that triple in a second definition (see for example
https://www.w3.org/ns/prov.rdf)
<owl:Class rdf:about="http://www.w3.org/ns/prov#SoftwareAgent";>
<rdfs:label>SoftwareAgent</rdfs:label>
<rdfs:subClassOf
rdf:resource="http://www.w3.org/2002/07/owl#Thing"/>
which looks like an error - you may want to contact the relevant W3C
group about this.
In TTL there are actually two definitions:
:SoftwareAgent
a owl:Class ;
rdfs:isDefinedBy <http://www.w3.org/ns/prov-o#> ;
rdfs:label "SoftwareAgent" ;
rdfs:subClassOf :Agent ;
:category "expanded" ;
:component "agents-responsibility" ;
:definition "A software agent is running software."@en ;
:dm
"http://www.w3.org/TR/2013/REC-prov-dm-20130430/#term-agent"^^xsd:anyURI ;
:n
"http://www.w3.org/TR/2013/REC-prov-n-20130430/#expression-types"^^xsd:anyURI .
:SoftwareAgent
a owl:Class ;
rdfs:isDefinedBy <http://www.w3.org/ns/prov#> ;
rdfs:label "SoftwareAgent" ;
rdfs:subClassOf owl:Thing ;
:category "expanded" ;
:component "agents-responsibility" ;
:definition "A software agent is running software."@en ;

but this doenst seem to entail the same ? (how do I search in TBC for
the graph containing a subject, or with a specific namespace ?)

Maybe you have a different copy?

note that if i import the PROV ontology, but dont include any
subclass axioms, it shows "SoftwareAgent" as the sole subclass of
owl:Thing. I dont see this declared specifically in prov code.

No, it doesn’t find anything arbitrary. By default, the root
of the tree is owl:Thing (you can change it). The tree will
display all subclasses of its root and then for each child,
its subclasses and so on.
If owl:Thing has no subclasses, you will see nothing but
owl:Thing.

Ok, I was about to respond... right, the class tree in
the SWA applications needs to use asserted
rdfs:subClassOf triples - the automated inferences that
TBC makes are not visible.
That seems a pretty critical piece of behaviour which ought
to have big(ger?) flags in the documentation - and it seems
to choose something arbitrary if it doesnt find anything?
(maybe it create a help message as a virtual class to inform
if no subclasses are present.)
OK - is it possible then for it to be clever and import a
SPIN rule which finds what entities are present then asserts
the necessary subclass axioms? Does such a thing already exist?
I would appreciate a quick recipe for exactly how to do this
- I havent yet got up to working out how to automate SPIN
processing - I want some "system" rules to happen
automatically but be able to invoke other SPIN rules
manually in SWP interfaces FYI

on another front:
file 1( which shoiws correct class hierarchy in EDG,
but doesnt show imports in TBC )
TBC assigned a default baseURI
file:///C:/repos/surround/provrules/pizza_example/out/pizza_prov_out.ttl
when I change this in the baseURI and named Ontology in
the file to:
http://www.co-ode.org/ontologies/pizza/pizza_prov_out/
<http://www.co-ode.org/ontologies/pizza/pizza_prov_out/>
TBC then displayed import correctly.
I guess the owl:imports statements were dangling off the
<http://www.co-ode.org/ontologies/pizza/pizza_prov_out/>
<http://www.co-ode.org/ontologies/pizza/pizza_prov_out/>
resource which was not identical to the declared base
URI. It seems that you have fixed that.

Ahh - it seems top have dumped the screenshots...
I'm talk about two ontologies which import the same
class model showing different set of classes in the
class navigator pane (North-west) in a SWA template
- but the same classes if i open them in TBC

Sorry, I need more details to be helpful.
Are you referring to the class hierarchy view,
or what is shown on the main area (forms)? What
sort of instances are you looking at?
