Bruce; I think you will find that the triples are there, but the data
you show just doesn't have any modeling elements - class and property
definitions. This is perfectly legitimate for RDF data. You can
always find out what data is in a model with the Triples view. Go to
Window > Show View > Triples. A view will appear and you can select
the namespace you want to view.
Given that you are looking into SPARQL, to find all triples you can
always run a SPO query:
SELECT *
WHERE
{ ?s ?p ?o
}
The SPARQL View will limit you to the first 1000 matches (which can be
modified in Preferences), so it is safe to run across large data
sets. If you run this with "Run on base model only" (mode icon in
upper-right of SPARQL view) you will get only the triples defined in
the currently open model.
