Working with pure RDF?

[runes]

Hi forum

I've created a TB-Standard project that connects to a Sesame 2 triple
store. Now I don't see any data from the store even though the
creating process seems to work fine (I see a lot of standard OWL
stuff). I don't have any classes or defined OWL-properties in my data,
it's almost pure rdf, using the rdf:type predicate.

No matter what I do I (generic sparql-query, looking at raw triples) I
cannot see my data only the genric OWL stuff.

Doesn't TB support "pure RDF"?

Thanks,
Rune

Rune; Yes, all TopBraid products are fully RDF-compliant and will
therefore support "pure RDF".

The mechanism to find them is basically the same as Sesame - state
which named graph you refer to then find the data in that named
graph. To create such a connector in Composer New > RDF/OWL Sesame 2
Repository connection. Use the Fetch Repositories button to choose
the repository, and fill in the rest of the wizard, including the name
used for the graph in your Sesame store. The triples can base
accessed by opening the .s2n connector file, which can be imported,
etc. into other models in your Composer workspace.

Keep in mind that if you have no classes or properties, you will not see
anything in TBC views that are geared to show classes and properties.

I mean Classes view on the left. You will only see classes (such as
owl:Thing and rdfs:Resource) that are part of OWL, RDFS or RDF. This is
because there are no other classes to show. Same is true for Properties view
on the right.

Because of this, it may be difficult to start browsing your data. Here are
some of the things you can do to see your data:

1. Run SPARQL query to get some results. Click on any of the results to get
the resource and all its information presented in the Resource view - middle
of the screen. You can then continue browsing in the form by holding ctrl
key while doing mouse over resource
2. Look at the Triple view. It is not shown by default. You need to select
Window -> Show view -> Triple
3. Where you use any of the rdf/rdfs/owl resources, you can click on them in
let's say classes or properties view and see all the triples that use them.
For example, you can double click on rdfs:label to select and then click on
Find References icon (located next to the print icon) to see all triples
that include this resource

Ok - Thanks both of you. As you suggested my problem was that I hadn't
specified the named graph I wanted to use (I didn't know that Sesame
contexts were the same as named graphs). After I did this I was able
to find the missing triples.
