RE: Fuseki 2.4.0 web user interface
I got the answer of my question of my experimentation. I obtained a solution in
the edit window of query (in the front end).
I just selected every graph, selected all the triple inside it and deleted.
Saving this would result is deleting all entries. The fron end would update and
remove all graphs with 0 entries once I restart Fuseki 2.4.0 server.
This is one solution, there may be better ones.
Regards and thanks to all who helped.

Hi,
I added a new dataset in Fuskei 2.4.0 and added one line tdb:unionDefaultGraph
true; at the end of the configuration ttl file.
This started working and gave desired results for classes in my OWL file.
One question regarding graphs loaded into my persistent dataset that I had
defined..What is the way to delete my experimental graphs from the dataset
in Fuseki 2.4.0?

Can you please share the output of the general query? Jjust that we can see
whether the triples have been loaded into a named graph or something which ta
least is not the default graph.
Hi Lorenz,
What I meant by Andy's query statement working is that it returned all the 11
triples of my turtle file. His suggested query contained a union of graph
within the SELECT statement.
SELECT * { { ?s ?p ?o } UNION { GRAPH ?g {?s ?p ?o } } }
Next, I tried the OWL version of the same file both in OWL and RDF/XML format
with the query statement:
prefix owl: <http://www.w3.org/2002/07/owl#> prefix rdfs:

SELECT DISTINCT ?class ?label ?description WHERE {
?class a owl:Class.
OPTIONAL { ?class rdfs:label ?label}
OPTIONAL { ?class rdfs:comment ?description} } LIMIT 25
This did not return the query result as I expected it to return the only class
it contained.
Perhaps this clarifies it better. I also tried to simply the query (below) but
no results.
SELECT DISTINCT ?c

?c a owl:Class.

Any suggestions, I'll appreciate.

Re: Fuseki 2.4.0 web user interface
Can you please share the output of the general query? Jjust that we can
see whether the triples have been loaded into a named graph or something
which ta least is not the default graph.

RE: Fuseki 2.4.0 web user interface
Hi Lorenz,
What I meant by Andy's query statement working is that it returned all the 11
triples of my turtle file. His suggested query contained a union of graph
within the SELECT statement.
SELECT * { { ?s ?p ?o } UNION { GRAPH ?g {?s ?p ?o } } }
Next, I tried the OWL version of the same file both in OWL and RDF/XML format
with the query statement:
prefix owl: <http://www.w3.org/2002/07/owl#>
prefix rdfs: <http://www.w3.org/2000/01/rdf-schema#>
SELECT DISTINCT ?class ?label ?description
WHERE {
?class a owl:Class.
OPTIONAL { ?class rdfs:label ?label}
OPTIONAL { ?class rdfs:comment ?description}
}
LIMIT 25
This did not return the query result as I expected it to return the only class
it contained.
Perhaps this clarifies it better. I also tried to simply the query (below) but
no results.
SELECT DISTINCT ?c
WHERE {
?c a owl:Class.
}
Any suggestions, I'll appreciate.
Regards
Mahmood

RE: Fuseki 2.4.0 web user interface
There was no output at all through the general query.
Now I am working with an OWL file and get all the concepts (It has only one
concept). The query I am running is:
prefix owl: <http://www.w3.org/2002/07/owl#>
prefix rdfs: <http://www.w3.org/2000/01/rdf-schema#>
SELECT DISTINCT ?class ?label ?description
WHERE {
?class a owl:Class.
OPTIONAL { ?class rdfs:label ?label}
OPTIONAL { ?class rdfs:comment ?description}
}
LIMIT 25
The OWL file is uploaded successfully but there is no result of the query.
Any thoughts, I'll appreciate.

How are you runnign the server exactly?
Ask this query:

and don't forget to press the "query" button (it caches results otherwise).

Re: Fuseki 2.4.0 web user interface
It is looking for a file called tdb.ttl which is not found. --desc is for a assembler file - you have to provide that, the documentation is out of date.
