Hi Andy - thank you for answer
my point is that
./s-get http://localhost:3030/ds/data http://semweb.ch/SEMWEB
./s-query --service http://localhost:3030/ds/query 'SELECT * from
<http://semweb.ch/SEMWEB> {?s ?p ?o}'
For which setup --mem or --loc?
is functioning at command line level while
SELECT * from <http://semweb.ch/SEMWEB> {?s ?p ?o}
and
SELECT * {GRAPH <http://semweb.ch/SEMWEB> {?s ?p ?o}}
are ***NOT*** functioning inside the SPARQLer - General purpose processor
with error "Error 400: No dataset description in protocol request or in
the query string"
The general purpose processor does not have any data behind it.
FROM will try to do a HTTP GET on http://semweb.ch/SEMWEB, which will
fail with a 404.
"""
Error 400: Failed to load URL http://semweb.ch/SEMWEB
"""
The GRAPH version will have no data to query.
It is not connected to the data you loaded in /ds.
To query your loaded data in /ds go:
"Control panel" -> pick /ds -> use the query form.
Although same repository ...
Furthermore
./s-get http://localhost:3030/ds/data http://semweb.ch/SEMWEB ./s-query
--service http://localhost:3030/ds/query 'SELECT * { GRAPH
<http://semweb.ch/SEMWEB> {?s ?p ?o}}'
gives an error "`cmd_soh': invalid option: --service
(OptionParser::InvalidOption)
from ./s-get:703:in `<main>'"
Different and unrelated - you have all the commands one line so the
s-get is seeing the --service from s-query.
So we still have the issue...
Any ideas ?
Andy
Thank you in advance :)

Dear Jena community
I am starting to use the Jena framework but before I am installing/using
the fuseki RDF server.
I could start and run it properly but with some peculiarities:
1. When started with the mem option (in memory) and some RDF data is
loaded into a graph (no default graph) the only command that runs well
is the s-get with the graph again: All the RDF statements are returned.
The s-query --service is not running - nothing returned. And in the
webconsole http://localhost:3030/sparql.html none of my graphs are
loadable, neither per from <graph> nor by the apposite field "Target
Graph URI". Why is this so? Is there a bug in the fuseki server?
Here my operations:
./s-put http://localhost:3030/ds/data http://semweb.ch/SEMWEB
/Users/fabio/Documents/DATA/thesauri/pp_project_semweb.ttl
That puts data into named graph http://semweb.ch/SEMWEB.
./s-get http://localhost:3030/ds/data http://semweb.ch/SEMWEB
./s-query --service http://localhost:3030/ds/query 'SELECT * from
<http://semweb.ch/SEMWEB> {?s ?p ?o}'
To access a named graph, use GRAPH. FROM on a general dataset tries
to load it from the web. Did the fuskei log say anything about not
being able to load it?
Try:
SELECT * { GRAPH <http://semweb.ch/SEMWEB> { ?s ?p ?o} }'
2. I restarted the fuseki server with "./fuseki-server --update
--loc=./RDFDATA /ds" and noticed that all three of the commands ran
well:
./s-put http://localhost:3030/ds/data http://semweb.ch/SEMWEB
/Users/fabio/Documents/DATA/thesauri/pp_project_semweb.ttl
./s-get http://localhost:3030/ds/data http://semweb.ch/SEMWEB
./s-query --service http://localhost:3030/ds/query 'SELECT * from
<http://semweb.ch/SEMWEB> {?s ?p ?o}'
For TDB, FROM picks out a graph from the dataset, not the whole web.
TDB can't load from the web for a temporary dataset just for the query
so the mechanism is overloaded. See the thread with Willie Minor.
Again. GRAPH is the way to access the named graph. Or
--set tdb:unionDefaultGraph=true
to make the default graph for query the computed union of all the
named graphs.
still the web console "SPARQLer" "could not load" the graph
"http://semweb.ch/SEMWEB";
I'd expect hat from the in-memory dataset but not with TDB. Testing
here, I don't see that with --loc -- I see some query results.
Andy
What is wrong in what I am doing?
Thank you for your advice
