Re: Deleting the default graph from the TDB
Thank you very much, that was the problem. I did not change so far this default setting in the config file: <#dataset> rdf:type tdb:DatasetTDB ; tdb:location "/var/www/fuseki/tdb" ; tdb:unionDefaultGraph true ; I set it now to false (or better commented out), and now the DROP DEFAULT SPARQL update works as expected.

It works fine, I only had to replace /sparql with /ds/query.

Hi Sandor,
You need to do a federated query. See the SPARQL 1.1 Query spec.
Something like this:
SELECT *
WHERE {

Re: Unsupported major
Dear Andy, I asked it because I tried it in a script that starts Fuseki like that, but it did not work: export JAVA_HOME= /usr/lib/jvm/jre-1.8.0-openjdk.x86_64/bin/java cd /var/www/skosmos/jena-fuseki1-1.3.0 ./fuseki-server --update --mem /ds (I have also tried it with export JAVA_HOME= /usr/lib/jvm/jre-1.8.0-openjdk.x86_64 but it did not work either) How should I use it? export JAVA_HOME= /usr/lib/jvm/jre-1.8.0-openjdk.x86_64/bin/java I have read an issue (JENA-1035), that fuseki-server script ignores JAVA_HOME variable while it executes the "java" command.

Re: extending an existing dataset
Dear Andy, Thank you for your answer. Not quite sure of the setup you have - the "ttl file of the dataset" suggest default graph? I mean the SKOS content in a data file in Turtle format by that. I do not use the default graph, I use individual URIs as graph names for the individual data files that I am going to store in the TDB. I am not sure, but I am afraid that the suggested s-put scrip is not appropriate to upload new data files in my case, since I have already several other data files in the dataset that I want to keep intact. I only would like to replace a certain datafile with a new one under the same graph name or extend it with some additional triplets. As far as I know s-put will clean the entire dataset first before it uploads the new datafile. But I might use s-post, that - according to may knowledge - can add new datafile without cleaning the existing data files from the TDB. Am I right? Another the question is, how can I delete first a dedicated graph from the dataset. The utility s-delete might help, or do I completely misunderstand the work of s-post and s-put? I don't have too much experience in UNIX or Linux, but what should I do directly with wget or curl, that you suggested to see? SPARQL update can be also useful. Could you send me more information or a link about the usage in my case?

Fuseki doesn't allow to upload new datasets
Dear List Members,
I have the following problem:
I have started Fuseki from its base folder (/var/www/fuseki/) without
any problem, but when I want to upload a previously successfully
uploaded file to a named graph or to the default graph I got the error
message:
"Error 404: Not Found
Fuseki - version 1.4.0 (Build date: 2016-05-10T11:59:39+)"
Strange is, that Fuseki doesn't send any reaction to the Upload request.
Last message appeared when I started Fuseki:
"17:00:15 INFO Started 2016/09/02 17:00:15 CEST on port 3030"
I have set the FUSEKI_BASE variable, but it did not help either.
What can be wrong?

Re: question about TDB loader of Jena-Fuseki
Dear Osma,
:-) you did not tell me, that you are also here :-)
But thank you very much for your help again, that was very useful.
I executed, that you suggested, i.e. I have downloaded the full dataset
of the getty aat, and applied the tdbloader of fuseki using the
jena-text-config.ttl file as an assembler file:
/java -cp /fuseki-server.jar tdb.tdbloader --tdb=jena-text-config.ttl
./vocabularies/getty_aat/full/ontology.rdf//
//java -cp /fuseki-server.jar tdb.tdbloader --tdb=jena-text-config.ttl
./vocabularies/getty_aat/full/skos.rdf//
//java -cp /fuseki-server.jar tdb.tdbloader --tdb=jena-text-config.ttl
./vocabularies/getty_aat/full/AATOut_Full.nt//
//java -cp /fuseki-server.jar tdb.tdbloader --tdb=jena-text-config.ttl
./vocabularies/getty_aat/full/AATOut_Contribs.nt//
//java -cp /fuseki-server.jar tdb.tdbloader --tdb=jena-text-config.ttl
./vocabularies/getty_aat/full/AATOut_Sources.nt//
/The files were nicely uploaded to the tdb folder of fuseki.
After starting fuseki with the same ttl file (fuseki-server --config
jena-text-config.ttl), see attached, and run SPARQL queries:
/SELECT (COUNT(*) AS ?count) { //
// GRAPH <http://vocab.getty.edu/aat/> { ?s ?p ?o } //
//} /
to check the number of triples, the result is zero.
I am afraid the problem can be with the graph name (either
<http://vocab.getty.edu/aat/> or default), that I don't know where
should I define.
Best Regards,
Sandor

Dear Sandor,
You can use the same .ttl file that you used for the Fuseki database
and text index configuration, i.e. the one documented here:

Dear Support List,
We are at the University of Vienna developing an archiving system where

therefore we were suggested by the developers of Skosmes to use the tdb
loader to upload the datasete directly to the tdb folder.
We found in the documentation
(https://jena.apache.org/documentation/query/text-query.html#building-a-text-index),
that we can use the
java -cp $FUSEKI_HOME/fuseki-server.jar tdb.tdbloader
--tdb=assembler_file data_file
command, as the TDB loader included with Fuseki, but it is not clear,
*what is going to be the assembler file*. I guess the data_file is the
RDF or NT files, that I am going to upload.
Could anyone explain, or suggest some documentation about this command,
and the details of the assembler_file.
Thank you very much for your help in advance.
Best regards and happy new year,
