fuseki doesn't load jena TDB data
Hi,
i have some problem with jena TDB and fuseki.
i created a store with jena TDB (version 0.0.8). that action create a folder which contains a knowloedge base.
i wanted to load the kwnowledge base from the folder on fuseki server (version 1.1.0).but fuseki is creating a new jena TDB store which is empty; it doesn't load my knowledge base.
here is the command i used to launch fuseki server on my jena TDB store :
fuseki-server --loc=C:/tdbFolder /DatasetPathName
for get data from fuseki server i used the command :http://localhost:3030/DatasetPathName/data?default
thanks you for your help.
Reegards,
Barry

thanks you Andy for your help. i used the SPARQL Query to acced to the dataset becausethe three first solution not worked. i don't know why.

Barry

Re: fuseki doesn't load jena TDB data

You seem to have loaded the data using relative URIs for the graph name.
URIs should be absolute (e.g. http://server/path)
The data?graph= operation retrieves by absolute URI only.
You only have one named graph so either
1/ Load the data into the default graph, use .../data?default
2/ Run with unionDefaultGraph on and use .../data?default
3/ Load the data with an absolute URI.
4/ Use a SPARQL Query
CONSTRUCT {?s ?p ?o }
WHERE { GRAPH ?g { ?s ?p ?o } }
which is exploiting your setup (or what I think it is).

Hi,
when i try this url : http://localhost:3030/DatasetPathName/data?graph=RoyalCanin-Audit
fuseki give this error :
11:37:07 INFO [15] GET http://localhost:3030/DatasetPathName/data?graph=RoyalCanin-Audit11:37:07 INFO [15] 404 No such graph: <http://localhost:3030/DatasetPathName/data/RoyalCanin-Audit> (1 ms)
or when i execute this request : SELECT * { GRAPH ?g {} }the result is : ----------------------
| g |
======================
| <RoyalCanin-Audit> |
----------------------
so the datasett exist but fuseki return 404 error.
can someone tell why i have 404 error please?

Barry

fuseki give this error :

or when i execute this request : SELECT * { GRAPH ?g {} }the result is : ----------------------

so the datasett exist but fuseki return 404 error.

http://localhost:3030/DatasetPathName/data?default only returns the data
in the default graph. From the sounds of things you have your data in
named graphs so the default graph would be empty
If you want to get the data from a specific graph use the following URL:
http://localhost:3030/DatasetPathName/data?graph=GraphName

Hi Andy,
when i access to this url : http://localhost:3030/DatasetPathName/data?default fuseki said
10:10:21 INFO [5] GET http://localhost:3030/DatasetPathName/data?default10:10:21 INFO [5] 200 OK (1 ms)
but i have no data.
when i execute the query SELECT * { GRAPH ?g {} }, it return the name of the dataset : royalCanin.
may be fuseki can see the dataset but i use wrong way to access data,is there another way to get dataset data using url without using http://localhost:3030/DatasetPathName/data?default?
thank u for your help
