Re: Fuseki / Java

[Lorenz Buehmann]

1. What is the backend of your Fuseki server?

2. You can use RDFConnection [1] to "communicate" with the Fuseki if
there is no underlying TDB

 For example to create Activity I use this method :

 Resource res = onto.getIndividual(uri);

 res = onto.createResource(uri);

 Now I need to use Fuseki server to save all modification that I do ,

 I know how to connect to Fuseki server , but I don’t found how I can

 using (my code + Fuseki server ).


 thanks for your help

Re: Fuseki / Java

[Lorenz Buehmann]

To extend my answer, for SPARQL I'd prefer the RDFConnection way [1]

Fixed (in staging).


But that URL doesn't lead to anything.

I'm curious as to what, if anything, that ought to point to.  I'm not
even sure what it means to say "use Fuseki from Java" other than just
using something like HTTPClient to interface with the Fuseki HTTP
services.  Is there more I should know about, or is that pretty much
it?


Thanks,

From Java,

http://jena.apache.org/documentation/rdfconnection/

This pulls together the different SPARQL protocol APIs (query, update, 
GSP) into one thing and provides for a uniformity between local and 
remote.


That's not the same as making remote look like local. The unit of work 
is no longer an individual statement in a model for remote.


In addition to the command line tools mentioned, there is also the SOH 
scripts:

Re: Fuseki java client?

[ajs6f]

That's correct-- Fuseki's whole purpose is to implement those HTTP APIs.

Thanks Jean-Marc.  Is it safe to assume those are just implemented in
terms of the same http operations used by the s-* commands that ship
with Fuseki?  That is, there isn't another special protocol for Java
clients or anything is there?
