Fuseki does support loading FROM URLs from the web in the "main" version
of Fuseki. If the service is backed by a dataset it will use the graphs
from the dataset but there is the "general" query service as well.
It is --general in Fuseki.main and that is what
http://www.sparql.org/sparql.html
is using.
Andreas - were you looking for it in the webapp version?

Hi ajs6f,
yes, what I am aiming for is what the FROM statement would do if it could
target graphs outside my own dataset.
The only thing I have come up with so far - as an idea, not tested - is
loading the RDF file into a named graph, querying it and then dropping it
again. What I am asking is whether there is a simpler way of instructing
Fuseki to temporarily load that graph just for the purposes of one query.
Best,
Andreas

Betreff: Re: Using FROM on external RDF files in Fuseki
I'm not quite sure what you are asking about here: Do you mean to query
both a new graph and the main dataset at the same time, and to do that
without using anything other than SPARQL, and without loading the new graph
into your dataset?

Dear all,
after trying for a while, I found out that Fuseki does not temporarily
add external RDF files to the default graph when they are included through
a FROM statement in the SPARQL query, which was also confirmed on
StackExchange [1].
Since this option isn't available, is there a good way of querying an
external RDF file without permanently adding it to the graph by loading it?
For example, my own graph might contain a link to an RDF file like [2], and
I want to query that file from my application (through Fuseki), but not
store it in my own triple store.
Any help and/or advice would be welcome,
Andreas
