Hi Al,
Yes, you can use any IRI to name graphs. Thus, in particular you can use
user ids to compose names of graphs.

Hi Daniel,
I am a Newbie at Jena Sparql and I would like to know how you addressed the value of each Named Graph you created, for
example, I have successfully used GRAPH qm:g1 to create a Named Graph "g1", can I substitute a variable for
"g1" such as "user _number", to create multiple Named Graphs based on the value of "user
_number"?
Thank you for help...

Hi Chris,
It is possible. In fact, I have loaded 57 million of named graphs and
then queried without problem. You can see the details in

Hi All,
How many named graphs can Jena gracefully handle? Hundreds, thousands,
millions? I've found references to Jena handling large triple stores,
with billions of statements; but nothing about how many named graphs.
I'm writing a system where I'm considering giving each remote client
its own named graph where it uploads data. I'm further considering
keeping historical data, so the client would get a new named graph
each time it sent its data. I'm curious if this is a bad idea.
