[Mulgara-general] Query from restricted graphs

[Ben Hysell]

Alex,

The try this:

select $g from <rmi://192.168.0.1/server1#sampledata> where $g
<dc:title> 'test graph';

If you navigate to http://192.168.0.1:8080 on your test machine the help
pages for Mulgara will be visible...try 'iTQL Commands' on the left hand
side of the page for structuring queries.

Subject: [Mulgara-general] Query from restricted graphs

Hi all,

I'm currently trying mulgura (never used kowari before), and got a
question regarding 'from' queries.

I'd like to retrieve information from a set of statements constraint
with their properties.

I first add all needed statements:

create <rmi://192.168.0.1/server1#sampledata>;
load <http://apassant.net/blog/sioc.php?type=post&id=104>
into<rmi://192.168.0.1/server1#sampledata>;
insert <http://apassant.net/blog/sioc.php?type=post&id=104> <dc:title>
'test graph' into <rmi://192.168.0.1/server1#sampledata>;

I'm looking for something like

select $s $p $o from $g where $s $p $o and $g <dc:title> 'test graph';
(leads to Query Error: [1,22] expecting: '(', resource )

Is there a way to do such queries ?

Finally, is there any difference between from and in ?

Thanks for your help,

Alex.
