insert
Inserts statements into a model. Specify the statements either explicitly or by using a select
command. The corresponding command for deleting statements is delete
.
To insert a single statement, specify its subject, predicate and object after the insert
command. For example:
insert <ns:subject> <ns:predicate> 'object' into <rmi://mysite.com/server1#model>;
To insert multiple statements, repeat the statements one after the other. For example:
insert <ns:subject> <ns:predicate> 'object'
<ns:subject2> <ns:predicate2> 'object2' into <rmi://mysite.com/server1#model>;
Note - Inserting multiple statements using a single insert
command provides optimal performance when working over a network.
Blank (anonymous) nodes are inserted using unbound variables. For example:
insert <ns:subject> <ns:predicate> $node
$node <ns:predicate2> 'object2' into <rmi://mysite.com/server1#model> ;
Where $node
becomes an anonymous node at execution time.
An alternative way to insert a group of statements is to include a select
command after the insert
command. The query must select exactly three columns, corresponding to the subject, predicate and object (in that order) of the statements to be added.
The following example selects all the statements in #model1
and uses the result within an insert
command to copy all the statements in #model1
to another model, #model2
.
insert select $s $p $o from <rmi://mysite.com/server1#model1>
where $s $p $o into <rmi://mysite.com/server1#model2>;
Note - The query must return valid RDF statements. That is, the subject and predicate must be resources, not literals.
