adding triples in 4store

Question

here url_add is a link that contains the rdf triples that i want to store in 4store.but if i pass url_add as an argument it generates Relative URIerror .

so what is the way in which i can pass url_add as an argument only.

response = store.add_from_uri('url_add')

Traceback (most recent call last):

RelativeURIError: Only absolute URIs are allowed. uri = url_add

What is the value of your URL

It is throwing an exception because you are passing a relative url instead of an absolute (you probably have something like "../../directory/filename.rdf"

If your url is an HTTP url e.g (http://host/filename.rdf) and dereferenceable then you can also use the LOAD directive as part of SPARQL update. So that simply means exectuting a SPARQL query (in the same way you execute a SPARQL query using 4store) using the following expression:

LOAD <http://host/filename.rdf>
INTO GRAPH <http://optional-name-of-graph>
