Sergio Fernández commented on MARMOTTA-426:
-------------------------------------------
Rob is right, SPARQL 1.1 introduced different query parameters for query and
update operations. Further details at:
* http://www.w3.org/TR/sparql11-protocol/#query-operation
* http://www.w3.org/TR/sparql11-protocol/#update-operation
But... what Marmotta currently does out of the standard is to check for the
'query' parameter if the 'update' is missing, in a way to allow the transition
to legacy clients. But such feature could removed at any moment. So, please,
*do not use it* if you are aware of the protocol change.

> Key: MARMOTTA-426
> URL: https://issues.apache.org/jira/browse/MARMOTTA-426
> Project: Marmotta
> Issue Type: Bug
> Components: Platform, Web Services
> Affects Versions: 3.1-incubating
> Reporter: Francis De Brabandere
> Assignee: Sebastian Schaffert
> Labels: sparql, update
> Fix For: 3.2
>
>
> According to the 1.1 Sparql protocol spec table at:
> http://www.w3.org/TR/sparql11-protocol/#query-operation
> A urlencoded post should use the "query" parameter for the query, currently
> marmotta seems to be using the "update" parameter which is wrong.
> This causes the user to get a 400 reponse saying with the (currently
> confusing) message "no SPARQL query specified"
> Test that reproduces this below:
> {code:java}
> @Test
> public void testUpdate() throws IOException, InterruptedException {
> String insert =
> "PREFIX dc: <http://purl.org/dc/elements/1.1/>\n" +
> "INSERT DATA { <http://example/egbook3> dc:title \"This is an
> example title\" }";
> expect().
> log().ifError().
> statusCode(200).
> given().
> contentType("application/x-www-form-urlencoded").
> header("Accept", "application/xml").
> formParameter("query", insert).
> when().
> post("/sparql/update");
> }
> {code}
