Re: [easyrdf] DELETE/INSERT

[Nicholas Humfrey]

Hello,

I'm afraid that EasyRdf does not currently support SPARQL 1.1 Update at the moment but it is on the todo list:

https://github.com/njh/easyrdf/issues/66

However it does support the SPARQL 1.1 HTTP GraphStore protocol:

http://www.w3.org/TR/sparql11-http-rdf-update/

Sorry I didn't reply to your email sooner.

From your other email, it looks like you have worked out what to do.

Hi,

I can't run insert query which includes "inserting literal". Can you give me an example which can insert a literal with EasyRdf_SPARQL_Update.php

thx.

Hello,

Sorry for the delay in replying. I was struggling to get Google Groups to release the message - seems to be working now.

I'm afraid that I have not had a chance to merge in EasyRdf_SPARQL_Update.php yet.

I plan to add support for it in the next release.


Maybe Mochamad can help you in the meantime?

Hello,

I have added an update() method to EasyRdf_Sparql_Client:
https://github.com/njh/easyrdf/blob/master/lib/EasyRdf/Sparql/Client.php#L143

Which you can use to execute any SPARQL 1.1 Update query on a store that supports it.

Would be interested in any feedback - in particular if you think that query() and update() should be throwing exceptions for failed querys, and what you think the return type should be for a successful update().

Next I will be adding insert() and delete() methods...

Consistency with SQL operations makes sense to lurker me, so returned
values might consist of an integer count of the number of instances
affected, possibly zero. -AS

[Nicholas Humfrey]

Unfortunately the SPARQL protocol does not make that information available.

Usually all you get back is the HTTP status code:

http://www.w3.org/TR/2013/REC-sparql11-protocol-20130321/#update-success

I suspect I should therefore return a EasyRdf_Http_Response object.

The alternative is to return true/false, but that is probably less useful.

This one work , in order to get it work we must do :
1. Insert this class into the EasyRDF

2. Load this class with include_once on EasyRDF.php 

3. Call the class

Hello Todi,

There is now update support in the master branch.

Example using local Fuseki instance:

$client = new EasyRdf_Sparql_Client(
'http://localhost:3030/ds/query',
'http://localhost:3030/ds/update'
);

$client->update('INSERT DATA { <s> <p> <o> }');

Ahh cool, so fast :) just gonna fork the master. Please give the example file too. An Insert / Delete command example will be great, tutorial are  rarely found on the net. :) Congrats anyway :) 

[Nicholas Humfrey]

Yup, will be creating an example :)

They are my preferred way of learning how things work.
