Hi everybody,

I am using the LOD 1.5.12 version, along with the RapidMiner Studio 7.1.0. version. I have some triples stored in a private Virtuoso Open Source Server 07.20.3217.

I use the “SPARQL Data Importer” Operator in order to make SPARQL queries to this endpoint, and retrieve some information. My problem is that, even though I make changes on the triples, the SPARQL Data Importer does not retrieve the updated triples. Therefore, I have to change the query (for example, I change the number in the LIMIT clause of the query) in order to obtain the obtained triples.

It seems the SPARQL query results is stored in some kind of cache. I couldn’t find any parameter or similar to deactivate this option.

Is anyone having similar issues?

Thanks in advance.

Best regards,

Iker Esnaola-Gonzalez

Hi,

I haven't really tested the extension in RM 7, but you can try to deactivate the cache in the options of the extension.

Cheers,

Petar
