HTTP ERROR 500 when initializing Open Refine with RDF extension

[Miquel Centelles]

Hi,

When I try to initialize OpenRefine including RDF extension an error message displays saying:

HTTP ERROR 500

Problem accessing /. Reason:

    Butterfly Error

Butterfly incurred in the following errors while initializing:

Any tips to solve it?

Thank you very much.

Hi Miguel,

Are you using one of the RDF extensions I pointed to recently?

It looks like you are currently using Google Refine 2.5. I'd suggest trying the same extension with OpenRefine 2.6 (probably 'release candidate 2' ) and see if that works

Hi Miquel (and apologies for getting your name wrong in my last reply - autocorrect!)

I've now found a link to the last 'official' release of the RDF extension by DERI. You can download this from https://github.com/fadmaa/grefine-rdf-extension/downloads - it is the 0.8.0 version - you could try this with Google Refine 2.5 and see if that works.

Hi Owen,

It's all OK; thank you very much. I'm going to try it through https://github.com/fadmaa/grefine-rdf-extension/downloads

I'll report obout it.

Hi Owen and all,

I tried both options -Google Refine 2.5 + RDF extension 0.8 and OpenRefine 2.6 + RDF extension 0.9- and them all work.

Thanks!
