dbpedia-extension's Introduction

This project is an extension for Google Refine and provides easy way to add columns from DBpedia to reconciled data (columns).

Data has to be reconciled with DBpedia or SPARQL endpoint, which returns DBpedia resource types.

INSTALL

1. Before installing this extension download Google Refine code from http://code.google.com/p/google-refine/source/checkout. 

2. Pull this extension's code into folder dbpedia-extension under folder /extensions. 
For more information on how to write a Google Refine extensions and where to put the files see http://code.google.com/p/google-refine/wiki/WriteAnExtension

The folder structure should resemble this:
grefine-all/
----------/extensions
--------------/dbpedia-extension
------------------/module
------------------/src
------------------build.xml
------------------README (this file)

3. Update build.xml in folder /extensions with build and clean ant tasks for dbpedia-extension:

<project name="google-refine-extensions" default="build" basedir=".">
    <target name="build">
        <echo message="Building extensions" />
        <ant dir="sample/" target="build" />
        <ant dir="jython/" target="build" />
        <ant dir="freebase/" target="build" />
        <ant dir="gdata/" target="build" />
        <ant dir="dbpedia-extension/" target="build" />
    </target>
    
    <target name="clean">
        <echo message="cleaning extensions" />
        <ant dir="sample/" target="clean" />
        <ant dir="jython/" target="clean" />
        <ant dir="freebase/" target="clean" />
        <ant dir="gdata/" target="clean" />
        <ant dir="dbpedia-extension/" target="clean" />
    </target>
</project>

4. If using Eclipse, make sure that you build project with ant

dbpedia-extension's Issues

DBpedia Countries

For some of the datasets I can see the dbo:Country, but for others I can not see. What is the problem?
I add DBpedia sparql Endpoint with Virtuoso to RDF extension.

installing extension doesn't expose DBpedia choice

I've added this extension to a clone of OpenRefine 2.8 according to the README, and performed an ant build. The console reports "BUILD SUCCESSFUL" but there are two project errors (below) and when I run OpenRefine, access to DBpedia reconciliation is not an option, or evident anywhere I can see. Any ideas?

'The declared package "com.google.refine.tests.model" does not match the expected package "com.google.refine.tests.browsing.facets"'
also
'The declared package "com.google.refine.tests.model" does not match the expected package "com.google.refine.tests.operations.cell"'

HTTP 500 when accessing OpenRefine

Hello,

I tried installing the extension against a clean clone of OpenRefines's git repository, I added the build and clean section to build.xml as instructed, refine starts correctly but when trying to access and page it gives the following

Problem accessing /project. Reason:

I'd fix it myself but I'm a java noob, got any hints?
