title: Tool to pre-process .rdf for GraphDB workbench import?
body: <p>I have a .rdf file (over 2gb compressed) that apparently has some duplicated IRIs in the middle, and perhaps other issues.</p>
  <p>The following error in the workbench during import:</p>
  <pre><code>  RDF Parse Error: ID '_D5C2483C53D3F747_up.name_uORF' has already been defined [line 6907110, column 53
  </code></pre>
  <p>Is there a tool to pre-process these huge files prior to import using some defined behavior, eg &quot;just skip it&quot;, etc?</p>
