| <hr/> |
| <p class="col-sm-12 breathing-space"> |
| A distributed parallelized ( Map Reduce) wrapper around <a href="https://creadur.apache.org/rat/">APACHE RAT<sup>TM</sup> (Release Audit Tool)</a> that <br/> goes far beyond RAT<sup>TM</sup> by leveraging <a href="http://oodt.apache.org/">Apache OODT<sup>TM</sup></a> to dramatically speed up the process. |

| <h4>Scales to large code bases</h4> |
| <p>DRAT is a Map Reduce version of RAT using <a href="http://tika.apache.org/">Apache Tika</a> to automatically sort and classify the code base files</p> |
| </div> |
| <div class="offset-md-1 col-md-3 breathing-space"> |
| <i class="fa fa-object-group fa-3x fa-color" aria-hidden="true"></i> |
| <h4>Mapreduce for the win!</h4> |
| <p>DRAT uses <a href="http://oodt.apache.org/">Apache OODT</a> to index metadata and Tika information about those code files into <a href="https://lucene.apache.org/solr/">Apache Solr</a> and OODT to produce a Map Reduce workflow</p> |
| </div> |
| <div class="offset-md-1 col-md-3 breathing-space"> |
| <i class="fa fa-tasks fa-3x fa-color" aria-hidden="true"></i> |
| <h4>Incremental output</h4> |
| <p>DRAT runs RAT incrementally on k-sized chunks of same-MIME-typed files (detected by Tika) and then producing incremental, per type logs, and then aggregating and reducing them into a combined log at the end.</p> |
