Subject DRAT is now scanning Apache SVN code base!
Date Sun, 31 Jan 2016 20:52:20 GMT
Hello Everyone,

With great pleasure, I would like to introduce DRAT (Distributed Release
Audit Tool) which is a distributed, parallelized wrapper around Apache RAT
to inspect for appropriate open source licensing in software projects.
DRAT was started by my advisor, Chris Mattmann, in an effort to get RAT
working on a ver large code base. RAT uses Apache OODT, Apache Tika, and
Apache Solr.

We are now auditing the complete Apache SVN code base to check for proper
licenses. Until now, we have scanned 171 / 191 repositories and
illustrated the statistics for 133 of them through D3 visualization
located at

Projects should check out the MIME analysis of the code base and click
around. Please also note due to the sheer size of the Apache code bases
and the fact that we scanned and included all revisions in the Apache SVN
repo, DRAT is not running in real time. We are running DRAT on the NSF
Super Computer Wrangler, which has a petabyte of flash storage and the
ability to stand up Hadoop and Spark clusters. We are also working on a
paper describing our results.

Please send feedback to myself (Karanjeet Singh <>),
Professor Mattmann <> and/or

Thanks & Regards,
