'''Java Model Railroad Interface''' (JMRI) is an [[Open-source software|open source program]] for model railroad hobbyists, released under [[GNU General Public License]] v2. It allows users to control LED lights, horn, or switch the railway of hobbyist open-source or commercials closed-sourced trains.<br />
<br />
JMRI is a suite of tools distributed via a single [[download]]. The two most popular tools are DecoderPro for programming [[Digital Command Control]] (DCC) decoders, and PanelPro for controlling layouts.<br />
<br />
== History ==<br />
Starting in 2005, JMRI's project administrator, Bob Jacobsen, was involved in a [[Jacobsen v. Katzer|legal dispute]] with Matt Katzer in the [[United States District Court for the Northern District of California]]. Significantly, the [[United States Court of Appeals for the Federal Circuit]] ruled that infringing on the copyright of open source software by violating its license terms could result in monetary damages.<ref name="appealsCourtFinding">{{cite web|url=http://www.cafc.uscourts.gov/opinions/08-1001.pdf |title=Appeal from the U.S. District Court for the Northern District of California |access-date=2009-10-03 |url-status=dead |archiveurl=https://web.archive.org/web/20090827060538/http://www.cafc.uscourts.gov/opinions/08-1001.pdf |archivedate=August 27, 2009 }}</ref> The case was settled in early 2010.<ref name="settle">[http://www.consortiuminfo.org/standardsblog/article.php?story=201002190850472].
