DDMSence (pronounced "dee-dee-em-Essence") is the only open-source Java library that fully supports the DoD Discovery Metadata Specification (DDMS). It converts DDMS Resources (also called assertions or metacards) into a Java object model, allowing them to be manipulated or traversed within the context of a Java environment.
DDMSence comes with a complete set of JUnit tests, and is released under the GNU Lesser General Public License (LGPL).
Brian Uri! is a Technical Lead at Novetta Solutions in Reston, Virginia. He has been involved with DISA's enterprise services and data strategy efforts (including DDMS, Universal Core, the Data Services Environment, Enterprise Service Monitoring and Strategic Knowledge Integration Web) since the inception of the Net-Centric Enterprise Services (NCES) program in 2005.
DDMSence was conceived in January 2010 and grew out of Brian's desire to gain more practical XML Schema experience, to write something useful which had never been done before, and an unusually large amount of free time.
