DDMSence v2.6.0

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).
