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.
- Provides a complete implementation of the DDMS specification using any version of DDMS between 2.0 and 5.0, suitable for several use cases.
- Java object model can be created from existing XML files, or built up from scratch with basic Java data types. Components automatically transform into well-formed XML, HTML, JSON, and Text output.
- Validates assertions against the complete specification, not just the XML schemas. Integrated with the Controlled Vocabulary Enumerations for ISM attributes, as defined by the Intelligence Community, and supports Schematron-based custom validation rules.
- Three sample applications and accompanying tutorials provide an introduction to the library, and Power Tips are available for more experienced users.
DDMSence comes with a complete set of JUnit tests, and is released under the GNU Lesser General Public License (LGPL).
