DDMSence (pronounced "dee-dee-em-Essence") is a Java API that supports the DoD Discovery Metadata Specification (DDMS). It provides a complete implementation of the DDMS specification using DDMS 2.0, 3.0, 3.1, 4.0.1, or 4.1. Validation is performed according to both the schema and the specification, and custom validation rules can be defined with ISO Schematron.
This release adds full support for DDMS 4.1. It is backwards-compatible with v2.0.0.
