Metaschema Java Tools and Libraries

This open-source, Metaschema Java framework offers a set of Java libraries providing a programatic means to work with models defined by the Metaschema modeling language. This framework also supports programatically creating, modifying, parsing, and writing XML, JSON, and YAML instance data that conforms to a given Metaschema model. This work is intended to make it easier for Java software developers to incorporate Metaschema-based capabilities into their applications.

This effort is part of the National Institute of Standards and Technology (NIST) OSCAL Program.

The Metaschema Java framework provides:

• Java objects for loading and working with XML-based Metaschema constructs. This functionality is provided by the Metaschema XML model.
• Java bean code generation based on one or more Metaschema using Maven. This functionality is provided by the Metaschema Maven plugin.
• A Java parser for reading and writing XML, JSON, or YAML into Java beans generated by this framework. This functionality is provided by the Metaschema Java Binding Parser.
• XML and JSON schema generation based on a Metaschema provided by Netaschema Schema Generator.
