These Java libraries provide a set of Java models and APIs, which provide a unified approach to the creation and processing of library metadata objects.

• A corresponding Java object model was derived for each standard.
• JAXB annotations (Java API for XML-Binding) are used with XML-based standards to specify the mapping between the Java object model and it‘s XML representation.
• The JSON Binding API is used for the serialization and deserialization of metadata objects in JSON-based standards.
• Validator classes are used to check XML data against the corresponding XML Schemas.

The Wiki contains some code examples on How to use the APIs.
