RDFBeans framework

RDFBeans is an object-RDF mapping framework for Java. It provides ORM-like databinding functionality for RDF databases ("triplestores") with two basic techniques:

• Classic object persistence: storing and retrieving the state of POJO objects to/from a RDF model

• Dynamic proxy mechanism to access RDF data with Java interfaces mapped directly to the underlying model

RDFBeans is built upon Eclipse RDF4J (Sesame) API to provide object persistence for a number of state-of-the-art RDF triplestore implementations.

RDFBeans is based on Java Annotations mechanism. No special interfaces and superclasses is required, that guarantees minimum modifications of existing codebase and compatibility with other POJO-oriented frameworks.

##Features

• Cascade databinding to reduce development time and ensure referential integrity of complex object models

• Inheritance of RDFBeans annotations from superclasses and/or interfaces

• No external specifications (RDF-schemas) are required: everything is declared by the annotations

• Extensible mechanism of mapping Java types to RDF literals: you can define your own algorithms to represent your data structures with RDF

• Support of basic Java Collections, optionally represented with RDF containers

• Transactions support (triplestore-specific)

• Support of indexed JavaBean properties

• Support of RDF namespaces
