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
