Europeana java Client library (formerly europeana4j)
The java client library allows the functionality of the Europeana API to be integrated into an Eclipse workspace and develop software applications incorporating the Europeana API.
The original europeana4j project can be found here. The library provides a clean Java interface to the Europeana Search API, with JavaBeans encapsulation, transparent pagination of results and utilities to copy and verify thumbnails.
