Gemini is a very simple-to-use non-intrusive Java framework that seamlessly enables bidirectional relationships between plain old Java objects (POJO). It helps developers to write simpler code to implement rich domain models by eliminating the need to manually check referential integrity and take care of updating the opposite property of a relationship (both simple and container properties). GPL requires your software to also be GPL.
