A simple and elegant approach to dealing with bitemporal issues in rich domain models.
The code in this project provides a simple and elegant approach to dealing with bitemporal issues in rich domain models. While the user (application) level API is fluent and straightforward, it also provides you with full access to temporal information when required. Furthermore, you can still persist your core domain objects, and their bitemporal properties using a capable ORM product such as Hibernate.
At this moment, this code is not part of a real project, and as such it is not actively worked on or developed. Still, it provides a good starting point for those that need to tackle temporal issues in their applications.

Java 8 (JDK 1.8) or later is required to build and use the code in this project. ThreeTen Extra (http://www.threeten.org/threeten-extra/) is used internally, and is the only external dependency.
Note that a Java 5 compatible version is available in the bitemporal-java5 branch.
The project is packaged as a simple Maven project (http://maven.apache.org/). Simply executing 'mvn package' in the project directory will build the project and package it as a jar file.

The slide deck for the "Temporal Issues in a Rich Domain Model" session presented by Erwin Vervaet at The Spring Experience 2007 is included in the 'doc/' directory. These slides document the code in this project and provide a general introduction to dealing with temporal issues in rich domain models. The included unit tests also demonstrate usage of the code.
