Openlims

There are several commercial Laboratory Information Management Systems out there. My current employer recently purchased one of these for a very large amount of money. This product is less than spectacular, in fact even if it was free I would not recommend anyone ever use it.
After unsuccessfully searching for an acceptable open source alternative I decided to start working on Openlims. Most LIMS products support a set of standard features: log samples, assign tests, log results and generate reports. Customization of these features is very important, Openlims achieves this by providing a Java API that can be used to extend the generic types defined in Openlims. Openlims uses reflections to instantiate user defined types and uses properties to persist values that extend the generic types.
Persistence is handled by Hibernate, logging and auditing with AspectJ and the Dojo Spreadsheet Widget for data entry. Openlims also defines several aspects that can be extended to further customize the way data is persisted and displayed.
This project is still in the design and prototyping phase, and there is no website yet. I would like more input from the community on features and tools.
