tripal

The Tripal package is a suite of Drupal modules for creating biological (genomic, genetic, breeding) websites. Visit the Tripal homepage at http://tripal.info for documentation, support, and other information. The Drupal project page is at http://drupal.org/project/tripal. Maintained by tripal on GitHub, where it has earned 70 stars from the community.

It's actively developed around biological-data, chado, cms-extension, and is a solid reference for anyone building with these tools.
