Dryad is a repository for data underlying scientific publications, with an initial focus on evolutionary biology and related fields. Dryad allows investigators to validate published findings, explore new analysis methodologies, repurpose the data for research questions unanticipated by the original authors, and perform synthetic studies such as formal meta-analyses.

The core code of Dryad comes from the DSpace repository software. Developers using the Dryad code should first familiarize themselves with DSpace.

Documentation specific to the Dryad codebase can be found in the Dryad GoogleCode wiki and the docs directory. More background about Dryad and current development projects is available in the Dryad wiki.
