Our platform
Dryad is an open source, community driven project that takes a unique approach to data publication and digital preservation. Dryad focuses on search, presentation, and discovery and delegates the responsibility for the data preservation function to the underlying repository with which it is integrated.
For information about submission to Dryad, see our guidance here.
Architecture and implementation
Dryad is completely open source. Our code is made publicly available on GitHub. Dryad is based on an underlying Ruby-on-Rails data publication platform called Stash. Stash encompasses three main functional components: Store, Harvest, and Share.
- Store: The Store component is responsible for the selection of datasets; their description in terms of configurable metadata schemas, including specification of ORCID and Fundref identifiers for researcher and funder disambiguation; the assignment of DOIs for stable citation and retrieval; designation of an optional limited time embargo; and packaging and submission to the integrated repository
- Harvest: The Harvest component is responsible for retrieval of descriptive metadata from that repository for inclusion into a Solr search index
- Share: The Share component, based on GeoBlacklight, is responsible for the faceted search and browse interface
Individual dataset landing pages are formatted as an online version of a data paper, presenting all appropriate descriptive and administrative metadata in a form that can be downloaded as an individual PDF file, or as part of the complete dataset download package, incorporating all data files for all versions.
To facilitate flexible configuration and future enhancement, all support for the various external service providers and repository protocols are fully encapsulated into pluggable modules. Metadata modules are available for the DataCitemetadata schema. Protocol modules are available for the SWORD 2.0 deposit protocol and the OAI-PMH and ResourceSync harvesting protocols. Authentication modules are available for InCommon/Shibboleth18 and ORCID identity providers (IdPs).
We welcome collaborations to develop additional modules for additional metadata schemas and repository protocols. Please email the Dryad help desk or visit GitHub for more information.

History
Dryad's original iteration launched in 2009 and was built upon the open-source DSpace repository software. In 2019, Dryad merged with Dash, a data publication service developed at the University of California Curation Center (UC3), a program at California Digital Library (CDL).
