HashStore is a server-side java library implementing a content-based identifier file system for storing and accessing data and metadata for DataONE services. The package is used in DataONE system components that need direct, filesystem-based access to data objects, their system metadata, and extended metadata about the objects. This package is a core component of the DataONE federation, and supports large-scale object storage for a variety of repositories, including the KNB Data Repository, the NSF Arctic Data Center, the DataONE search service, and other repositories.
DataONE in general, and HashStore in particular, are open source, community projects. We welcome contributions in many forms, including code, graphics, documentation, bug reports, testing, etc. Use the DataONE discussions to discuss these contributions with us.
Documentation is a work in progress, and can be found on the Metacat repository as part of the storage redesign planning. Future updates will include documentation here as the package matures.
HashStore is a Java package, and built using the Maven build tool.
To install hashstore locally, install Java and Maven on your local machine,
and then install or build the package with mvn install or mvn package, respectively.
We also maintain a parallel Python-based version of HashStore.
