-HashStore is a server-side python package 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](https://dataone.org), and supports large-scale object storage for a variety of repositories, including the [KNB Data Repository](http://knb.ecoinformatics.org), the [NSF Arctic Data Center](https://arcticdata.io/catalog/), the [DataONE search service](https://search.dataone.org), and other repositories.

 ## HashStore Overview
 
-HashStore is a content-addressable file management system that utilizes the content identifier of an object to address files. The system stores objects, references (refs) and metadata in its respective directories and provides an API for interacting with the store. HashStore storage classes (like `FileHashStore`) must implement the HashStore interface to ensure the expected usage of HashStore.
