Data Observation Network for Earth (DataONE) is the foundation of new innovative environmental science through a distributed framework and sustainable cyberinfrastructure that meets the needs of science and society for open, persistent, robust, and secure access to well-described and easily discovered Earth observational data
The DataONE Generic Member Node (GMN) is a complete open-source implementation of a DataONE Member Node (MN). As such, it is a data preservation-oriented repository, and one that manages its content collection through the DataONE MN_Storage API. GMN accepts any metadata format, and provides byte-level persistence of objects.
GMN can be used as a standalone Member Node or it can be used for exposing data that is already available by URL. In the latter case, GMN provides a DataONE compatible interface to existing data and does not store the data. Instead it maintains the associated System Metadata, and other DataONE-specific structures.
GMN can also be used as a software starting point or reference for a 3rd party MN implementation.
If an organization wishes to donate storage space to DataONE, GMN can be set up as a replication target.
GMN is built using the Django Framework and utilizes Apache2 as the web server and PostgresSQL as the underlying RDBMS. Other configurations are possible via adaptation.
