Metacat

DataONE Configuration

~~~~~~~~~~~~~~~~~~~~~

Metacat can be configured to operate as a Member Node within the DataONE

federation of data repositories.  See :doc:`dataone` for background and details

on DataONE and details about configuring Metacat to act as a DataONE Member Node.

Replication Configuration

~~~~~~~~~~~~~~~~~~~~~~~~~

Metacat can be configured to replicate its metadata and/or data content to another

Metacat instance for backup and redundancy purposes, as well as to share data across

sites.  This feature has been used to create the Knowledge Network for Biocomplexity

(KNB), as well as other networks.  See :doc:`replication` for details on

the replication system and how to configure Metacat to replicate with another node.

.. Note:: 

  Note that much of the functionality provided by the replication subsystem in Metacat

  has now been generalized and standardized by DataONE, so consider utilizing the

  DataONE services for replication as it is a more general and standardized approach

  than this Metacat-specific replication system.  The Metacat replication system

  will be supported for a while longer, but will likely be deprecated in a future

  release in favor of using the DataONE replication approach.
