When this box is unchecked, the DataONE Coordinating Nodes will not attempt to synchronize at all, but when checked, then DataONE will periodically contact the node to synchronize all metadata content. To be part of the DataONE network, this box must be checked as that allows DataONE to receive a copy of the metadata associated with each object in the Metacat system. The switch is provided for those rare cases when a node needs to be disconnected from DataONE for maintenance or service outages. When the box is checked, DataONE contacts the node using the schedule provided in the ``Synchronization Schedule`` fields. The example in the dialog above has synchronization occurring once every third minutes at the 10 second mark of those minutes. The syntax for these schedules follows the Quartz Crontab Entry syntax, which provides for many flexible schedule configurations. If the administrator desires a less frequent schedule, such as daily, that can be configured by changing the ``*`` in the ``Hours`` field to be a concrete hour (such as ``11``) and the ``Minutes`` field to a concrete value like``15``, which would change the schedule to synchronize at 11:15 am daily.hIj}hJhKhLhhhN}r (hP]hQ]hR]hS]hU]uhWK·hXhhC]r (haXThe r …r}r(hHXThe hIj ubj )r}r(hHX``Enable DataONE Services``hN}r(hP]hQ]hR]hS]hU]uhIj hC]rhaXEnable DataONE Servicesr…r}r(hHUhIjubahLj¨ubhaX· checkbox allows the administrator to decide whether to turn on synchronization with the DataONE network.

We encourage people to allow replication to their nodes, as this increases the scalability and flexibility of the network overall. The three "Default" fields set the default values for the replication policies for data and metadata on this node that are generated when System Metadata is not available for an object (such as when it originates from a client that is not DataONE compliant). The ``Default Number of Replicas`` determines how many replica copies of the object should be stored on other Member Nodes. A value of 0 or less indicates that no replicas should be stored. In addition, you can specify a list of nodes that are either preferred for use when choosing replica nodes, or that are blocked from use as replica nodes. This allows Member Nodes to set up bidirectional agreements with partner nodes to replicate data across their sites.

DataONE has devised a simple but effective access control system that is compatible with the prior system in Metacat. For each object in the DataONE system (including data objects, scientific metadata objects, and resource maps), a SystemMetadata_ document describes the critical metadata needed to manage that object in the system. This metadata includes a ``RightsHolder`` field and an ``AuthoritativeMemberNode`` field that are used to list the people and node that have ultimate control over the disposition of the object. In addition, a separate AccessPolicy_ can be included in the ``SystemMetadata`` for the object. This ``AccessPolicy`` consists of a set of rules that grant additional permissions to other people, groups, and systems in DataONE. For example, for one data file, two users (Alice and Bob) may be able make changes to the object, and the general public may be allowed to read the object. In the absence of explicit rules extending these permissions, Metacat enforces the rule that only the ``RightsHolder`` and ``AuthoritativeMemberNode`` have rights to the object, and that the Coordinating Node can manage ``SystemMetadata`` for the object.
