+Connection Batch Import
+==============
+
+Administrators may batch import connections and connection groups from a file,
+if the underlying authentication module supports dynamic connection/group creation.
+To start a batch import, click the "Import" button on the connection edit tab.
+
+![Link to Batch Import](images/batch-import-admin-link.png)
+
+At this point, the interface will accept a CSV, JSON, or YAML file containing
+a list of connections to be imported.
+
+![Batch Import Start](images/batch-import-start.png)
+
+(batch-import-success)=
+Success
+-----------------
+
+On success, the batch import UI will simply display a message indicating
+how many connections were imported.
+
+![Batch Import Success](images/batch-import-success.png)
+
+(batch-import-failure)=
+Failure
+-----------------
+
+If import fails, the importer will display a list of the connections, along with
+any relevant connection-specific errors, unless a file format error prevents
+parsing the file into a list of connections at all.
+

+Import File Format
+-----------------
+
+Three file types are supported for connection import: CSV, JSON, and YAML.
+The same data may be specified by each file type. This must include the
+connection name and protocol. Optionally, a connection group location, a list
+of users and/or user groups to grant access, connection parameters, or connection
+protocols may also be specified. Any users or user groups that do not exist in
+the current data source will be automatically created. Note that any existing
+connection permissions will not be removed for updated connections, unless
+"Reset permissions" is checked.
+
+This same file format information is available within the webapp, at the
+"View Format Tips" link.
+
+(batch-import-csv-format)=
+### CSV Format
+
+A connection import CSV file has one connection record per row. Each column will
+specify a connection field. At minimum the connection name and protocol must be
+specified.
+
+The CSV header for each row specifies the connection field. The connection group
+ID that the connection should be imported into may be directly specified with
+"parentIdentifier", or the path to the parent group may be specified using "group"
+as shown below. In most cases, there should be no conflict between fields, but if
+needed, an " (attribute)" or " (parameter)" suffix may be added to disambiguate.
+Lists of user or user group identifiers must be semicolon-separated. If present,
+semicolons can be escaped with a backslash, e.g. "first\;last".
+
+```

+```
+
+(batch-import-json-format)=
+### JSON Format
+A connection import JSON file is a list of connection objects. At minimum the connection
+name and protocol must be specified in each connection object.
+
+The connection group ID that the connection should be imported into may be directly
+specified with a "parentIdentifier" field, or the path to the parent group may be
+specified using a "group" field as shown below. An array of user and user group
+identifiers to grant access to may be specified per connection.
+
+```

+
+A connection import YAML file is a list of connection objects with exactly
+the same structure as the JSON format.

+```
