Import / Update From JSON dialog

This dialog allows you to import or update the network from a JSON file.

To display this dialog:

• Right-click a checked out network/control data set in either the Explorer window or Model Group window, then select Update From JSON.
• Click the Update network/control from JSON button in the Task Sequence editor.

Item	Description
JSON File	Clicking the ellipsis button displays a standard File Open dialog, which allows you to select a JSON file that you want to update from. Note: This option is only available when the Import / Update From JSON Data dialog is accessed from the Task Sequence editor.
Type of update	Update and Add Updates network objects that already exist in the network and adds objects that do not exist Delete Uses the primary key fields in the JSON data to identify network objects for deletion. Other fields are ignored Mixed (based on data field) Allows you to carry out deletion, additions and updates using the same JSON file. Mixed mode uses an additional field (Action) in the JSON data. If this field contains the character - (minus), the network object will be deleted in the same way as in the Delete option. If the field is blank, the network object is added or updated as in the Update and Add option
Unspecified units are:	User units Fields that have no units information will be imported using the current user units. If the data was originally exported from InfoWorks WS Pro, any user units are stored for a specific user on a specific machine. If you are a different user on a different machine, it is up to you to ensure that units agree. Native units Fields that have no units information will be imported using native units. (When exporting data for subsequent import or update we recommend the use of InfoWorks WS Pro native units for portability.)
Flag to use for new / updated data:	This flag should be used for new or updated data added to the network from the JSON file. You can either use the default #V flag, or a flag you have created in advance using the User Defined Flags dialog. The chosen flag is used if the JSON field does not have a corresponding flag field. If the JSON data contains a flag field, the flag from the JSON is used, even if the flag is unset.
Only update existing data that has flag:	You can choose to update only the data in your network that has the flag specified here.
Only flag genuine changes to data values	Does not set the flag if the updated parameter has not changed.
Allow blank fields in JSON to overwrite existing data	Do not check this box if your JSON data includes only data that has changed and you want other fields left as they are. Fields that are not listed in the JSON file are ignored completely. Only fields that are listed in the JSON are affected.
Renaming of node forces renaming of connected links	Check the box if your node names have changed and you want to maintain connectivity information. If you do not choose this option you will lose the following connections for nodes whose names have changed: network connectivity information for links connected to the nodes link to any control data associated with this node
Update uses Asset ID field to identify data items	If checked, the Asset ID field of the object in the database is used instead of the object's InfoWorks WS Pro ID (NodeID or USNode.DSNode.Suffix for example) when applying changes to existing records and identifying duplicate records.
Use Digitization Defaults	If checked, digitisation default values are used for fields of added network objects that do not already have a value in the JSON file.
Save	Saves all the selected options in the dialog, and adds them in the task sequence. Note: This option is only available when the Import / Update From JSON Data dialog is accessed from the Task Sequence editor.
