Attribute sets are a collection of linear event layer columns that can be edited as a logic group. The configuration of attribute sets provides flexibility to divide your event editing workflows by responsible party and the way data is collected and referenced.

For example, your pavement type, number of lanes, and median information may be collected from printed engineering drawings and referenced by engineering station measures. In this case, you could configure an attribute set for pavement type, number of lanes, and medians with the default location method as stationing. When you use the Add Linear Event widget to add data from an attribute set, the dialog box is autoconfigured with the designated settings for measures and columns to edit, streamlining your workflow.

In contrast, you may collect functional class, ownership, and speed limit from a Microsoft Excel file provided from a different group, in which the data provided is located by route and mile point measure. You could create another attribute set for functional class, ownership, and speed limit with the default location method as your mile point network.

You may want to have different attribute sets to separate event layers to delegate editing responsibility between users or business units. You can create an attribute set for characteristic data such as access control, terrain type, or grade for that user or the group of users who edit that data. You can create a separate attribute set for event layers that represent pavement characteristics for the user or set of users who edit that data.

Attribute sets are used to create a set or group of event column fields, from one or more event layers, that you can use to add records in the Add Linear Events widget in ArcGIS Event Editor. Each editable field in an event layer is present in the Available Event Layers list, which can be added to a group in the right pane. In addition, some default configurations for the attribute set can be provided, such as the default from measure method, from unit of measure, to measure method, and to units of measure, that drive measure settings in the Add Linear Events widget. Show layer names setting will drive the layer name visibility in the Add Linear Events widget. The administrator can provide preconfigured attribute sets, or you can create your own attribute set using the steps outlined below.

	Expand All	Shows all the attribute fields present within each event layer.
	Collapse All	Hides the attribute fields to show only the event layers.
	Copy Selected Attribute Set	Copies all the attribute fields present in an event from the left panel to the attribute group in the right panel. The copy is made permanent only when you click the Save button.
	New Attribute Set	Creates a new attribute set. The attribute sets created by using this button are saved in the browser. Therefore, these attribute sets are available only to the user's browser.
	Remove Selected Attribute Set	Removes the selected attribute set from the widget. The administrator-configured attribute sets cannot be removed using this button.
	New Group	Creates a new group in the right panel. A group contains event attribute fields. An attribute set is made up of one or more groups. The group is saved permanently by clicking the Save button.
	Remove Selected Group, Layer, or Attribute	Removes a selected group, layer, or attribute from the right panel. The removal is made permanent by clicking the Save button.
	Default Settings	Allows configuration of default settings for attribute sets. These settings include the default network, from method, from measure units, to method, and to measure units for the Add Linear Events widget.
