Metadata

Introduction

Using metadata, you can provide additional information about an asset type or asset, for example: the contents of a fuel tank, which can differ per type of vehicle.

Adding metadata to an asset type

Click Assets in the navigation menu and open the Types tab.

List of assets including battery pack, generator, and transformer for tracking purposes.

Select the asset type you want to set the metadata for and go to the Metadata tab.
Click the Add Asset Type Metadata button.

Editing asset type with options for settings, visualization, and metadata management.

Enter a name for the metadata, and set its data type and value.

Interface for editing asset type metadata with fields for variable name and value.

Save the changes.

Attention!
Do not copy symbols (such as "," and ".") to the value field. This can cause misinterpretations in the system!

The metadata has now been created.

Override metadata for a specific asset

Click Assets in the navigation menu.

Click on the asset whose metadata you want to override and open the Metadata tab.

Editing asset details including variable name and description in a management interface.

Save the changes. The metadata has now been overwritten for this specific asset.

Using metadata in the portal

Go to the dashboard where you want to show metadata and open the settings of the widget you want to use.
Activate the switch Calculated measurement. This is only possible with following widgets:

Chart
Single Block
Gauge
Heat map
Pie chart
Timeline

Add the metadata in the following format: [#meta:VARIABLE_NAME#]

For example: [#meta:TankContent#]

Now you can perform a calculation using a sensor value.
For example, to display the remaining fuel level as a percentage:

([vehicle_1|fuel_liters] / [#meta:Tank Capacity#]) * 100

Save the changes.
