How to add or remove metadata properties for tag objects

1. In the explorer, right click on “Edge ACM”, go to “Edit Metadata” and select “Tag”
   

   

2. A new tab will open that looks like this. You can click on the + in “Properties” to add new metadata properties.
   

   

3. Each property has a name, type, and default value. You can click on the trash can icon on the right of a property to delete it. Default values will only be applied to newly created tags.
   

   

4. Once you’re done, click the save icon in the top left
   

   

5. If tags have metadata, then you will see a “Metadata” tab when editing a tag that contains the added properties.
   

   

6. The metadata properties will also appear when doing multi-item editing.
   

   

7. Restart “Edge ACM” to have the metadata properties take effect.
