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

   Open

   

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
