Create alternative title with metadata?

5

I saw in this thread, that the metadata seems to be used somehow, but i dont know how to adapt it to metadata of a custom namespace:

- component: oh-label-item
          config:
            icon: =props.icon
            iconColor: '=items[loop.i.name].state === "ON" || items[loop.i.name].state > 0 ? "green" : "gray"'
            footer: =loop.i.metadata.uiSemantics.config.preposition + loop.i.metadata.uiSemantics.config.location
            title: =loop.i.metadata.uiSemantics.config.equipment
            item: =loop.i.name
