General Connector Properties

Every connector has a name and a "metadata ID." For a source connector, the name is always "Source" and the metadata ID is always zero (0). For a destination connector, the name is configurable and the metadata ID is some value greater than zero. The first destination connector in your channel starts at metadata ID one (1), the next one will be two, and so on. Even if you rename a destination connector, the metadata ID will remain the same.
