Notes linking is enabled in 1.6.3 and 1.7. For older releases follow the instructions in HelpOnConfiguration for "url_schemas". Add the word "notes" in lowercase to the schemas.
On the tab: <+>, there is an identifier field
Notes://GunganCen/CA256992000B94BF/BC4B9A3C3F7C5458CA256A6C001A64F1/B0558F2B9DDB41C3CA25741900006827

Change "Notes:", at the beginning of the line to lowercase. MoinMoin will only recognise it as a link if it is lowercase:
