I have no idea what they mean. Perhaps [MENTION=648695]Calchas[/MENTION] or [MENTION=204888]JAXBA[/MENTION] can explain
As an example, here is the the first of the 499 items:
I also checked the routing rule for the Global Explorer (which IS an MPM-based ticket) and its routing rule is quite simple:
I only know that *O means oneworld airlines. I believe the numbers represent clusters of countries, but I don't know what each number means. GDSs are in the process of making autoprice possible for oneworld RTW tickets. The systems need to be able to validate that the booked itinerary is in accordance with RTW rules, so these are instructions for the pricing system to read. Perhaps xGLOBxx doesn't have everything in the routing written yet. Many other components in the fare rule also dictate what is possible and what not, so routing is just one of them. MPM means max permitted mileage.
