User blog:BigSleep/Alternate Reality Versions vs Others vs Related

I'm sure there is an answer to this, but after searching the Help, I couldn't find it. What's the difference between Alternate Reality Versions, Others, and Related? I couldn't find definitions for them, though maybe I just wasn't looking in the right place.

While editing the Punisher page, I didn't understand why the Punisher 2099 (Jake Gallows) was in Others, but not Alternate Reality Version. Jake Gallows would have been the mainstream Punisher in that Alternate Reality. Gold Heart and Vendetta seem to be Other 2099 versions of that mainstream Alternate Reality Punisher, just as the Other versions of the Punisher in the 616 Universe (Rachel Cole Alves, Carlos Cruz, Lynn Michaels, etc.). But if I moved Jake Gallows to Alternate Reality Version, because he's the mainstream version of that Alternate Reality, then wouldn't that same reasoning apply to the Noir Punisher, the Marvel Knights 2099 Punisher, the Old Man Logan Punisher etc. who are also under Others, but are the mainstream Punishers in those Alternate Realities? And then wouldn't that same reasoning apply to the Amalgam Punisher in Related? The three other "Punishers" in Related all seem to be obvious homages or parodies with similar, but not identical names (Punisaur, Adjudicator, and Pulverizer), except for the Amalgam Punisher.

So, I chose nothing, not wanting to run amuck on a wrong idea only to have it undone without explanation. Are my instincts correct?
 * Are Alternate Reality Versions the mainstream versions in an Alternate Reality?
 * Are Others lesser, unofficial versions in any particular reality?
 * Are Related obvious homages/parodies with similar, but not identical names?
