Range ought to go between Rate and Minimums (shortened to Mins).
Except for Minimums and Tags, all fields are numbers.
Speed is any number from 3 to 6; one cannot go above or below that.
Accuracy is usually positive (+1, +2, so on), but some rare cases have negative Accuracy. (A weapon with no Accuracy modifier expresses it as +0.) These don't go too high - best I've seen is +6 Accuracy after magical material boni. (No need to worry about those - they're added directly to stats.)
Damage is usually expressed as something like +4B or +3L; there are no cases of a weapon doing negative damage. So that's a plus sign, one or two digits, and a letter specifying Bashing or Lethal damage. (Some weapons don't add to the wielder's Strength, hence the plus sign, and instead deal one big lump of damage - firearms, mostly.) Weapons bearing the Overwhelming tag add a slash and a number after - say, +11L/4.
Defense is the same as Accuracy in terms of expression. There are also weapons that confer negative Accuracy (and by that, I mean kicks).
Rate is a single-digit number from 1 to 5. (Any rate higher than 5 is 5, period.) Some weapons exist with shorter Rates, expressed fractionally - 1/2 means you can only attack with the weapon every other action. However, these are rare, with the context usually being siege equipment.
Minimums is expressed in a stat, usually Attributes but sometimes Abilities, shortened - Str 1, Dex 4, Mrt 4 to provide an example, where 'Mrt' means Martial Arts. This about the max; usually it's one or two stats.
Attune is usually a single-digit number, sometimes two digits.
Tags is expressed in letters or numbers, detailing specific qualities, separated by commas. As an example: 2, O, P, R - Two-Handed, Overwhelming, Piercing, Reach.
It's Mobility Penalty as one field, not two separate ones.
Soak is expressed as, say, +5L/3B - plus sign, number for Lethal damage, slash, number for Bashing damage. (Some players will express Bashing before Lethal, but that's preferences for you.)
Hardness is the same, only without the plus sign.
Mobility Penalty (or just Mobility) is expressed as a negative number in all cases; armor without a mobility penalty expresses it as -0. Largest I've seen is -6, so a single digit ought to do it.
Fatigue is not expressed with a modifier; highest I've seen is 5, so again, a single digit ought to do it.
Attune and Tags are as per weapons, though the only real tag for armor is a marker detailing whether it can be concealed.
