Sorry I was not on line when this was being discussed - but Peter gave me the lead to contribute.
"Indicator" is supposed to be a short qualifier of the commonname that creates a uniqueness to the stop point name. There is a list of approved abbreviations (maybe incomplete from what Peter has said) - but from experience there is also a provisional list of "preferred indicators" that are about to be promoted nationwide (this is expected to be extended in the light of experience). I attach that list for information ... they are reasonably well adhered to already in the SE, EM and EA regions - but not necessarily so well used elsewhere at present (some regions are much better than others - it rather depends how much legacy data was permitted to get into NaPTAN when it was first created). I am under no illusions about the fact that indicators are not good at many stops now - and it will take years before adherence to the principle of them being a short qualifier of the common name is fully adhered to. As for before and beyond, they are not words that currently appear in the list at present - but I can see that they might be useful additions --- but NOT bey and bef which are not abbreviations which are in common usage anywhere!

For example 'adj' is missing from the list which is frequently used for 'adjacent'. Do be aware that the use of the indicator field is still being refined and not everything that is in the current database is good practice. Possibly Roger (Slevin) or Peter (Stoner) will be able to give us some more detail on this.

NaPTAN preferred indicators "stop" "stance" "stand" "bay" "opposite" "opp" "outside" "o/s" "adjacent" "adj" "near" "nr" "behind" "inside" "drt" "entrance" "main entrance" "side entrance" "front entrance" "back entrance" "north entrance" "east entrance" "south entrance" "west entrance" "arrivals" "depatures" "in" "N-bound" "Northbound" "S-bound" "Southbound" "E-bound" "Eastbound" "W-bound" "Westbound" "NE-bound" "NW-bound" "SW-bound" "SE-bound" The words stop, stand, stance, bay can be followed by an alphameric string to allow for stop codes A, 1, A1, 1A, 23, FG etc ... we limit the numeric part to 99 and the alpha to two characters either before or after the numeric. Words which indicate a relationship (nr, opp, o/s, adj, etc) can be followed by an alphameric string to allow for house numbers 3, 27A etc. In this case the numeric component has to allow for values to 9999, with or without a single following alpha character.
