Consider way_function, the way object passed in has attributes.
Typically, those are OSM tags, but it does not have to be OSM tag.
For example, you can preprocess non-OSM data into PBF to make it look
& feel like OSM in order to let OSRM digest it.
You can assign your nodes and ways with `ref` identifiers of your own
scheme, it does not have to be OSM identifiers.
Moreover, whatever properties are attached to way objects, you can
access them inside lua profiles
local way_i = way:get_value_by_key('this_is_my_custom_way_id)
local way_n = way:get_value_by_key('this_is_my_custom_way_name)
result.name = way_n
result.ref = way_i
result...

result.ref
but the value can be based on a custom scheme, it does not have to be
OSM identifiers.

The last one is a bit out of date w.r.t. Lua fuction names.
