if this is the proper term used for pipelines, then this would be the right one, Otherwise, =multi (like sports) would be the best. but you would not need such a tag, since it would be substance=gas substance:detailed=multiphase_gas if you keep it at two levels of detail (water, gas, oil, fuel, sewage, heat, coolant, etc), include a catch-all like “other”, so if someone has a maple syrup pipeline (for instance - one can only dream) it can get thrown into other. There might also need to be an “industrial” one, in case someone is moving some industrial chemical that wouldn’t fit into the scheme either, though I’m not sure how exactly that would be worded. micro-mapping certain industrial facilities would require something like this. > > substance=fuel > substance:detailed=drinking_water isn't it just as error prone as substance=fuel fuel=drinking_water ? using the colon separator would keep from making additional tags (everything would be kept in the substance tagspace) - especially generic tags like fuel= water= gas= which might have uses elsewhere (like the water_tap discussion here earlier) or be confused for other uses (like not a subkey, but a straight key by itself), someone could stick fuel=unleaded_87 onto a gas station. Or does that already exist? Javbw
