Thank you for your answer.
Please go ahead and proceed as planned.
I see no point in arguing about the meritocracy of Strava vs OpenStreetMap. I accept your point of view. I'm sorry for any inconvenience to you and the MTB community. It won't happen again.

Paths follow the highways rules, since they are highways.
In: osm.wiki/Highways
A highway in OpenStreetMap is any road, route, way, or thoroughfare on land which connects one location to another and has been paved or otherwise improved to allow travel by some conveyance, including motorized vehicles, cyclists, pedestrians, horse riders, and others...

1. For a path to appear in OSM someone has to draw it using one of the editors;
2. To have the correct name someone as to go and read the path sign, or just know it.

One must be sure of the official, or locally used path name. Inventing names could be considered vandalism by some mappers.

It seems you are pretending to give the paths some names, not because those names exist in normal real life, but because you just need them to exist for some event, in this case Judging Red Bull Rampage. If that is case it is not in accordance with OSM procedures.

At least make some annotation with all named paths. Use the tag "note". I.e.
note=Temporary name in place for 2018 Judging Red Bull Rampage

Please proceed at your own discretion.

Highway Naming Conventions

OpenStreetMap is a map of the world, created by people like you and free to use under an open license.

OpenStreetMap is a massive database of facts - where the world's roads and paths go, and what they're called. Our challenge is to record those facts, and nothing else.

Lots of different software takes this database and does things with it. The "renderer" that you see on the front page of openstreetmap.org is one (a renderer takes the database and draws a map out of it). There are also "routers", which give driving directions from this database; and many other tools.

The convention in OSM is to use the name that is on the signs on the ground. If you can survey the route or if you can see the signs captured from street cameras with suitable licensing (Mapillary or OpenStreetCam) then you know what to put for the name.

For a street to appear in OSM someone has to draw it using one of the editors (iD, Potlatch2 or JOSM for example) for it to have the correct name someone as to go and read the street sign and having noted it, or maybe you just know it, Then one of the editors are used to add the name.

Dear joelmatos,

Can you please be more specific?

Maybe (?) because of the following at wiki:

"The names should be restricted to the name of the item in question only and should not include additional information not contained in the official name such as categories, types, descriptions, addresses or notes."

In osm.wiki/Names#Name_is_the_name_only

Dear joelmatos,

You are correct. I shouldn't have deleted it. I apologize.

The error on opening_hours was automatically detected by my JOSM and I forgot to correct instead of erasing.

You syntaxe is still wrong. Please have a look at osm.wiki/Key:opening_hours

Caro Josef K,

Lamento o sucedido. Não há nenhuma razão para que o Bairro Padre Cruz não possua a tag landuse=residential e a tag boundary=administrative, tal como diz.

Já procedi à reposição da mesma.

Quando fui analisar a situação nem estava a perceber por que é que, por duas vezes, eu tinha retirado a tag. Finalmente percebi que resultava de um aviso de sobreposição do JOSM quando carregava as minhas edições nesta área. Trata-se de uma área adjacente, também ela landuse=residencial, que numa primeira fase introduzi e a qual, passado algum tempo, alterei as tags. De ambas as vezes devo ter optado por fazer tal porque a área "Bairro Padre Cruz" também é uma boundary, o que me deve ter confundido...

Erro meu. No OSM todos os dias aprendo.

Também redesenhei a outra área para evitar a sobreposição que atrás referi. Penso que agora está tudo correto.

Tenho a perfeita noção de que o OSM é um projeto colaborativo, e uma vez que mapeamos nas mesmas áreas, p.f. contacte quando discordar de algo que eu tenha feito ou alterado.
