Support Maproulette cooperative challenges

[Cj-Malone]

Description

Maproulette cooperative challenges are special challenges that give the user data to work with, eg a new node.

@mvexel will be able to better explain, with JOSM it looks like there is an extra request, eg:

http://127.0.0.1:8111/import?new_layer=false&layer_name=MR%20Task%20215603166%20Changes&layer_locked=false&download_policy=&upload_policy=&url=https://maproulette.org/api/v2/task/215603166/cooperative/change/task_215603166_change.osc

Along with the load and zoom call.

Rapid would have to load that osc file.

A few additional notes

Maybe start with the Tag Fix Challenges (docs), which are a lot easier to prepare and easier to apply. Hey also fit neatly in what was talked about in #585 (comment) with an osm_tags object that might be applied / rejected based on an external source.

However, it might be worth considering if the tag fix challenge data model should be extended first, see maproulette/maproulette3#2299

On the data format of cooperative challenges: If this format where to be used more, I think that would be a good time to also consider making the data format easier to access. The whole osc+base64 (see docs) create quite a big entrance barrier.

Here is a test case for a tag fix challenge https://learn.maproulette.org/en-us/documentation/tag-fix-challenges/

• Rough code to create the geojsonl (with emphasis on the l)
  • The core is the operations section that allows to remove some tagging with one click https://github.com/FixMyBerlin/atlas-app/blob/develop/src/app/api/maproulette/cycleway-shared/route.ts#L112-L125
• MapRoulette https://maproulette.org/challenge/45242/task/227680961
• GeoJSONL https://staging.radverkehrsatlas.de/api/maproulette/cycleway-shared/?ids=62504 for Brandenburg, Germany (can be any osm boundary in Germany with ids being a list of osm id of boundaries (that we processed…))
• Example Location with tag fix on https://rapideditor.org/canary#map=19.00/51.94494/13.88890&background=Brandenburg-DOP20c&datasets=fbRoads,msBuildings&disable_features=boundaries
  • There is the issue of a missing description, which is [MapRoulette Integration] Curly braces in instructions aren't replaced #1419
  • There is also the issue of Validation on task description not helpful when using Mustache Tag Replacement maproulette/maproulette3#2342 which is why I have those dots in the description

If there's a desire to support Tag Fix challenges, maybe that should have it's own ticket. We wouldn't want to confuse closing that issue with full support for Cooperative challenges.
