Arrow keeps one shared list of contributor disciplines: the kinds of work
people actually do here. The same tags show up in three places:
Bounty board — bounties are tagged with the disciplines they
need, and the board's sections are the categories below.
Contributor map — your profile card
shows up to 3 disciplines that you pick when you register.
Project tooling — matching open work to the people who can do it.
Because everything reads from the same list, the tags always line up. A bounty
tagged Manufacturing: Composites is asking for exactly what a contributor
who registered Composites offered.
Nine categories, each holding a handful of disciplines. The tags describe the
kind of work, not seniority or specific tools. They're broad on purpose, so
they stay useful as projects change.
Engineering
Design & build the aircraft
MechanicalParts, mechanisms, structures — hardware that survives flight
CAD3D modeling, drawings, design for print & machining
ElectricalPCBs, wiring harnesses, power distribution, sensors
AerodynamicsProps, airflow, performance analysis
PowerBatteries, packs, charging, energy storage
PropulsionMotors, ESCs, props — turning stored energy into thrust
CertificationAirworthiness standards, means of compliance, design assurance
Tagging a bounty. The bounty issue form lists
every discipline as a checkbox. Tick the ones a contributor needs to do the
work — most bounties need one to three.
Registering on the map. The /new-contributor Discord command asks for up
to 3 disciplines. Pick the ones you want to be found for, because that's how
other contributors discover you.
Changing the list. The taxonomy is community-approved and versioned, and it
moves slowly on purpose: bounties, profiles, and tooling all reference it.
Additions or renames go through community review, not a quick PR. Think a
discipline is missing? Raise it in the
Arrow Discord.
