Inizia leggendo il materiale «Points of discussion for axis» e il documento referenziato ProjJson v0-7 per comprendere il primo utilizzo di bearing. Individua le definizioni dello schema e aggiungi l’oggetto bearing proposto, in modo che la sua longitude obbligatoria e le regole di mutua esclusione per id/ids corrispondano all’issue; il lavoro è completato quando la definizione mancante è presente e coerente con la definizione di meridian.
