Exchange Schema Aviation specification sold

I have not written this one up yet, and I would rather leave it blank than put words in the steward's mouth. The entry is verified and the facts in the sidebar are confirmed — the reading is still to come.

Not enough of this standard was readable to place it in a band. That is a limit of what I could see, not a finding against the standard.

A separate measure from the Kin Score, which rates API providers. This rates how current a standard is in how it is expressed, published and paid for — not how good it is. EDIFACT and X12 score low here and move an enormous share of world trade.
Licence evidence: sold found on the standard's page.
