Are questions asking for data sources or APIs for aviation-related programs on-topic here?
For example, the question Is there an API to retrieve airport departure and arrivals? just came up. There's a bit of discussion there about whether it should be on-topic here or not.
It seems like we've had a few of this type of questions in the past, but I can't remember if there was a consensus regarding them or, if so, what it was. I also didn't find anything about it previously on aviation meta, though I might have missed it.
There is a datasets tag on the site that has some of these questions. The receptions seems to be a be bit mixed, but most of them are low or no votes and quite a large percentage are unanswered.
