Choose best terms/organization for number of observations
SatNOGS stores the number of observations that have been/will be made by a ground station. What is the best way to represent that in our JSON-LD files?
See this commit for an example of the current handling. Right now it looks like:
observation: {
"id": [URIs],
"numberOf": "total number of observations",
"futureNumber": "number of planned observations"
}
