properties arguments in Load_Collection?

[vincentsarago]

the properties is defined as a process https://github.com/Open-EO/openeo-processes/blob/master/load_collection.json#L181-L219

I think we shouldn't support this but replace it with more advances STAC API queries

Replacing it on the user facing side (i.e. in the client) would make the process graph not portable to the other openEO back-ends. The replacement should be done after that the process graph is being defined, on the back-end side the properties can be translated to a "normal" STAC API query.

Some useful resources:

An example about the /queryables endpoint: https://github.com/Open-EO/openeo-api/blob/c5a45b4647b06e313a4f099e9119bfa3cca5c6a3/extensions/commercial-data/README.md?plain=1#L85
