usage and maturity about datacube HOT 2 OPEN

Hi @betolink, I saw this question of yours and wondered whether you ever received a reply or figured out a solution yourself. I'm quite interested in semantics issues around EO and geospatial data and find your question very relevant. The concept of 'data cubes', 'collections', and alike are, if at all, not consistently defined across major actors in the field. Without proper semantics we will however struggle to achieve the interoperability which is at the core of STAC and ARD.

Hi Peter, we are still trying to figure out the semantics. I guess it could be both ways, if the "assets" in a cube align into a common grid and time dimension, then the cube could be represented at the collection level, in our case the data is sparse and do not necessarily align into a coherent grid and time dimension. Because of this I think we are going to go with a "collection of cubes" approach.
