To be fair, derived datasets are probably still in their early stages. But the basic idea would be to apply arbitrary transformations to a dataset after it has been opened (e.g. with `decode_cf=False`) and represent the outcome of this transformation as an entry in the catalog. A suitable transformation function might be something like: ```python def fix_calendar(ds): ds.time.calendar = ""proleptic_gregorian"" return xr.decode_cf(ds) ``` ... but maybe it is still more convenient or useful to handle it in xarray directly (e.g. I don't know if stac has a similar approach).","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,1128759050
