eo:bandsdefinitions still allowed in Item Properties? The schema still allows them there, but it no longer allows them to be referenced by array index from the Asset. The spec text is "eo:bands: In previous versions eo:bands was allowed to be used on the asset-level referencing via array indices to the actual bands in Item properties. Starting with STAC 1.0.0-beta.1 you are now allowed to place the full eo:bands array with all Band Object information in Item assets as described in general in the STAC Item."
A summary for a field can be specified in two ways:
- A set of all distinct values in an array: The set of values must contain at least one element and it is strongly recommended to list all values. If the field summarizes an array (e.g. instruments), the field's array elements of each Item must be merged to a single array with unique elements.
