Changes to the queryable names into a near-future version of the ESA MAAP Catalog
A new version of the Catalog will be soon made available in ESA MAAP. The new release introduces updates to the handling of queryables attributes, ensuring alignment with the STAC API specification and improving consistency across services. According to the STAC API specification, queryables must not be used as HTTP query parameters, they are intended exclusively for use within filter expressions defined in CQL2. The new names will be listed in the /queryables response.
It is important to note that the new Catalog has only renamed queryables to align them with the STAC standard. All standard STAC HTTP parameters continue to function as before. When constructing queries, the queryable name (e.g. processing:level, sci:doi, …) should be used as the property name in the STAC CQL2 filter.
