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.<\/p>\n<p>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, \u2026) should be used as the property name in the STAC CQL2 filter.<\/p>\n<p>The complete list of changes to queryables attributes is provided below:<\/p>\n<p>&nbsp;<\/p>\n<ul>\n<li>acquisitionType is renamed as product:acquisition_type<\/li>\n<li>antennaLookDirection is renamed as sar:observation_direction<\/li>\n<li>availabilityTime is renamed as published<\/li>\n<li>cloudCover is renamed as eo:cloud_cover<\/li>\n<li>creationDate is renamed as created<\/li>\n<li>dataTakeID is renamed as eopf:datatake_id<\/li>\n<li>datetime is renamed as datetime<\/li>\n<li>doi is renamed as sci:doi<\/li>\n<li>endDate is renamed as end_datetime<\/li>\n<li>globalCoverageID is renamed as eofeos:global_coverage_id<\/li>\n<li>illuminationAzimuthAngle is renamed as view:sun_azimuth<\/li>\n<li>illuminationElevationAngle is renamed as view:sun_elevation<\/li>\n<li>instrument is renamed as instruments<\/li>\n<li>isCoregistrationPrimary is renamed as eofeos:is_coregistration_primary<\/li>\n<li>majorCycleID is renamed as eofeos:major_cycle_id<\/li>\n<li>missionPhase is renamed as eofeos:mission_phase<\/li>\n<li>modificationDate is renamed as updated<\/li>\n<li>orbitDirection is renamed as sat:orbit_state<\/li>\n<li>orbitDriftFlag is renamed as eofeos:orbit_drift_flag<\/li>\n<li>orbitNumber is renamed as sat:absolute_orbit<\/li>\n<li>organisationName is renamed as providers<\/li>\n<li>parentIdentifier is renamed as collection<\/li>\n<li>platform is renamed as platform<\/li>\n<li>polarisationChannels is renamed as sar:polarizations<\/li>\n<li>processingCenter is renamed as processing:facility<\/li>\n<li>processingDate is renamed as processing:datetime<\/li>\n<li>processingLevel is renamed as processing:level<\/li>\n<li>processorName is renamed as processing:software<\/li>\n<li>productType is renamed as product:type<\/li>\n<li>productVersion is renamed as version<\/li>\n<li>query is renamed as description<\/li>\n<li>repeatCycleID is renamed as eofeos:repeat_cycle_id<\/li>\n<li>sensorMode is renamed as eopf:instrument_mode<\/li>\n<li>snowCover is renamed as eo:snow_cover<\/li>\n<li>stackID is renamed as eofeos:stack_id<\/li>\n<li>startDate is renamed as start_datetime<\/li>\n<li>subject is renamed as keywords<\/li>\n<li>title is renamed as title<\/li>\n<li>uid is renamed as id<\/li>\n<\/ul>\n<p>[\/vc_column_text][\/vc_column][\/vc_row]<\/p>\n<\/div>","protected":false},"excerpt":{"rendered":"<p>[vc_row][vc_column][vc_column_text css=&#8221;&#8221;]A new version of the Catalog will be soon made available in ESA MAAP.
