[v1.0.0-beta.5] - 2022-01-14

Added

  • Added STAC API - Browseable conformance class
  • Added STAC API - Children conformance class
  • Added description of how to support both search and browse in an API.
  • The paging mechanism via a Link with rel next or prev as defined for Item Search can also be used
    for the STAC API - Features endpoint /collections/{collection_id}/items, as described in OAFeat.
  • The paging mechanism via a Link with rel next or prev as defined for items can also be used
    for the STAC API - Features and STAC API - Collections endpoint /collections.

Changed

  • Limit parameter semantics now match OAFeat. Previously, the behavior was not precisely defined.
  • Filter Extension updates to align with changes to OAFeat CQL2 spec
    • Updated all "CQL" usages to "CQL2"
    • Most conformance class URIs are now prefixed with http://www.opengis.net/spec/cql2/ instead
      of http://www.opengis.net/spec/ogcapi-features-3/
    • Conformance classes http://www.opengis.net/spec/ogcapi-features-3/1.0/conf/basic-cql,
      http://www.opengis.net/spec/ogcapi-features-3/1.0/conf/cql-text, and
      http://www.opengis.net/spec/ogcapi-features-3/1.0/conf/cql-json have had cql replaced
      with cql2 (in addition to the prefix change) to
      become http://www.opengis.net/spec/cql2/1.0/conf/basic-cql2,
      http://www.opengis.net/spec/cql2/1.0/conf/cql2-text, and
      http://www.opengis.net/spec/cql2/1.0/conf/cql2-json
    • Significant changes to CQL2 JSON format, now using op and args structure
    • Spatial operator INTERSECTS is now S_INTERSECTS
    • Temporal operator ANYINTERACTS is now T_INTERSECTS
    • Updated Example 3 (now Example 5) to make it clear that property to property comparisons require the
      Property-Property Comparisons conformance class
    • The CQL2 Case-insensitive Comparison
      (http://www.opengis.net/spec/cql2/1.0/conf/case-insensitive-comparison) conformance class
      that adds UPPER/LOWER terms or function CASEI for case-insensitive comparison has not been added
      to this spec yet, since the definition in CQL2 is in flux.
  • service-desc endpoint may return any service description format, typically a
    machine-consumable one (previous restricted required to be OpenAPI 3.0 JSON)
  • service-doc endpoint may return any service description format, typically a
    human-consumable one (previous restricted required to be HTML)

Deprecated

Removed

Fixed

  • Collection conformance class URI should be https://api.stacspec.org/v1.0.0-beta.XXX/collections instead
    of http://stacspec.org/spec/api/1.0.0-beta.XXX/extensions/collections
  • definition of Item object was missing properties as an attribute
  • Filter Extension - examples of using intervals and timestamps in CQL2 were incorrect and have been fixed
  • Filter Extension - examples are updated so that text and json examples are equivalent
