[v1.0.0-beta.1] - 2020-06-02

Removed

  • The API portion of STAC has been split off into a new repository: stac-api-spec and will start being versioned and released separately than the core STAC spec.
  • proj4 string from proj extension
  • Various warnings about how the spec is very early and likely will change.
  • implementations.md (migrated to https://stacspec.org) and how-to-help.md (migrated to https://github.com/stac-utils/stac-ecosystem).
  • commons extension completely removed: Items should contain all properties and not default to a common set at the Collection level
  • ItemCollection removed from stac-spec core repo, will migrate to stac-api-spec as that is the only place it is used.

Added

  • 'alternate' as a listed 'rel' type with recommended 'text/html' to communicate there is an html version.
  • Added a code of conduct based on github's template.

  • Add proj:shape and proj:transform to the projections extension.
  • Collection-level assets extension
  • Instructions on how to run check-markdown locally
  • Timestamps extensions (adds fields published, expires and unpublished)
  • created and updated can be used in the assets to specify the creation / update times of the assets.
  • Tiled Assets extension, for representing data that has been split into tiles

Changed

  • Label extension types were clarified and types in README and JSON schema were brought into alignment
  • Moved item recommendations to best practices, and added a bit more in item spec about 'search'
  • Moved eo:gsd from eo extension to core gsd field in Item common metadata
  • asset extension renamed to item-assets and renamed assets field in Collections to item_assets
  • item-assets extension only requires any two fields to be available, not the two specific fields title and type
  • datetime allows null as value, but requires start_datetime and end_datetime then
  • Extensions sat, scientific and view: At least one field is required to be specified.
  • Single File STAC extension changed to be a complete STAC catalog + GeoJSON FeatureCollection that contains collections and items.
