v1.0.0

Added

• Extension fields can be used in Item properties, Collections, assets, and item_assets.
• emb:type and emb:dimensions are required wherever the extension is used.

Changed

• Rewrote the JSON schema based on the latest template.
• Embeddings assets are identified by the embeddings role instead of the embeddings asset key.
• Replaced emb:chip_layout with emb:chip_size, emb:stride, and emb:grid_id. emb:grid_id uses Grid Extension designations.
• Replaced emb:quantization with emb:quantization_method and emb:original_data_type.
• Renamed emb:temporal_resolution to emb:temporal_period, using ISO 8601 durations.
• Changed emb:dimensions from an integer to an array of integers (e.g. [768]).
• Updated to the latest stac-extensions/template.
• Moved best practices from requirements.md into the README, removing outdated content.
• Collapsed field tables into a single table.
• Renamed relation types emb:model and emb:decoder to emb:encoder_model and emb:decoder_model. No relation types are required.
• Added emb:grid and emb:quantization relation types, replacing link objects inside the chip layout and quantization objects.

Removed

• data_type and gsd from the fields table; data_type is no longer required.
• sci:publications, processing:datetime, and processing:version from the fields table (see best practices).
• emb:fit_for_use, emb:runtime_parameters, emb:preprocessing, emb:postprocessing, emb:energy, and emb:uncertainty.
• emb:source-data relation type, in favor of derived_from.
