STAC API Enhancements

• MCP API Support

  • Added support for MCP‑based STAC APIs to improve query extensibility and integration.

• STAC Filter Extension (Issue #684)

  • Implemented the STAC Filter Extension, enabling advanced filtering on STAC item properties using standardized filter expressions.

• STAC Query Extension (Issue #691)

  • Added support for the STAC Query Extension, allowing structured queries on item fields such as properties, datetime, and assets.

• View Stac Items Within Collection (Collections Tab) (Issue #677)

  • Enabled viewing of STAC Items directly within a Collection from the Collection tab.

• The collection endpoint returns all collections when no limit parameter is specified.

STAC Item Configuration Improvements

• Simplified STAC Item Configuration

  • Removed the requirement for identical stac-item.json and stac-items.json files.
  • Only stac-items.json is now required for configuration.

• Automatic Property Inclusion

  • All stored STAC Item properties are now automatically included in item responses.
  • No explicit configuration of individual properties is required in stac-items.json.

• Dynamic STAC Extensions Resolution

  • stac_extensions for STAC Items are now dynamically derived based on item properties present at runtime.
  • Eliminates the need for hard‑coding STAC extensions in configuration.

• Collection Default Properties in Item Responses (Issue #680)

  • STAC Items now inherit and include default properties defined at the Collection level when not explicitly set on the Item.

Security

• Geoportal API Token Support
  • Added support for API token‑based authentication for Geoportal APIs, improving security and automation use cases.
