Complete representation of a row from the ‘datasets’ table.

This structure represents a persisted dataset with all database fields, including system-generated identifiers and timestamps. It maps directly to the PostgreSQL schema and is used for reading data from the database.

Fields

• id - Unique identifier (UUID) generated by the database
• original_id - Original identifier from the source portal
• source_portal - Base URL of the originating CKAN portal
• url - Public landing page URL for the dataset
• title - Human-readable dataset title
• description - Optional detailed description
• embedding - Optional vector of floats for semantic search
• metadata - Additional metadata as JSON
• first_seen_at - Timestamp when the dataset was first indexed
• last_updated_at - Timestamp of the most recent update
