• Institutional Knowledge Links - Links unstructured conversations and decisions directly to structured data assets to preserve institutional knowledge.
• Incident and Thread Context - Preserves context from AI threads and incidents to maintain a historical record of institutional knowledge.
• Knowledge Management - Captures and preserves domain knowledge by linking descriptive notes to specific assets and workflows.
• Freshness Monitoring - Monitors freshness signals and metadata to prevent the use of decayed or unreliable data.
• Data Trust Monitors - Aggregates freshness metrics and certifications to determine if a data asset is trusted for use.
• Automated Stewardship Workflows - Integrates AI agents to automate metadata governance through description suggestions and sensitive data identification.
• Governed Agent Memory - Stores conversation logs and AI agent learnings as governed memory for reuse by humans and AI.
• Decision History Tracking - Preserves historical context by storing remediation notes and decisions associated with data assets.
• Database Metadata Discovery - Automatically maps and navigates technical asset structures via system catalogs and metadata collection.
