Design and maintain schemas and semantic data models for entities, relationships, and capabilities
Build and maintain knowledge graphs across heterogeneous product data
Create and maintain source and metadata parsers, including source-code/AST parsing for automated structure extraction
Implement typed programmatic interfaces and data-access layers on top of the knowledge layer
