Core Responsibilities: Enterprise Knowledge Graph Architecture:

• Design the enterprise knowledge-graph architecture across business, technical, semantic, analytical, and AI-facing domains
• Define the target-state knowledge-graph architecture
• Select the appropriate graph foundation: RDF graph, property graph, or hybrid RDF/property-graph architecture
• Define the canonical entity, relationship, event, attribute, provenance, and metadata model
• Establish graph partitioning, named graph, dataset, tenancy, security, lifecycle, and versioning strategy
• Design graph APIs, query services, semantic services, and downstream integration points
• Define architecture patterns for AI agents, GraphRAG, semantic search, data cataloging, lineage, inference, and analytics

Ontology, Taxonomy, and Semantic Layer Design:

• Own the enterprise semantic model and ensure that business concepts are represented consistently across systems
• Design ontologies using RDF, RDFS, OWL, SKOS, SHACL, and related semantic standards
• Define classes, subclasses, object properties, data properties, constraints, hierarchies, mappings, and equivalence relationships
• Build semantic models that support business definitions, metrics, dimensions, lineage, policy, provenance, and data-governance requirements
• Establish ontology modularization patterns by domain, such as customer, supplier, contract, asset, product, risk, transaction, clinical, regulatory, or research domain
• Define ontology versioning, approval, change-control, release, and rollback procedures
• Translate business terminology into machine-readable semantic models that can be queried and reasoned over
• Build semantic mappings between source systems and the graph layer
