Background

What is RDF?

RDF is a lightweight RDF ontology ingestion system for DataHub that provides:

• Universal RDF Support: Works with any RDF ontology without custom configuration
• Dynamic Routing: Query-based processing that automatically detects and routes different entity types
• Comprehensive Lineage: Full PROV-O support with field-level lineage tracking
• Enterprise Features: Automatic domain management, structured properties, and governance controls
• Standards Compliance: Native support for SKOS, PROV-O, DCAT, and other semantic web standards

Current State

RDF has been developed as a field solution and is currently being used by enterprise customers for:

• Glossary Management: Importing existing RDF glossaries into DataHub
• Dataset Processing: Converting RDF datasets to DataHub datasets with platform integration
• Lineage Tracking: Comprehensive data lineage processing using PROV-O
• Regulatory Compliance: Meeting BCBS 239 and other regulatory requirements

Technical Architecture

RDF follows a streamlined architecture with a fully modular, pluggable entity system:

┌─────────────────┐    ┌─────────────────┐    ┌─────────────────┐
│   RDF Graph     │───▶│  DataHub AST    │───▶│  DataHub SDK    │
│   (Input)       │    │   (Internal)    │    │   (Output)      │
└─────────────────┘    └─────────────────┘    └─────────────────┘
        │                        │                        │
        │                        │                        │

   Entity Extractors    Entity MCP Builders    DataHub API
   (Modular, Explicit)  (Modular, Explicit)    (Ingestion)

Simplified Flow: Extractors can return DataHub AST directly (no RDF AST layer required). Converters are optional and only needed if an RDF AST intermediate representation is used.

Key Architectural Features:

• Modular Entity System: Each entity type (glossary_term, dataset, lineage, etc.) is self-contained in its own module
• Explicit Registration: Entity types are explicitly registered for clarity and simplicity
• Pluggable Architecture: Follows Open/Closed principle - extend without modifying core code
• Standards-Based: Native support for SKOS, PROV-O, DCAT, and other semantic web standards
• Streamlined Processing: Extractors can return DataHub AST directly, eliminating unnecessary abstraction layers

Motivation

Business Context

Organizations often need to import existing glossaries and ontologies into DataHub. In many cases, those ontologies are managed through RDF. An official RDF ingestion connector would be a valuable tool to integrate with these systems. This would be particularly relevant in sectors that could benefit from DataHub offering pre-existing libraries.

Key Drivers

1. Regulatory Compliance: Organizations need comprehensive data lineage tracking for regulatory requirements (BCBS 239, FFIEC, etc.)
2. Data Governance: Enterprise metadata management requires flexible, standards-based approaches
3. Semantic Interoperability: Cross-system integration demands semantic web standards
4. Operational Efficiency: Current RDF ingestion processes are manual and error-prone
5. Field Solution Demand: Customers require specialized RDF ontology ingestion capabilities

Market Opportunity

• Target Market: Enterprise organizations with complex data governance requirements
• Use Cases: Banking, insurance, healthcare, government, and other regulated industries
• Competitive Advantage: First-mover advantage in comprehensive RDF-to-DataHub integration
• Revenue Potential: Field solution licensing, professional services, and support contracts

Problem Statement

Current Challenges

1. Manual RDF Ingestion: Organizations manually convert RDF ontologies to DataHub entities
2. Limited Standards Support: Existing tools don't support comprehensive RDF standards
3. Complex Lineage Tracking: Regulatory compliance requires detailed data lineage
4. Scalability Issues: Current approaches don't scale to enterprise ontologies
5. Integration Complexity: RDF-to-DataHub mapping requires specialized knowledge

Impact on Organizations

• Time to Value: Weeks to months for RDF ontology ingestion setup
• Resource Requirements: Dedicated technical resources for RDF processing
• Compliance Risk: Manual processes increase regulatory compliance risk
• Operational Overhead: Ongoing maintenance and updates require specialized skills
• Integration Costs: High costs for custom RDF-to-DataHub integration
