We provide battle-tested patterns, reusable code, and user-friendly tools that work across any platform—from genome research to media assets to financial lineage requirements.

Key Innovation: Building blocks over buzzwords—Integration → Storage → Democratization → Use patterns that transcend individual vendor choices.

Project Status: Incubation phase with active development of technical assets, community standards, and implementation guidance.

Graph-First Approach: Native property graph databases replace relational complexity with intuitive relationship modeling, enabling metadata management patterns that scale from departmental repositories to enterprise knowledge graphs.

What We’re NOT


The Market Reality

The Data Catalog Proliferation Problem

Too many data catalog vendors crowd the market today, each claiming unique advantages while delivering similar discovery interfaces. How can enterprises choose? The answer isn’t picking winners and losers—it’s focusing on fundamental patterns that work regardless of vendor selection.

The User Experience Gap

Reality check: Enterprise knowledge workers are not full-stack AWS cloud developers. Cloud data catalogs, while promising, remain immature compared to pre-cloud enterprise tools like InfoLibrarian Studio, ERwin, and others that provided intuitive visual interfaces.

The Metadata Diversity Challenge

Metadata management extends far beyond data warehouses and MDM:

EMM 2.0 Framework

Core Principles

  1. Metadata Over Meetings

    • Machine-readable lineage and schemas via modern API standards.
    • Power pipelines with automated metadata repositories, not manual curation.
    • Executable metadata that certifies lineage integrity in real time.
  2. Execution Beats Excuses

    • Real-time metadata validation in ETL/Kafka streams.
    • Certifies lineage integrity at commit, not in manual reviews.
    • Focus on operational metadata over catalog maintenance.
  3. Federated, Not Foreign - Flexible Architecture

    • Support for both federated networks AND standalone isolated repositories.
    • Compatible with any graph database (Neo4j, Amazon Neptune, Azure Cosmos DB).
    • Self-hosted and cloud deployment options for cost and sovereignty control.
    • Works with existing catalogs as federation endpoints, not replacements.
  4. AI as Muscle, Not Marketing

    • AI predicts risks, auto-tags lineage, and builds semantic knowledge graphs via GraphRAG.
    • Enables cross-border lineage certification through property graph models.
    • Harvests metadata relationships for dataset scoring, bias detection, and lineage verification.
    • Leverages modern graph databases to power relationship-centric metadata repositories.
  5. Standards, Not Sellouts - NO VENDOR LOCK-IN

    • MIT-licensed, vendor-neutral flows based on open universal metamodel foundations.
    • Metadata moves freely through property graph architectures, never trapped.
    • Zero vendor lock-in: Your metadata, your infrastructure, your control—always.
    • Open standards evolution (OpenLineage + Neo4j + GraphRAG) over proprietary platforms.

The Building Blocks Approach

EMM 2.0 focuses on four fundamental patterns:

Integration → Storage → Democratization → Use

These building blocks remain constant whether you’re managing:

Metadata Repository Patterns

EMM 2.0 defines four fundamental repository architectures:

Federated Metadata Networks

Standalone Metadata Vaults

Hybrid Metadata Architectures

Knowledge Graph Metadata

Metadata Repository Architectures: The Heart of EMM 2.0

EMM 2.0’s strength lies in its flexible, vendor neutral open graph metamodel repository architectures, designed for real-world metadata challenges:

These architectures leverage the InfoLibrarian-inspired universal metamodel, ensuring metadata flows freely across platforms without vendor lock-in. Example: A Neo4j-based repo with MATCH (asset)-[:LINEAGE*]->(report) queries certifies BCBS 239 lineage in real time. GraphRAG enhances discovery with semantic queries like MATCH (concept)-[:RELATED_TO*2..4]-(insight) RETURN insight, powering AI-driven metadata insights.

Technical Architecture

The Modern Stack

EMM 2.0 = Native Graph Databases (Neo4j/Neptune) + GraphRAG Intelligence + Federated Property Models + Sovereignty APIs + Real-Time Certification + Open Standards Integration

Modern Capabilities That Fulfill Early EMM Vision

The InfoLibrarian Heritage Advantage

The InfoLibrarian legacy of open universal metamodel and property graph architectures (pioneered before Neo4j existed) aligns perfectly with modern GraphRAG and knowledge graph requirements. The goal isn’t to replace graph-based catalogs, but to ensure enterprises can implement metadata management with complete vendor neutrality.


The Evolution of Enterprise Metadata Management

From Execution Engines to Discovery Platforms

The early era of Enterprise Metadata Management (2000-2015) produced powerful execution-focused tools that understood metadata as fundamentally relational networks, not tabular catalogs. InfoLibrarian’s open universal metamodel and property graph architecture, with 300+ adapters, enabled complex legacy-to-cloud transformations decades before modern graph databases matured. ER/Studio provided visual lineage crucial for SOX, Basel II, and AML metadata requirements. Rochade powered semantic layers that enabled Business Objects to pioneer semantic data platforms. These solutions were production systems that certified lineage for trillion-dollar financial institutions navigating Sarbanes-Oxley, Basel frameworks, and anti-money laundering requirements.

The Current Challenge

The industry correctly identified metadata as networks of relationships requiring flexible, graph-oriented models. However, implementing these concepts using relational databases created universal technical debt—complex schemas, expensive JOIN operations for multi-hop queries, and sophisticated ORM layers to simulate graph capabilities.

The maturation of native graph databases (Neo4j since 2007, enterprise-ready by 2015) and recent GraphRAG advances now enable the relationship-centric metadata management that early EMM pioneers envisioned. Many modern data catalog vendors have adopted graph technologies—which validates the original vision. However, the challenge isn’t technology choice, but vendor neutrality: ensuring enterprises retain control and flexibility regardless of which graph database, cloud provider, or catalog platform they choose.

The Strategic Positioning Opportunity

Data sovereignty regulations—including CCPA, India’s DPDP Act, and EU’s DORA operational resilience requirements—create strategic advantages for federated metadata approaches. The InfoLibrarian heritage of relationship-centric metadata modeling (property models before property graphs were mainstream) aligns perfectly with these requirements.

Professional Path Forward

The opportunity: Organizations implementing EMM 2.0 patterns position themselves as thought leaders in the next generation of enterprise metadata management, while maintaining complete control over their metadata destiny—no vendor lock-in, ever.

Building Blocks Over Buzzwords: Rather than promoting specific vendors or criticizing others, EMM 2.0 focuses on fundamental patterns that transcend individual platform choices. Integration, storage, democratization, and use—these building blocks remain constant across all metadata management scenarios.

Our Approach: Engineering-first, community-driven development of practical metadata management patterns that enterprises can implement regardless of their technology choices. EMM 2.0 builds on decades of enterprise metadata experience, including proven InfoLibrarian universal metamodel approaches and hard-earned trade secrets from the implementation trenches, to deliver executable solutions for the many diverse use cases that metadata management serves.

Reality Check: Enterprise knowledge workers are not full-stack AWS cloud developers. Cloud data catalogs, while promising, remain immature compared to pre-cloud enterprise tools like InfoLibrarian Studio, ERwin, and others that provided intuitive visual interfaces. EMM 2.0 bridges this gap with user-friendly, no-code approaches that work for both technical implementers and business users.

Success Metrics: Success metrics include metadata repositories that enable operational lineage certification without vendor dependencies, cross-jurisdictional data traceability without centralized architectural lock-in, and improved project success rates through execution-focused metadata that organizations own and control.
