This curriculum spans the technical and organisational challenges of building and maintaining enterprise-scale metadata repositories, comparable in scope to a multi-phase internal capability program for data governance and metadata engineering.

Module 1: Architecting Metadata Repository Infrastructure

Selecting between centralized, federated, and hybrid metadata repository topologies based on organizational data distribution and governance requirements.
Evaluating storage backends (relational, graph, NoSQL) for metadata persistence based on query patterns and lineage traversal performance.
Designing schema evolution strategies to accommodate changing metadata standards without breaking downstream consumers.
Implementing high availability and disaster recovery configurations for metadata services in regulated environments.
Integrating identity providers (LDAP, SAML) for role-based access control at the repository level.
Configuring metadata indexing strategies to balance query responsiveness with ingestion latency.
Establishing capacity planning benchmarks for metadata growth based on source system inventory and refresh frequency.
Deploying metadata services in containerized environments with orchestration (Kubernetes) for scalability.

Module 2: Ingestion Frameworks for Heterogeneous Data Sources

Developing custom connectors for legacy systems lacking native metadata export APIs.
Implementing incremental metadata extraction to minimize load on production databases.
Mapping technical metadata (column names, data types) from diverse RDBMS platforms into a unified model.
Handling authentication and credential management for secure access to cloud data warehouses.
Normalizing metadata from semi-structured sources (JSON, XML) into relational metadata schemas.
Validating completeness and consistency of ingested metadata using checksums and row count reconciliation.
Orchestrating ingestion pipelines with dependency management across interdependent source systems.
Applying data masking rules during ingestion for sensitive metadata elements.

Module 3: Semantic Layer Design and Business Glossary Integration

Aligning business terms in the glossary with technical metadata through explicit term-to-column mappings.
Resolving term ownership conflicts across business units during glossary consolidation.
Implementing versioning for business definitions to support auditability and change tracking.
Enforcing term classification hierarchies (e.g., PII, Financial) with validation rules.
Integrating glossary change workflows with enterprise change management systems.
Linking business metrics definitions to underlying transformation logic in ETL jobs.
Designing search relevance rules to prioritize contextually appropriate terms in user queries.
Automating synonym management and cross-referencing between regional business units.

Module 4: Automated Lineage Extraction and Impact Analysis

Extracting transformation logic from SQL scripts using parser-based tools to build column-level lineage.
Reconciling lineage gaps in compiled or obfuscated ETL workflows (e.g., SSIS, Informatica).
Modeling indirect data flows caused by staging tables or temporary datasets.
Implementing lineage confidence scoring based on source reliability and parsing completeness.
Generating upstream/downstream impact reports for schema deprecation initiatives.
Visualizing lineage graphs with filtering controls to manage complexity in large environments.
