This curriculum spans the technical and operational rigor of a multi-phase infrastructure rollout, covering the design, governance, and resilience engineering required to maintain a production-grade metadata repository across distributed data ecosystems.

Module 1: Architecting Metadata Repository Infrastructure

Select primary storage backend (relational, graph, or document database) based on query patterns and lineage traversal requirements.
Design partitioning strategy for metadata tables to support horizontal scaling across environments (dev, staging, prod).
Implement high-availability configurations using database replication and failover mechanisms for metadata services.
Configure secure cross-account access for metadata repositories in multi-cloud or hybrid deployments.
Integrate metadata storage with identity providers using SAML or OIDC for centralized authentication.
Establish network segmentation and firewall rules to restrict access to metadata APIs and administrative interfaces.
Evaluate and deploy containerized metadata services using Kubernetes with persistent volume claims for stateful workloads.
Define backup frequency and retention policies for metadata snapshots based on compliance and recovery objectives.

Module 2: Metadata Ingestion Pipeline Design

Choose between batch and streaming ingestion based on source system capabilities and freshness SLAs.
Develop schema evolution handling for ingested metadata when source systems undergo structural changes.
Implement idempotent ingestion logic to prevent duplication during retry scenarios in distributed pipelines.
Select serialization format (Avro, JSON, Parquet) for metadata payloads based on size, schema enforcement, and tool compatibility.
Configure dead-letter queues for failed metadata records and define escalation procedures for root cause analysis.
Instrument ingestion pipelines with distributed tracing to diagnose latency and failure points across microservices.
Apply rate limiting and backpressure controls to prevent ingestion overload on metadata repository APIs.
Validate metadata payloads against a canonical schema before persistence to ensure downstream consistency.

Module 3: Metadata Schema Governance

Define canonical metadata models for datasets, pipelines, and business terms using open standards (e.g., Open Metadata).
Establish ownership workflows for metadata entity creation, modification, and deprecation.
Implement version control for metadata schema changes using migration tools like Flyway or Liquibase.
Enforce backward compatibility in schema updates to prevent breaking existing lineage and catalog queries.
Design extensibility mechanisms (custom properties, facets) to support domain-specific metadata without core model changes.
Coordinate schema change approvals across data governance, engineering, and compliance teams via pull request reviews.
Automate schema conformance testing in CI/CD pipelines for metadata service deployments.
Document metadata model decisions in a machine-readable changelog for audit and discovery purposes.

Module 4: Data Lineage and Provenance Tracking

Select lineage granularity (column-level vs. table-level) based on regulatory requirements and performance impact.
Integrate with ETL/ELT tools to extract transformation logic and map it to lineage edges in the repository.
Resolve identity of transient or ephemeral datasets (e.g., Spark shuffle files) to maintain accurate end-to-end lineage.
Implement lineage pruning policies to remove obsolete or stale dependency paths after pipeline decommissioning.
Validate lineage completeness by comparing source-to-target mappings against deployment manifests and DAG definitions.
Cache frequently accessed lineage subgraphs to reduce query latency for large dependency networks.
Support partial lineage reconstruction from logs when native integration with processing engines is unavailable.
Expose lineage data via standardized APIs for integration with data quality and impact analysis tools.

Module 5: Metadata Access Control and Privacy

Implement attribute-based access control (ABAC) to enforce fine-grained visibility into metadata entities.
Mask sensitive metadata fields (e.g., PII column descriptions) based on user roles and data classification tags.
Log all metadata access events for audit purposes, including queries, exports, and permission changes.
Integrate with data classification tools to automatically apply sensitivity labels to metadata entries.
Enforce data residency policies by restricting metadata storage and access to region-specific clusters.
Define metadata declassification procedures for datasets moved from restricted to public domains.
Implement just-in-time access provisioning for privileged metadata operations with time-bound approvals.
Conduct quarterly access reviews to validate active permissions against job responsibilities.

Module 6: Metadata Quality and Validation

Define metadata completeness SLAs (e.g., 95% of tables must have owners and descriptions).
Deploy automated scanners to detect stale metadata, such as datasets without recent access or update activity.
Integrate metadata validation rules into CI/CD pipelines for data model deployments.
Establish reconciliation processes between source system metadata and catalog entries to detect drift.
Measure metadata accuracy by sampling and comparing catalog content against source system introspection.
Set up alerting for anomalies in metadata creation rates (e.g., sudden drop indicating ingestion failure).
Implement automated suggestion engines for missing metadata using ML-based pattern recognition.
Track resolution timelines for metadata quality issues using ticketing system integrations.

Module 7: Disaster Recovery and Metadata Backup

Define RPO and RTO for metadata based on business impact of catalog unavailability.
Implement cross-region replication of metadata storage with conflict resolution strategies.
Test full metadata restore procedures from backups at least quarterly using isolated environments.
Encrypt backup artifacts at rest and manage keys through a centralized key management system.
Validate referential integrity of restored metadata, especially for lineage and ownership relationships.
Document manual recovery steps for scenarios where automated failover is not possible.
Include metadata in broader data platform DR runbooks and coordinate testing with infrastructure teams.
Archive historical metadata snapshots for long-term compliance beyond operational retention periods.

Module 8: Monitoring, Observability, and Alerting

Instrument metadata services with metrics for API latency, error rates, and queue backlogs.
Define thresholds for metadata ingestion pipeline delays and trigger alerts based on business hours.
Correlate metadata service outages with downstream impacts on data discovery and pipeline monitoring tools.
Monitor storage growth trends in metadata tables to anticipate scaling needs and cost implications.
Track user engagement metrics (e.g., search volume, entity views) to identify adoption gaps.
Implement synthetic transactions to verify end-to-end functionality of metadata publishing and querying.
Centralize logs from metadata components into a secure SIEM for threat detection and forensics.

Module 9: Integration with Data Governance and Compliance Frameworks

Map metadata repository entities to regulatory requirements (e.g., GDPR, CCPA, HIPAA) using classification tags.
Automate audit report generation for data access and modification using metadata change logs.
Synchronize metadata ownership with HR systems to reflect organizational changes in real time.
Expose metadata APIs to compliance tools for automated data inventory and risk assessment.
Implement data retention policies in metadata based on the lifecycle of associated datasets.
Enforce metadata documentation requirements as prerequisites for production data pipeline deployment.
Integrate with consent management platforms to reflect user data permissions in metadata attributes.
Support third-party auditor access to metadata with time-limited, read-only credentials and activity logging.
