This curriculum spans the design and operationalisation of metadata ingestion systems with the breadth and technical specificity of a multi-phase data governance rollout, covering architecture decisions, pipeline engineering, and stewardship workflows typical of large-scale catalog implementations.

Module 1: Defining Metadata Scope and Classification Frameworks

  • Select metadata domains (technical, operational, business, social) based on stakeholder query patterns and lineage requirements.
  • Establish metadata classification taxonomies aligned with existing data governance policies and enterprise data models.
  • Decide whether to adopt open standards (e.g., DCAT, Dublin Core) or proprietary classification schemas based on interoperability needs.
  • Implement metadata tagging conventions for data sources, including versioning, ownership, and sensitivity labels.
  • Balance granularity of metadata capture against storage and processing overhead in high-volume environments.
  • Define metadata ownership roles per domain and integrate with IAM policies for attribute-level access control.
  • Design backward-compatible classification updates to prevent pipeline breakage during schema evolution.
  • Map metadata attributes to regulatory requirements (e.g., GDPR, CCPA) for automated compliance reporting.

Module 2: Evaluating and Selecting Metadata Repository Platforms

  • Compare graph-based (e.g., Neo4j) vs. document-based (e.g., MongoDB) vs. relational storage for metadata relationship density.
  • Assess native support for metadata standards (e.g., Apache Atlas, OpenMetadata, Alation) versus custom-built solutions.
  • Validate platform scalability under concurrent ingestion from 50+ source systems with metadata bursts.
  • Test API rate limits and authentication mechanisms for third-party tool integrations (e.g., ETL, BI, MDM).
  • Evaluate vendor lock-in risks when using cloud-managed metadata services with proprietary APIs.
  • Measure time-to-query performance for lineage traversal across 10+ hop dependencies.
  • Determine support for temporal metadata (schema and value changes over time) in candidate platforms.
  • Verify audit logging capabilities for metadata modification events at field level.

Module 3: Designing Metadata Ingestion Pipelines

  • Choose between batch ingestion (scheduled) and event-driven (Kafka-based) models based on freshness SLAs.
  • Implement idempotent ingestion logic to handle duplicate metadata payloads from source retries.
  • Develop transformation rules to normalize inconsistent naming conventions from heterogeneous sources.
  • Integrate retry and dead-letter queue mechanisms for failed metadata records during transmission.
  • Optimize payload size by compressing large metadata blobs (e.g., query plans, JSON schemas).
  • Orchestrate ingestion workflows using Airflow or Prefect with dependency-aware scheduling.
  • Embed lineage context (source system, extractor version, timestamp) into every metadata record.
  • Apply schema validation against a central metadata contract before ingestion.

Module 4: Extracting Metadata from Heterogeneous Sources

  • Configure JDBC drivers to extract table DDL, constraints, and index metadata from legacy RDBMS.
  • Parse DDL scripts from version-controlled repositories when direct database access is restricted.
  • Use native APIs (e.g., Snowflake Information Schema, BigQuery REST) to pull cloud data warehouse metadata.
  • Intercept ETL job configurations (e.g., Informatica, Talend) to extract transformation logic and dependencies.
  • Scrape BI tool metadata (e.g., Tableau workbooks, Power BI models) for semantic layer definitions.
  • Instrument Spark applications to emit runtime metadata (schema inference, partitioning, skew).
  • Extract API specifications (OpenAPI) to register data contracts and endpoint-level metadata.
  • Handle authentication and credential rotation for source systems with short-lived tokens.

Module 5: Implementing Metadata Quality Controls

  • Define completeness thresholds (e.g., 95% column description coverage) for critical datasets.
  • Deploy automated checks for stale metadata (e.g., unrefreshed in >30 days) with alerting.
  • Validate referential integrity between metadata entities (e.g., foreign key to column mapping).
  • Measure accuracy of inferred lineage by comparing against manually documented workflows.
  • Implement anomaly detection on metadata change rates to flag potential configuration drift.
  • Enforce data type consistency across source, staging, and target representations.
  • Track metadata defect resolution SLAs across stewardship teams using ticketing integrations.
  • Run reconciliation jobs between catalog metadata and source system system tables.

Module 6: Managing Metadata Lineage and Dependency Graphs

  • Choose between coarse-grained (table-level) and fine-grained (column-level) lineage based on impact analysis needs.
  • Model indirect dependencies (e.g., shared dimensions, lookup tables) in lineage graphs.
  • Implement incremental lineage updates to avoid full reprocessing on minor changes.
  • Support forward and backward traversal for impact and root cause analysis workflows.
  • Handle schema evolution in lineage by versioning transformation rules and mapping sets.
  • Integrate with data observability tools to annotate lineage with freshness and quality signals.
  • Optimize graph storage for sub-second query response on multi-hop traversals.
  • Mask sensitive nodes in lineage for non-privileged users without breaking path integrity.

Module 7: Securing and Governing Metadata Access

  • Implement attribute-based access control (ABAC) for metadata fields containing PII or business logic.
  • Enforce row-level filtering in metadata queries based on user role and data domain membership.
  • Encrypt metadata at rest and in transit, especially for cloud-hosted repositories.
  • Integrate metadata access logs with SIEM systems for compliance auditing.
  • Define data classification propagation rules from source to derived datasets in the catalog.
  • Apply retention policies to metadata records based on source data lifecycle.
  • Restrict write access to metadata attributes to approved stewardship roles and automated pipelines.
  • Validate metadata changes against governance policies using pre-commit hooks in CI/CD.

Module 8: Monitoring, Alerting, and Operational Maintenance

  • Instrument ingestion pipelines with metrics for latency, throughput, and error rates.
  • Set up alerts for metadata staleness exceeding defined freshness SLAs.
  • Monitor repository storage growth and plan capacity based on ingestion trends.
  • Automate schema migration scripts for metadata model version upgrades.
  • Conduct regular consistency checks between metadata and source system states.
  • Rotate API keys and service accounts used by ingestion connectors on a quarterly basis.
  • Perform failover testing for high-availability metadata repository clusters.
  • Document runbooks for common failure scenarios (e.g., backpressure, schema drift).

Module 9: Enabling Discovery and Consumption Workflows

  • Implement full-text and faceted search with relevance ranking tuned to enterprise terminology.
  • Expose metadata via REST and GraphQL APIs for integration with custom applications.
  • Generate data profile summaries (sample values, distributions) for new datasets.
  • Integrate with IDEs and notebooks to provide inline metadata tooltips during development.
  • Support bookmarking and annotation features for collaborative data exploration.
  • Embed metadata links in operational dashboards for contextual data understanding.
  • Provide export functionality for metadata subsets in standard formats (JSON, CSV, RDF).
  • Track metadata usage patterns to prioritize curation efforts on high-traffic assets.
