What are the types of metadata?

Types include technical metadata (schemas, formats, systems), business metadata (definitions, ownership, classification), operational metadata (lineage, quality metrics, usage statistics), and social metadata (ratings, comments, tags). Each type serves different purposes in making data understandable and usable.

Why is metadata important?

Metadata enables data discovery through searchable catalogs, provides context for proper interpretation, supports governance and compliance, documents lineage for impact analysis, facilitates self-service analytics through business definitions, and ensures data quality by communicating reliability and freshness.

What is a data catalog?

A data catalog is a searchable repository of metadata enabling users to discover datasets through search and browse capabilities. It presents technical, business, and operational metadata in user-friendly formats, often with automated collection, collaboration features, and integration with analytical tools.

What is the difference between technical and business metadata?

Technical metadata describes system and structural aspects like data types, schemas, and connections. Business metadata provides business context including definitions, ownership, and usage information. Technical metadata enables system access, while business metadata enables understanding and proper use by business users.

What is data lineage?

Data lineage is metadata tracing data origins, transformations, and consumption points throughout its lifecycle. It enables impact analysis when sources change, troubleshooting when results appear incorrect, and understanding data processing for governance and compliance. Lineage is essential operational metadata.

How do you manage metadata effectively?

Effective management requires automating collection where possible, maintaining business context beyond technical details, keeping metadata current through automated updates, making metadata accessible through appropriate interfaces, encouraging community contribution, and implementing governance processes ensuring quality.

What are metadata management tools?

Tools include enterprise platforms like Alation, Collibra, and Informatica Enterprise Data Catalog, cloud services like Azure Purview and AWS Glue Data Catalog, and open-source solutions like Apache Atlas, Amundsen, and DataHub. These tools automate collection, provide search interfaces, and integrate with analytical ecosystems.

What is the difference between a data catalog and data dictionary?

Data catalogs are searchable repositories with discovery interfaces, automated collection, and collaboration features. Data dictionaries are structured documentation of field-level definitions in standardized formats, often implemented as spreadsheets or documents. Catalogs enable discovery, dictionaries provide detailed reference documentation.

What is the future of metadata?

The future includes AI-generated metadata automating creation and maintenance, active metadata driving operations rather than passive documentation, knowledge graphs organizing semantic relationships, embedded metadata integrated into analytical experiences, and collaborative metadata leveraging community enrichment.
