Descriptive: Used for identifying and discovering resources (e.g., title, author, subject, keywords).
Structural: Explains how data components are organized (e.g., how pages are ordered to form a chapter, or how tables relate in a database).
Administrative: Helps manage resources, including technical information (file type, size), creation date, and usage rights/permissions.
Data Architecture: Acts as a blueprint, allowing organizations to map relationships between datasets and improve data pipelines. Examples of Metadata
Digital Photo: Camera type, GPS location, date/time taken, aperture settings.
Document: Author name, creation date, file size, last modified date. Email: Sender, recipient, subject line, time sent. Why Metadata Matters
Searchability: It makes information easy to find (e.g., searching for all photos taken in a specific city).
Organization: It helps categorize and manage large amounts of data, acting as a “digital filing system”.
Context: It provides essential background that gives data meaning, such as knowing when or why a dataset was created.
