Study Notes
Data vs. Metadata
- Data is the raw information itself, like text or images.
- Metadata describes data, providing context. This is like the book's title, author, or publication date.
- Metadata is "data about data."
- Metadata helps organize, understand, manage, and analyze data.
- Data is the actual content, or information.
- Metadata is data about the data, providing context, structure, and additional information.
Real-world Analogy: Books
- Data is the content of a book (words, pictures, information).
- Metadata describes the book (title, author, ISBN, publication date, number of pages).
Technical Example: Digital Images
- Data is the pixels that make up the image.
- Metadata includes the file format (JPEG, PNG), dimensions, resolution, creation date, camera settings, and other details about the image.
Importance of Metadata
- Organizes and locates data by categorizing and indexing.
- Provides data context, meaning, and understanding.
- Aids in managing, preserving, securing, and tracking data.
- Enables data analysis and interpretation.
AI Context
- Source metadata is important.
- Decisions made by the AI, results generated (logical model), and generated documentation (NLG) are crucial metadata components.
- The underlying repository is data-driven.
- Available metadata (in an AI context) includes: source metadata, AI decisions, results (logical model), and generated documentation (NLG).
- Note: In some cases, only metadata, not data, might be available.
