# Step 1: Understand Metadata

## Overview

Metadata in Sift consists of organization-defined key-value pairs with fixed data types, including string, number, and boolean, that provide a structured way to describe and organize workspace resources beyond their names. Each key is defined once and applied consistently across the workspace, making resources easier to search and filter.

## Where Metadata can be applied

Metadata can be attached to Runs, Assets, Annotations, Rules, Reports, Campaigns, Calculated Channels, and User-Defined Functions, allowing the same organizational structure to be shared across different types of resources.
