# Resource Tagging

Resource tagging enables users to assign tags & custom attributes to the cloud usage and cost data, and allows categorize and analyze costs based on specified attributes such as Cost Center, Department, Owner, Team, and Environment.

#### Creating Resource Tagging Rules

Resource tagging is achieved using [Data Processing Rules](/hybr/features/cloud-cost-management/resource-tagging/data-processing-rules.md), a user-friendly expression based on Cloud Assert's Common Cost Query Language (CCQL)
