+The Open edX's `course-discovery` service currently lacks an efficient and flexible way to categorize courses by 
 granular subject areas and verticals. The existing mechanisms (e.g., tags, Primary Subject) are limited, primarily 
 partner-driven, and often misaligned with business-specific needs for taxonomy and categorization.
 Partner-driven use cases are different from business-specific use cases.
 
-For example, if a partner tags a Python course as a programming language course,
-the business wants to tag it as a Data Science tool (to learn and practice Data Science primarily).
+For example, a partner might categorize a Python course under the broad umbrella of programming languages, aligning with general usage.
+However, the business may wish to categorize the same course under Data Science tools,
+highlighting its primary focus on enabling learners to apply Python in Data Science contexts.
