SECTION 15D — CATEGORY EXTRACTION WORKFLOW

​
15D.1 What a Category Extraction Is

A Category Extraction is a standalone document that isolates a specific cherry-picked set of news categories from individual newsletters over any aggregation range (Week, Month, Quarter, Bi-Annual, Annual). It produces a focused, category-specific output from the larger aggregated data.

​
15D.2 Creation Flow (Editor-Only)

  1. Select Aggregation Type: Editor selects the source aggregation type (Weekly Compilation, Monthly Magazine, Quarterly Collection, Bi-Annual Compendium, or Annual Yearbook) and the specific period.
  2. Category Selection UI: A checkbox-based interface displays all news categories that exist across the newsletters in the selected aggregation range.
  3. Cherry-Pick Categories: Editor selects one or more categories. All news items falling under the selected categories across the aggregation range are included.
  4. Document Generation: Backend assembles the extraction document containing only the selected categories.
  5. Billing Flag: Editor sets the count_in_billing flag (default: false). When false, this document is not counted towards the Teacher’s billable page count.
  6. Editor Review & PDF Generation: Standard pipeline — Editor reviews, approves, WeasyPrint generates PDF.
  7. Storage: The extraction document is saved as its own entity in the same folder structure used by the source aggregation type.
