These are blueprints with no live data - questions are defined but not answered, todos are not checked, test cases are not evaluated. Library components serve as templates that can be reused across multiple projects. - **Project Components**: Live instances in projects (projectId is set). These contain actual project data - questions can be answered, todos can be checked off, test cases can be evaluated, and items can be connected to tasks in the task management system. **What Gets Imported:** When you import a library component, the complete component structure is duplicated into the project, including: - All items (Epics, Work Packages, Todo Lists, Test Suites) with their complete hierarchy and nesting - All questions with their options and configurations (answers are initialized as empty/unanswered) - All todos with their descriptions (completion status is initialized as not done) - All test cases with steps and expected results (evaluations are initialized as not tested) - All conditions with their logic (automatically updated to reference the new item/question/todo/test case IDs in the project) **Automatic Processing:** After import, the system automatically: - Recalculates all conditions to ensure they reference the correct items in the project - Recalculates timeframes based on work packages and their configurations - Adds the imported components to the end of the project component list - Marks the project configuration as changed **Use Case:** This endpoint is perfect for standardizing project setup. Create reusable templates in the library once, then import them into new projects to get a consistent starting structure that can be customized per project.
