Introduction 

Domain models 

The extension ships with six domain models that cover the full course catalog domain:

• Course -- The main entity. Holds title, description, content, objectives, target groups, admission requirements, images, and a slug for URL generation.
• Event -- A concrete scheduled instance of a course with start/end dates, duration, price, location reference, booked-up and on-request flags, and an event code.
• SingleEvent -- An individual date entry within a multi-day event, providing fine-grained scheduling (title, start date, end date).
• Type -- Categorises courses (e.g. workshop, seminar, certificate program) with title, description, and slug.
• Location -- Physical venue with name, street, zipcode, and city. Provides a computed full address string.
• ContactPerson -- Contact details (salutation, title, first name, last name, phone, email) linked to courses via MM relation.

Three-level hierarchy 

The data model follows a clear three-level hierarchy:

Course
  |-- Event (IRRE, cascade delete)
  |     |-- SingleEvent (IRRE, cascade delete)
  |
  |-- ContactPerson (MM relation)
  |-- SimilarCourses (MM self-relation)

• Course → Event: One course can have multiple scheduled events (inline relation with cascade delete).
• Event → SingleEvent: Each event can contain multiple single-day entries for multi-day schedules (inline relation with cascade delete).
• Course → ContactPerson: Many-to-many relation allowing shared contact persons across courses.
• Course → SimilarCourses: Self-referencing many-to-many relation for cross-linking related courses.

Frontend plugins 

Four content element plugins are registered:

• CourseList -- Lists courses with text search and type filter. The list action is non-cacheable to support POST-based search.
• CourseDetail -- Displays a single course with all its details, events, contact persons, and similar courses.
• EventList -- Lists upcoming events with filtering. The list action is non-cacheable.
• EventDetail -- Displays a single event with its schedule (single events), location, and pricing.

Search and filter 

The course list plugin provides:

• Text search via a search term input field
• Type filter to narrow results by course type
• Reset button to clear all filters
• Pagination with configurable items per page

Slug management 

Automatic slug generation is provided for the following entities:

• Courses (slug field)
• Events (slug field)
• Types (slug field)

Slugs enable human-readable URLs when used with TYPO3's route enhancer configuration.
