# ocl-examples
A collection of (toy) examples that demonstrate the use of OCL in 
the context of UML as well as SecureUML models. Most of the models 
were developed in the context of the HOL-OCL and SecureUML projects.

## Models
* **[Controller Calendar:](./controller_calendar)** A simple calendar/meeting model using ControllerUML.
* **[Calendar:](./calendar)** A simple calendar/meeting model.
* **[Company:](./company)** A simple company model, inspired by the OCL standard.
* **[Digraph:](./digraph)** A simple tree like (recursive) data structure.
* **[E-Bank:](./ebank)** A simple eBank/Accounting model.
* **[Health System:](./health_system)** A simple health system.
* **[Invoicing Orders:](./invoicing_orders)** A simple invoicing model.
* **[ISP:](./isp)** A simple example of an ISP.
* **[Mini Company:](./mini_company)** A tiny company example modeling a management hierarchy.
* **[Priority Queue:](./priority_queue)** A simple priority queue model.
* **[Red-Black Tree:](./rbt)** A UML/OCL model of red-black trees.
* **[Royals and Loyals:](./royals_and_loyals)** The famous royals-and-loyals example.
* **[Simple:](./simple)** A very simple toy example showing a few OCL syntax variations.
* **[Simple Chair:](./simple_chair)** A simple conference management system.
* **[Simple Filesystem:](./simple_filesystem)** A simple POSIX-like file system model.
* **[Stack:](./stack)** A simple stack.
* **[Vehicles:](./vehicles)** A simple model of vehicles and driver's licenses.
