Use cases

In this page you learn what is a use case and find a list of railML® use cases.

While the emphasis of the railML®-wiki lies in documenting single elements in a bottom-up approach, we also try to help users to capture the concepts of railML® via examples and use cases in a top down approach.

What is a use case?

A use case can be defined as a single task, performed by the end user of a system, that has some useful outcome*. It is described as a list of steps (actions or events) to achieve this outcome.

A use case in terms of railML® is an application of data exchange between at least two IT systems in the railway domain, where railML® can be used as a format and language for the data to be exchanged. The aim of the use case description is to formulate requirements on the technical implementation of the data exchange.

What distinguishes a use case from an example is, that examples will typically consist of pieces of railML®-code, whereas use cases will typically be formulated in natural language or Unified Modelling Language (UML). Examples are solutions to use cases.
