Introduction
Transformations are applied to datasets to produce new datasets. A transformation includes an application which carries out the processing and a task used to configure the application.

An application provides two entry points: one to build (e.g compile) a task and one to process a dataset. A task is a collection of named text files.

Although it may make sense to use a particular task with more than one application, it is not sensible to arbitrarily combine any task with any application. Thus we introduce the idea of a task interface that specifies which files must or may be present in a task and how these files are to be used. Published tasks are labeled with the interface they provide and published applications with the task interface they expect.

Task interfaces
ADA task interfaces are described on the task interface page.

Applications
Published ADA applications are listed in the application selection catalog.

Tasks
