Most operations that you perform with Progress Developer Studio for OpenEdge take place within the context of a project. You can create multiple REST projects and maintain them concurrently in your workspace. By default, the REST project opens in OpenEdge Server perspective.
Note: To deploy REST Services to a PAS for OpenEdge server, you must use an ABL WebApp project with a REST service type.

You can create a REST project and a REST module. For details, see Create a REST project.
