Application Layer

The following explains the components of the Application Layer.

Web User Interface

The DSpace Web UI is the largest and most-used component in the application layer.  As of DSpace 7, it has been rebuilt on Angular.io communicating via the REST API to the rest of DSpace.

Web UI Files

The web User Interface code is managed in a separate GitHub Project:

https://github.com/DSpace/dspace-angular/

Quick setup and configuration instructions can be found in the README of that project.

REST API

This component defines the main public API of the Application Layer. See REST API section of the documentation.

DSpace Command Line Launcher

The DSpace Command Launcher brings together the various command and scripts into a standard-practice for running CLI runtime programs. See Command Line Operations

Command Launcher Structure

There are two components to the command launcher: the dspace script and the launcher.xml. The DSpace command calls a java class which in turn refers to launcher.xml that is stored in the [dspace]/config directory

launcher.xml is made of several components:

• <command> begins the stanza for a command
• <name>_name of command_</name> the name of the command that you would use.
• <description>_the description of the command_</description>
• <step> </step> User arguments are parsed and tested.
• <class>_<the java class that is being used to run the CLI program>_</class>

See Command Line Operations for additional details.
