Procedure
1 Set Up the Global Plug-In Information on page 195
To create a plug-in, you must point Orchestrator to the relevant XML schema definition and the source
files for the application and plug-in. You must also define the behavior of the plug-in when Orchestrator
starts and provide a root object for the hierarchy of objects that the plug-in exposes.
2 Map Objects in the Plugged-In Technology to Scripting Types and Inventory Objects on page 196
To allow Orchestrator to access objects in a plugged-in application, you must define how and where the
plug-in finds those objects.
3 Define Enumerations on page 199
You can define enumerations in the vso.xml file to set global values that apply to all objects of a certain
category.
4 Map Classes and Methods to Classes and Methods in the JavaScript API on page 199
Orchestrator monitors objects in the plugged-in application and performs operations on them by running
workflows, policies, and actions. You map in the vso.xml file the classes and methods from the plugged-
in technology and from the plug-in implementation to JavaScript classes and methods in the Orchestrator
JavaScript API.

for the application and plug-in. You must also define the behavior of the plug-in when Orchestrator starts and
provide a root object for the hierarchy of objects that the plug-in exposes.
Procedure
1 Create a file named vso.xml.
2 Set up the <module> element to provide basic information about the plug-in, including a pointer to the
Orchestrator plug-in XML schema definition.
The <module> element in the vso.xml file for the solar system example sets the plug-in name to
SolarSystem, sets the version number, and provides the path in the DAR archive to the icon that represents
this plug-in in the Orchestrator Inventory view and selection dialog boxes.
<?xml version="1.0" encoding="UTF-8"?>
<module xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

name="SolarSystem" version="1.0.0" build-number="4" image="images/solarSystem-16x16.png">
3 Provide a description of the plug-in in the <description> element.
The following example shows a <description> element for the solar system.
