Below are the core services and interfaces which we think are required.

Services with required supported interfaces:

• ScriptManager service
• XModules
• XBind
• XScriptManager
• ScriptEngine service
• XModules
• XBind
• XScriptEngine 
• ScriptMethod service
• XMethod
  

Set of interfaces:

• XBind
• XMethod
• XModules
• XScriptEngine
• XScriptManager
  

A ScriptManager service manages registered ScriptEngine services. It aggregates the modules and bind functionality of the ScriptEngine services.
A ScriptEngine service represents a script engine for a particular language.
A ScriptMethod service represents a script method for a particular language that may be invoked by StarOffice.

The XBind interface provides methods to bind and unbind a method, which is also associated with a particular context, application or document. A bind will create a ScriptMethod service.

The XMethod interface provides a method to invoke a script method synchronously on a method written in a script language.

The XModules interface provides methods to obtain the set of available libraries, modules and methods or to check that methods exists. Module/Library/Method information may be represented as structs. No hierarchy traversal is required to obtain the information. Hierarchy is implicit in the library/module/method name space. Can be similar in style to the functionality of java.lang.ClassLoader to obtain packages etc.

The XScriptEngine interface provides methods to initiate, query, and monitor a script engine.

The XScriptManager interface provides methods to register/deregister ScriptEngine services.
