A documentation abstraction layer facilitates the abstraction of help calls. When help is instigated in a client program, the client program may send a dialog ID to a documentation abstraction layer. The documentation abstraction layer maps the dialog ID to calls for obtaining help dialogs. The documentation abstraction layer generates a help call to a help service and the help service sends a help dialog to the client program. In this manner, the documentation abstraction layer facilitates updating help services without modification of the client program.
