WDialog is an advanced system to create dialog-centric web
applications.
Feature list:
- Separation of the user interface (UI) definition
from the backend program, improving the structure of
the application and enabling advanced software
engineering processes
- The UI definition is contained in an XML file, and
it describes the whole UI from the overall dialog
structure to the style of the individual HTML element
- The dialogs have built-in persistency for session
state. The HTML form elements can be tied to dialog
variables reflecting their current state
- A powerful template system manages the combination of
individual HTML fragments to whole pages
- The dialogs behave like GUI widgets. They visualize the
state of the session, and user clicks are treated like
events that are handled by programmable callback methods
- The callbacks are written in a real programming language
(Objective Caml, or Perl), making it possible to formulate
all algorithms and to use all system resources
- The application can run as CGI as well as application
server
- The WDialog toolkit itself does not require any database
as backend store
- WDialog preprocesses all web inputs, and ensures that
minimum security standards are fulfilled
