| <section name="SCXML documents to describe Shale dialogs"> |
| |
| <p><a href="http://shale.apache.org/">Shale</a> is |
| "<i>a modern web application framework, fundamentaly |
| based on JavaServer Faces</i>". The Shale Framework includes a Dialog |
| Manager, to describe "conversations" or "dialogs" |
| (involving multiple views) with the user. Such a dialog is described |
| using a state-machine like declarative notation defined by the Shale |
| Framework. An alternative is using SCXML to describe the Shale dialogs |
| by introducing a <code>DialogNavigationHandler</code> that uses the |
| Commons SCXML engine. |
| </p> |
| |
| <subsection name="Motivation"> |
| <ul> |
| <li>SCXML semantics support parallelism, allowing multiple dialogs |
| to execute at the same time (a.k.a regions), and interact with each |
| other. This will be useful as Shale Dialog Managers evolve.</li> |
| <li>The Commons SCXML implementation allows for registering listeners |
| that get notified as the state machine executes (onentry, onexit, |
| ontransition).</li> |
| <li>Those developing multi-channel applications, or using frameworks |
| that use SCXML for the controller bits in other contexts (e.g. |
| RDC framework), may be inclined towards SCXML-based authoring for Shale |
| dialogs.</li> |
| </ul> |
