A condition can be added to a story (or inbox) frame; the associated event will only be executed if this condition is fulfilled. For now, the only supported condition is one based on a forecast published by the user. A condition must be specified according to:

• Type type must be equal to "Forecastforecast",
• ColumnId columnId is a reference to a column in the forecast table (see below), usually a parameter,
• RowId rowId is a reference to a row in the forecast table (see below), usually a location,
• Operator operator is one of "lt" (less than), "gt" (greater than), "le" (less than or equal to), or "ge" (greater than or equal to), and
• Value value is the reference value to compare to.

An example in which a condition is used:

<Frame><frame>
   <Title>condition<title>condition example</Title>title>
   <Start<start date="2008-03-13" time="00:01:00"/>
   <Stop<stop date="2008-03-13" time="00:02:00"/>
   <Popup>true<<popup>true</Popup>popup>
   <Condition><condition>
      <Type>Forecast<<type>forecast</Type>type>
      <ColumnId>water<columnId>water_level</ColumnId>columnId>
      <RowId>Lowestoft<<rowId>Lowestoft</RowId>rowId>
      <Operator>ge<<operator>ge</Operator>operator>
      <Value>300<<value>300</Value>value>
   </Condition>condition>
   <File>emergency<file>emergency_telephone_call.txt</File>file>
</Frame>frame>

An event can be associated with a story frame by specifying the File file key. Depending on the file type, a suitable application is started for displaying the file (e.g. a pdf-file is displayed in Adobe Reader and the contents of a txt-file is displayed in a message dialog window). The File- file key has an optional language attribute lang that behaves the same as for the Title title keys.

Apart from a File file, an event for the story frame may also be a Message message. For such a message, no file has to be added to the scenario/script database. Instead, the contents of the message (a text string) can be specified directly in the script configuration. The Message message key takes an optional lang attribute as explained before.

The contents of the forecast table can be configured using the ForecastTable forecastTable key. The schema for this section is as follows:
