Specifying Property Information

Specifying Property Information

To specify property information in an IMDF file, use the Property element. You can

include as many Property nodes in an IMDF file as you want. Property nodes can be

children of the root node, a Device node, or a Videoformat node. Property nodes can

also be children of Section nodes.

Note Property nodes that are children of the root node affect all devices accessed

through the adaptor. Property nodes that are children of a Device or VideoFormat

node affect only that device or video format.

You use attributes of the Property element to specify characteristics of the property,

such as its name, type, and constraints. For more information about Property

attributes, see “Specifying Property Element Attributes” on page 7-14.

The following example outlines how to use these elements to specify property

information. The example shows the Property node as a child of the root node but you

use it the same way as a child of a Device or VideoFormat node. The words in italics

represent text you define.

<Property constraint=constraint_value

deviceSpecific=true_or_false

readOnly=always_never_or_whileRunning
