Defining Default Attribute Sets
When the user does not specify an ATTRIBUTE parameter for a webject, the Windchill adapter returns the set of all attributes valid for the type instances in the output group.
You can configure the Windchill adapter to return a set of default attributes for certain types when no ATTRIBUTE parameter is specified for a webject. The form for specifying a default attribute set for a type is:
DefaultAttributes.type=attributeList
where type is the type of the type instances in the output group and attributeList is a comma-delimited list of logical attribute names valid for type.
In the following example, when WCTYPE|wt.part.WTPartUsageLink type instances are returned in an output group for a webject for which no ATTRIBUTE parameter is specified, the attributes quantity.amount and quantity.unit are included:
DefaultAttributes.WCTYPE|
wt.part.WTPartUsageLink=quantity.amount,quantity.unit
