7.2

For a given Metadata Field Management action, all nodes of a given level mightbe updated with a new Field Value.To accom-
modate this,metadata/data selection functions have beenmodified to accept a wild card parameter "?", indicating the function
operates on allnodes (not just one) of a given level.For example, in a PDF emulation, the format of a selected region is:
region(?,0.59375,2.21875,1.85416,2.51041,KeepCase,NoTrim)
where “?” represents the current physical data page processed by the task.
Limitations
l The name of the metadata field to add must adhere to thess syntax rules: start with a letter, followed by zero or more
letters, numbers, underscore or dash. The name is not case-sensitive.
l Metadata Fields Management actions on the Page level are not possible since the entire task execution is based on the
data page node.
l The task raises an error if the selected Metadata Fields Management action is Sum and if one of the field valuesis not
numeric.The task supports approximately 15 digits of precision in a range from 2.23 x 10
-308
to 1.79 x 10
308
.
Metadata Filter Action Task Properties
The task allows specifying the Level (Group, Document and Datapage) on which to perform the action and under which con-
dition. At least one level must have the condition set. The action will be performed sequentially beginning with the rule on the
Group level, Document level and Data page level. The selection is performed on the node only.
Metadata Filter task properties are as follows:
General Tab
l Filter levels: Rules for unselecting nodes at the Group, Document or Data page level. Note that currently
unselectednodesare ignored.
l Group: Select the metadata Group nodes (the nodes only) based on the specified rule(s).
l Document: Select the metadata Document nodes (the nodes only) based on the specified rule(s).
l Datapage: Select the metadata Datapage nodes (the nodes only) based on the specified rule(s).
l Rules: Define according to which criteria the action must to be performed. The condition must be TRUE to execute the
action. All nodes on a specific level with false condition become Unselected. The task effectively both selects and unse-
lects nodes based on the condition. To set up conditions, the Rule Interface is displayed, allowing to edit the condition
for the given action. See the"Rule Interface" (page 160) page for more details.
l Select all metadata nodes: Check to reset the Selection status of all nodes before performing the filtering, effec-
tively selecting all metadata nodes. This basically undoes the work of any previous Metadata Filter or Metadata
Sequencer, so please be careful when using this option.
On Error Tab
The On Error Tab is common to all tasks. Details can be found on "Task Properties Dialog" (page 53).
Special Considerations
l The task CANNOT re-select unselected nodes if the condition is false for those nodes.
l Filter rules cannot be based on the following metadata attributes: SelectedIndexInJob, SelectedIndexInGroup, Select-
edIndexInDocument and SelectedIndex.
Metadata Level Creation Action Task Properties
Conditionally create new metadata groups or documents. This task is only functional if metadata already exists for the current
job.
