Metadata Level Creation
The Metadata Level Creation task conditionally creates new Metadata groups or documents.
This task is only functional if Metadata already exists for the current job.
For more information about Metadata see "Metadata" on page69.
The task enables users to merge data pages into Documents and/or merge Documents into
Groups, based on conditions. Unselected Data pages are ignored, but are moved with other
Data pages if the action is applied to the current parent node.
Using the wildcard parameter "?"
Since all metadata data pages, and possibly all physical data pages, are treated by the task at
run-time in order to evaluate the condition at each level, it is necessary to dynamically define
metadata as well as data selections to check all occurrences instead of a fixed one.
This is done using the wildcard parameter "?". When a question mark is used as a parameter in
a data or metadata function, the function operates on all nodes (not just one) of a given level.
Used in a rule, it indicates that a dynamic update of the current data page or level is required
before evaluating the condition.
For examples of how to use the wildcard parameter, see "Data selections" on page48.
Example of a process with the Metadata Level Creation task
Given a document input (created with Metadata), this task can be used to regroup the PDF
pages of the received print stream in logical (Metadata) documents, based on the keyword
“Page 1 of” printed on the pages, and then treat each newly created document individually in
the rest of the process
The process begins with the following tasks:
1. WinQueue Input: Intercepts a printed data file sent to a Windows printer queue.
2. Metadata Level Creation: Begins a new document node when “Page 1 of” is found on a
data page.
l Action: Document
l Delimiter: Begins when
l Rule: (@(?,1,1,1,9,KeepCase,NoTrim) IS EQUAL TO Page 1 of)
3. Metadata Sequencer: Splits the data file on each Metadata document node level.
