Note
This task will automatically loop through the metadata and repeat its action for each of
your metadata's datapages. This task should not be placed after a Metadata Sequencer.
Input
Any data file with accompanying metadata.
Processing
Fields are added, removed, modified, etc, according to the actions defined in the task
properties. If the field is present in a level that repeats (for example, the data page level), this
task loops so that the action may take place on each of the occurrences of that level.
Updating all nodes
For a given Metadata Field Management action, all nodes of a given level mightbe updated
with a New Field value.To accommodate this, all metadata/data selection functions accept a
wildcard parameter "?", indicating the function operates on allnodes (not just one) of a given
level.See: "Data selections" on page25.
Limitations
l The name of the metadata field to add must adhere to these 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
.
Output
The original data file is outputted, along with the modified metadata.
