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26.
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.
Properties
General tab
l
Action: Select the type of Metadata Field Management action to perform. Five action
types are available:
l
Add/Replace: Create a new metadata field. If the name already exists, the value is
overwritten with the new one.
l
Duplicate: Create a new metadata field. If the field already exists, a new instance is
created.
l
Append: Append the new value at the end of the current one. If no field with that
name exists, a new one is created.
l
Sum: Calculate the sum of all values found inall fields of a given name, at a given
level. The resulting number is formatted by default with the dot decimal separator.
