Each chunk created by the Metadata Sequencer Action task is called a "sequence". The properties of each sequence determine
how many sequences will occur and what each sequence contains.
Metadata Sequencer task properties are as follows:
General Tab
l Metadata level: Select the metadata level to process.
l Sequencing is based on...:
l The following number of occurrences of the level: Determine a sequence based on the number of
instances found for the metadata level currently processed. For example, if the Metadata level is set to Group,
and this value is set to 3, each sequence contains 3 groups (except, possibly, the last one, depending on the
number of groups left in the last sequence). The next loop starts with the next group after this sequence.
l Thefollowing number of sequences in the job:Divides the metadata into a set number of sequences
and equally distributes the number of levels between the sequences. For example, it the Metadata level is set to
Document, and this value is set to 5, a 100 document job file will be divided into 5 sequences of 20 documents
each.
l Thefollowing rule: Determine if a new sequence starts or if the current one ends. For each metadata level,
the current value of the specified metadata attribute/field is compared with the one in memory. If they are dif-
ferent, either a new sequence starts or the current sequence is ended. The next sequence starts with the next
metadata level being processed. For details see the "Rule Interface" (page 201).
Metadata Sorter
The Metadata Sorter Action task allows metadata to be sorted sequentially on three different levels, alphabetically or numer-
ically. It also allows sorting in ascending and descending order.
Metadata Sorter task properties are as follows:
General Tab
l Group:Sorts the metadata by group.
l Document:Sorts the metadata by document.
l Data page:Sorts the metadata by data page.
For each parameter, three columns are available:Sort By, Then by, Then by (again). This lets you sort your document level in
three different orders sequentially. Sorts are always done from left to right, top to bottom, giving you a total of 9 sorting pos-
sibilities.
When you click on either of the sort boxes, a small popup displays the following options:
l Sort by:The drop down displays a list of available fields and attributes in that level, letting you select on which to sort.
The field or attributes must be present for every instance of the level you are searching on, or the task raises an error.
l Order:Choose Ascending (orders like a,b,c, or 1,2,3) or Descending (orders like 3,2,1 or c,b,a) order. If the Numeric
sorting option is not checked, numbers are sorted like this:"1, 10, 11, 12, 2, 3, 4, 5, 6, 7, 8, 9".
l Numeric Sorting:Check to sort numerically instead of alphabetically (only supports whole numbers. Currency with
thousands separator and decimal points will not work). If any non-numeric value is found in the field or attribute, in any
instance of the level, the task raises an error.
On Error Tab
The On Error Tab is common to all tasks. Details can be found on "Task Properties Dialog" (page 54).
