Each metadata node (i.e. Job, Group, Document, etc.) is described with a series of elements, that is, system-defined attributes
or user-defined fields holding static or dynamic information about the node they are attached to. Each element has a name and
a value. More specifically, here is a definition of these 2 types of elements:
Attribute: A read-only, system-defined element which holds a certain information about a certain node from the Metadata
structure. This information can be static (e.g. the size of a physical page) or evaluated on-the-fly (e.g. the number of doc-
uments in a group). Attributes are non-repetitive (i.e. name is unique) and does not persist through metadata recreation.
Field: A read-write, user-defined element which hold custom information about a certain node from the metadata structure.
Fields are repetitive (i.e. the same field may appear multiple times) and persist through metadata recreation.
In addition to attributes and fields, each node of type group, document or datapage have a boolean property called selected
that indicates whether or not to produce the pages under that node. By default, this property is set to true for all nodes.
Metadata Attributes Reference
Here is a description of the Metadata attributes. The attributes are categorized as either Production, Finishing or Index/Count.
Production attributes describe the production of the job and/or metadata (e.g. path and name of the datafile, date at which
metadata was created, etc.)
Finishing attributes describe the finishing intent (e.g. page dimensions, page orientation, duplex mode, etc.). Note that the
presence of some finishing attributes depends on the PlanetPress Design document and target device used when producing
the job.
Index/Count attributes are not part of the original metadata file. They are evaluated live based on the content of the metadata.
In the following table, the last 5 columns indicate at which level the corresponding attribute is available.
Attribute Description Category Job Group Document Datapage Page
DataEncoding (optional) Name of the character encoding. Production X X X
DataFile
(optional) Path and name of the data file used by the PlanetPress
Design Document.
Production X X X
Date Date the metadata was created in ISO format. Production X X X
Time Time the metadata was created in ISO format. Production X X X
Title Title of the source document. Production X X X
Producer Name of the sofware that created the metadata. Production X X X
Creator Name of the software that created the source of the metadata. Production X X X
TargetDevice
Name of the device for which the metadata and associated data is
intended.

Dimension
Two floats separated by a colon indicating the media size in typo-
graphical points (ex: 612:792).
Finishing X X X X X
Orientation
"Rotate0", "Rotate90", "Rotate180" or "Rotate270", indicating
respectively portrait, landscape, rotated portrait and rotated land-
scape.
Finishing X X X X X
Side
"Front" or "Back"; indicate whether the page is on the front or the
back of the paper sheet. This attribute is a "best effort" and is
device-dependent.
Finishing X
Duplex
"None", "DuplexTumble" or "DuplexNoTumble"; indicate a change
of the duplex status.
