Metadata elements
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:
l
Attribute: A read-only, system-defined element which holds certain information about a
certain node in 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 documents in a group).
Attributes are non-repetitive (i.e. name is unique) and do not persist through Metadata
recreation.
l
Field: A read-write, user-defined element which holds custom information about a certain
node in 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 has 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. This property is not visible in the
Metadata file, but it can be used in a Script task via the Metadata API.
Metadata attributes reference
The Metadata 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
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
dynamically, based on the content of the Metadata.
