Table Of Contents
l Page: 1 side of a physical paper sheet.
l Datapage: 1 atomic unit of content that produces zero, one or more pages.
l Document: group of 1 or more ordered datapages intended to the same recipient from the same source (ex:
invoice).
l Group: a logical and ordered group of documents (ex: all invoices for a specific customer number; all documents
going to the same address, etc.)
l Job: file that contains 1 or more groups.
When Metadata is produced for a given job, a hierarchical (i.e. tree-like) structure is created, composed of the above ele-
ments in the following order: Job->Group(s)->Document(s)->Datapage(s)->Page(s). Any operation that modifies the data
with regards to this structure (ex: remove pages, alter the data, etc.) makes the metadata obsolete and so it must be rec-
reated or refreshed.
As an example, consider the typical case of a PlanetPress Design document which uses a Line Printer datafile of transactional
data in order to generate PDF invoices for a series of clients. By using the Metadata tools available in PlanetPress Suite version
7, we can add the following information to the datafile:
l The job contains only invoices for clients located in Montreal.
l Since more than one invoice can go to the same recipient, invoices are grouped by customer.
l Each invoice is a document resulting from the execution of a PlanetPress Design document over one or more datap-
ages, which results in zero or more physical pages being output.
A single JOB can be composed of GROUPS of DOCUMENTS, which themselves are composed of physical PAGES produced by
executing a PlanetPress Design document on one or more DATAPAGES.
