Client/Server Architecture
A multi-server setup where more then one PlanetPress Production server are connected as clients to a single PlanetPress Pro-
duction server which has a Capture Database. In this architecture, the Server contains the licenses for the pens, however the
Client contains the database of documents and patterns. The Clients communicate with the server to authenticate pens. This
architecture is only provided to simplify pen licensing for users with a large number of pens.
Closed Document
A document still within the PlanetPress Capture Database of which all the required fields have been filled by the Capture Field
Processor from a PGC. A closed document will only remain in the database until it is retrieved with the Get Capture Document
task, after which it is deleted.
Contamination
The act of writing on a "wrong" document, aka one that has a Pattern Sequence different that the one for which it was
produced.. This can happen in architectures with more than one sequence being used such as when a pen is docked in the
wrong location or if two pens are swapped.
ICR(Intelligent Character Recognition)
Recognizing text that has been hand-written with the Anoto Digital Pen. This feature is currently not implemented in Plan-
etPress Capture, but will be in the (near) future.
Ink Data
The pen stroke information contained within the PGC file. This is the actual data applied to the document (lines, signatures,
text, etc).
Open Document
A document in the Capture Database that does not yet have any ink data on it, or of which not all mandatory fields (or final
field) have ink present on them. Such a document is waiting for a new PGC file to complete it so it can be closed.
Pattern ID
The IDof the Anoto pattern. Represents the pattern on the page. Can be used to retrace the document to which the pattern
belong.
Pattern Sequence
Pattern Sequences enable the multiplication of the number of available pattern by adding an extra identification to the doc-
ument. A Pattern Sequence is also attributed to each Anoto Digital Pen, such as an incoming PGC file will contain the Pattern,
on which the Pattern Sequence is added from the pen database. The pattern and pattern sequence refer to a specific document
in the database. Signing a document with a pen of which the Pattern Sequence does not match that of the document causes
Contamination, which can cause errors or ink to be placed on the wrong document.
Pen ID
The serial number of the Anoto Digital Pen. It is registered in the PlanetPress Capture database and is present in each PGC file.
PGCFile
Pen Generated Coordinates; PGC File containing all ink processed while the pen was undocked along with the Pen ID. It is pos-
sible that a single document requires multiple PGC, just as it is possible that a single PGC have multiple documents.
