PlanetPress Capture Glossary

This topic describes the specific terms used in the PlanetPress Capture set of tools within OL Connect Workflow.

Anoto Digital Pen

A digital pen compatible with the Anoto system. These pens contain a camera, processor and memory chip which record each stroke of the pen on a printed Anoto Pattern, and are able to send this information back to OL Connect Workflow. This document specifically refers to the Anoto DP-201 Digital Pen, not other equipment has been tested.

Anoto Functionality Statement

Statement ('Paper featuring Anoto functionnality') that is automatically placed on the page when a PlanetPress Capture field is present. The statement can also include the Trace Code

Anoto Pattern

A series of dots placed in a pattern that is unique to each page where the pattern is printed. The Anoto Digital Pen identifies this pattern and its location on the page. PlanetPress Capture contains 20,000 patterns (8 in demo mode, See PlanetPress Capture License Management) which can be used to generate documents.

Capture Condition

OL Connect Workflow task that is used for post-processing of documents after they have been processed by the Capture Fields Processor. Conditions can be made on the document status or the presence (or absence) of ink on any of the Capture Fields on the document.

Capture-Ready Document

A PlanetPress Design document (*.pp7) that contains at least one Capture Field on at least one page.

Capture Document Manager

A tool that lets a user search through the available documents in the Capture Database. The documents can be search through a few different criteria and can be displayed as PDF files, individually or as a group. Documents can also be closed or deleted from this interface.

Capture Field

The object that acts as a placeholder for the Anoto Pattern. The pattern is only applied when using the Capture Field Generator in Workflow.

Client/Server Architecture

A multi-server setup where more then one OL Connect Workflow server are connected as clients to a single OL Connect Workflow 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 PlanetPress 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 document. 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 possible that a single document requires multiple PGC, just as it is possible that a single PGC have multiple documents.

Pidget

Type of PlanetPress Capture object. Page element used to give instructions to the Anoto pen, as opposed to recording ink.

PlanetPress Capture Database

A database containing the list of patterns, sequences, registered pens and documents. The Capture Database can be used by a single server, or by multiple servers in a Client/Server architecture.

Session

The time spent by the pen between events that trigger a new session. Generally a session refers to any ink in a single page containing a Capture Pattern. A session can contain ink from multiple fields in any order. A new session starts whenever a PGC is sent for processing (which erases the data from the pen).
