Capturing and Archiving
After the printed documents have been inked with the Anoto Digital Pen, the PGCfiles from the
pen must be processed and merged with the appropriate documents in the PlanetPress
Capture Database. Aworkflow process that receives PGCfiles and reads them in turn consists
of the following actions:
l An "HTTP Server Input" on page228 task or "Folder Capture" on page213 task that
receives the PGC.
l The "Capture Fields Processor" on page486, which converts each PGCin an EPSlayer,
adds this layer to the PDFin the database, releases patterns and closes documents.
l Optionally, a "Capture Condition" on page476 task to do post-processing using the
Capture Fields data.
l A"Get Capture Document" on page502 action task to retrieve each document in the
database and output a PDFfile
l Any existing output such as Output to Folder, email, ftp, etc.
Technical
Because of timeout limitations, it is generally a good idea to use the Send immediate
response to clientoption of the HTTPServer Input task, especially when processing a
large amount of documents from the pen. Additionally, HTTPServer Processes should
always be self-replicating and have a short polling interval set in their properties.
Managing and Post-Processing
There are a couple of things that can be done even after documents have been inked. As long
as a document remains open, it is still present in the Capture database and be used in a
process:
l The "Find Capture Documents" on page497 input task is used to retrieve a list of
documents under specific criteria.
l
The Capture Condition and Get Capture Document tasks are used to effect post-
processing and retrieve document from the Capture database.
