Bug ID: 343852
Summary: okular's pdf form data isn't compliant with the
standard FDF format, which results in severe pdf
usability problems
Product: okular
Version: unspecified
Platform: Other
OS: FreeBSD
Status: UNCONFIRMED
Severity: major
Priority: NOR
Component: PDF backend
Assignee: okular-devel@kde.org
Reporter: y...@tsoft.com
Currently forms data is stored in some XML files located away from the pdf
file: ~/.kde4/share/apps/okular/docdata/299074.<pdf-file-name>.pdf.xml
There is the standard for the form field data defined in section "8.6.6 Forms
Data Format" of PDF reference:
http://partners.adobe.com/public/developer/en/pdf/PDFReference16.pdf
In short, field data by default should be embedded in the pdf file itself. User
can also export (or extract) it into the separate .fdf file, that can be stored
separately. FSF is just the directory-style format, defined in the same fashion
as the pdf format itself.
Current implementation doesn't follow this standard, and doesn't store the data
with the document. Forms data becomes not portable, and it is
difficult/impossible to keep several versions of the filled form.
In short, the way how forms are currently implemented is barely usable, and
prone to user confusion and accidental data loss. (!!! Why forms data dies when
user deletes ~/.kde4 ? !!!) One can fill the form and print it, but people
can't keep backup copies or send filled document to others.
Anybody experienced with pdf forms will have a problem with the current
implementation.
This is the major usability problem.
Reproducible: Always
