PDF viewing and collaboration accross mobile devices


We are looking at using your SDK for an android app that will be used by schools to distribute PDF notes, homework etc. We would like to provide annotation (keyboard + pen) features. From the features list I think that this is possible but I would like to confirm and find out if the annotations are saved back to the PDF or a separate XML file. Reason for asking is that we would like to backup all annotations without necessarily backing up the entire PDF over wifi/3G


PDFNet has extensive annotation support, and annotations can be saved back to the PDF or be exported as a separate FDF or XFDF file. XFDF (XML Forms Data Format) is a format for representing forms data and annotations in a PDF document. It is the XML version of Forms Data Format (FDF), a simplified version of PDF for representing forms data and annotations.
