Using Online Collaboration and Annotations

FDF (Forms Data Format) is an Acrobat-specific format used to store form data and other 
information from a PDF file. An FDF file that is created during a comment upload contains 
only the reviewer’s comments and a reference to the reviewed PDF file. Consequently, the 
FDF file is typically more compact than the corresponding PDF file, and does not need to be 
stored under the same parent directory or even on the same machine. For more 
information about FDF, see the

PDF Reference.

FDF files can also contain JavaScript code that can be used to automatically configure the 
server preferences. For example, a user can navigate to an FDF file on a server and double-
click on it. Acrobat then executes the JavaScript code in the file, which automatically 
configures the server preferences for the user.

For online collaboration, Acrobat JavaScript provides several important capabilities:

●

Interface to a database — Acrobat JavaScript provides objects to interact with a 
database via ADBC (Acrobat Database Connectivity). Using JavaScript, you can read 
values from a database, update or insert new data, and delete information. See 

 for more information.

●

Set the comment repository preference — To use Acrobat’s collaborative review 
capabilities, you must specify the type of comment repository to be used, as well as its 
location. Those preferences can be set manually, or with Acrobat JavaScript placed in 
either the PDF document or its associated FDF file.

●

Interface to a web service — Acrobat JavaScript provides objects to interact with a web 
service via SOAP, which is an XML-based transport protocol used for exchanging 
information. Because it is the developer's choice as to which operations are performed 
by a given remote procedure, the Acrobat JavaScript SOAP support enables a more 
customized collaboration workflow. For more information, see 

.

You can extend the Acrobat Online Collaboration feature in several ways:

●

You can write JavaScript code to customize your review process and comment handling.

●

You can integrate Acrobat’s Online Collaboration feature into a larger document 
management system.

●

You can use Acrobat JavaScript to add additional annotations. 

●

Through the use of the Acrobat JavaScript SOAP object, you can customize the way that 
Acrobat handles annotations.

For more information, see the Acrobat JavaScript Scripting Guide and the Acrobat JavaScript 
Scripting Reference.
