File version comparison with AVM

[mariostriglione]

Hi everybody.
This is my first post in this forum.

I am using the alfresco WCM, I have a question about AVM.
Reading the WCM_Overview wiki page:

In addition to these extended versioning operations, the AVM also supports the following capabilities:
File version comparison
Between two file versions on the same branch within a single repository
Between two file versions on different branches within the same repository
Between two file versions between any two repositories

Using the AVM features I would like to browse the differences between two versions of the same web document (an HTML page) but I do not understand how to setup WCM projects in order to support AVM and file comparison between versions. I have not found any AVM reference in the alfresco client. Is there any procedure to follow or operation to execute?

Best regards.

While the AVM supports these kinds of features, they're not yet exposed via the Web Client UI.  Instead you might develop a UI Web Script (see http://wiki.alfresco.com/wiki/Web_Scripts for details) that allows the user to select two AVM nodes, and then uses the AVMSyncService (http://dev.alfresco.com/resource/docs/java/repository/org/alfresco/service/cmr/avmsync/AVMSyncServic...) to compare them.

Cheers,
Peter

Thank you pmonks, i'll try it with web script

One thing to note - the AVMSyncService is primarily designed to generate diffs between directory trees rather than create sub-file level diffs, so depending on what you're trying to do it may not be enough by itself.

Cheers,
