I am building a sync application between GData and another source, using Zend GData library.
While it is clear how to get the last update timestamp, I am not sure about the last updater. In order to decide whether I should sync the entry or not, I want to verify it wasn't me (the sync application) which updated it.
Looking at the Zend_Gdata_App_Entry there is both "Author" (which I guess is the original author, not the last one to updated), and "Contributors" (which I can't tell what it includes).
Looking at Google's documentation it seems any field can be updated, including the author, which I guess means it is not always the original author. It also seems to mean that there is no history/auditing about entry changes...
Does anyone has clear answer for that ?
