Cheers guys!<br><br>During my research of the way Google does stuff with their Gdata Protocol, I&#39;ve come across some decisions that have to be made (more like priorities - what should work first and what to improve later).
<br><br>First off - means of authentication. In order to use gdata, you need a google account (gmail counts as one). As an alternative, you can, upon invitation, view a document without having to log in (as stated 
<a href="http://docs.google.com/support/bin/answer.py?answer=47597&amp;topic=9378" target="_blank" onclick="return top.js.OpenExtLink(window,event,this)">here</a> ). That would be a good way of interaction with visitors who don&#39;t have editing permissions (as of yet I&#39;ve not found a way to send invitations using the API, but&nbsp; there should be one... I hope). Then comes the account part: 
<br><ul><li>A wiki can request that each editor use his own account to edit. That would mean:</li><ul><li>+ being able to collaboratively edit documents (the service allows for multi-user edit) &lt;still requires invitation&gt;
<br></li><li>- require a download to my account, edit, send back to wiki kind of work flow (much like download to desktop, edit, upload) !! I might be wrong on this, needs further research since there is the collaborative side of things !!
</li><li>more + / - to come (if anybody can think of other things to list here, please do)</li></ul><li>Any one wiki instance admin can create a google account and use it as a generic wiki acount. That would mean:</li><ul>
<li>- not being able to edit collaboratively (might not even be able to edit different documents at the same time - not sure if Google allows multiple log-ins per account)</li><li>+ edit in place</li><li>- limit of 200 spreadsheets / 5000 documents or images per account (would be ok for a small to medium sized wiki, but a larger one would seriously suffer especially when it comes to spreadsheets)
</li><li>more + / - to come (again, any ideas are welcome additions to the general picture)<br></li></ul></ul>I&#39;d like to take this occasion to ask you, the devs (and users) of xwiki what you would like to see from Google Docs Integration (prioritize). I&#39;d really appreciate knowing what the expectations are. Also, any upsides or downsides to the issue of authentication are welcome into discussion .
<br><br>Another issue is the fact that the gdata api provided by google will have to be integrated into the xwiki trunk (I&#39;d like to know how this should be done).<br><br>If possible, take some time to read the references bellow and others related, and comment upon what should be done and how.
<br><br>Thank you for your time and patience,<br>Radu Danciu<br><br>References:<br><a href="http://docs.google.com/support/bin/answer.py?answer=47597&amp;topic=9378" target="_blank" onclick="return top.js.OpenExtLink(window,event,this)">
