[MonetDB-users] Discontinuation of MonetDB XQuery

Hello I am a MonetDB XQuery supporter ( http://permalink.gmane.org/gmane.comp.db.monetdb.user/3824) and I am sad that it is discontinued. I was very enthusiastic about the software so I was rather excepting an upgrade to MonetDB5. However I am confident that it will be easy to turn my application to MonetDB5. As a basic XQuery user, my questions are threefold: 1)Are there some explanations for this change (flaws in the design of XQuery 2.0, lack of users, performance limitation)? 2)Is MonetDB5 SQL able to store GB of data (as MonetDB XQuery)? Will we observe performance gains for (time ordered) one dimensional data? 3)Is there an equivalent to the XRPC API? Warm regards Ryad
