Hello All,

Quoting Peter Saint-Andre <stpeter at stpeter.im>:

Are you really sure the separate element is needed for created collections?
With current structure it's already possible to differentiate "new"  
collections from the "old" ones by "version" attribute, so "created"  
seems to provide no extra information.

Besides of that what if collection was created and then changed, and  
after that replication takes place? With current approach it's just  
one "changed" item, but what should be sent when using "created"  
element? Two records? (one for "created" and one for "changed")? But  
"changed" element is already enough to know the fact that collection  
was created, so it's just an overhead. When client performs its first  
replication this "created" element would increase responce size by the  
factor of 2 (as every collection was created first and then in most  
cases changed later by adding messages there).

Overall that's not a huge problem, but to be frank I just do not see  
any real benefit from having separate "created" element, only some  

Good luck!                                     Alexander
