Dear all, I've probably overlooked this in the docs but asking for confirmation. Does db:add multiple resources to the same path guarantee sorting based on insertion time? If yes, then maybe I could add a note about this in the docs? Thanks, Marco.

Sorry for the late reply, but I’m not sure if I understand your question. It’s correct, it’s possible to add multiple resources to the same path, e.g. as follows:
for $i in 1 to 100
return db:add('db', <a/>, 'a.xml')
There’s no need to do any sorts, as the target path is identical. All resources will simply be attached to the database storage. Or did you question yourself if sorting is some necessary when resources are requested in a later step? Ciao, Christian

Hi Christian, sorry for not being clear enough. I was just wondering whether I can rely on insertion order being kept when I perform a corresponding db:get("db", "a.xml"). In other words given your slightly modified example:
for $i in 1 to 100
return db:add('db', <a x="{$i}"/>, 'a.xml')
Will
db:get('db','a.xml')
always return (<a x="1"/>, <a x="2"/>, ...<a x="100"/>) M.
