I wonder if we actually need something like that (we have an activity
object where we could put it) or if it's better to just let the activity
author decide when saving/loading is necessary, using the TextObject stuff
I proposed.

It feels a bit inflexible to have the activity request read/writes so
directly. I'd rather have notification that the activity is closing, then
the activity author decides what needs to be done.

Yes. Can we just mirror the datastore dbus interface there?

function onFound(objectIds) {
}

datastore.find(query, properties, onFound);

I have no idea what query/properties contains but I suppose it's documented
somewhere :)

I suppose we will also need a datastore.delete.

 Can you explain the use case for these?

Thanks for the feedback!
