Is there a good way to avoid having to write the

document:firstdoc#type@object_type:document

relationship in your example? I'd prefer not to have to write the relationship for every document object that gets created. It'd be nice to have an overarching tuple instead of duplicating that many times. I haven't thought through it much, but that's what I'm hoping for. If it's not possible it's no biggie, but it would be nice not to have to write a tuple per resource.
