Oh, I see. Clicking on the export links in the browser works without
authentication, but issuing the queries directly doesn't yet. No good reason
for that, so I'll get it changed.

Yes. I already answered this twice already.

Mostly. There's a "Plain Text" format that doesn't include any
relationships, and the other formats differ slightly in how they represent
one-to-many relationships, but the logical structures are the same.

But to be clear, this is not my goal. Needle makes no claims to be a Linked
Data brand system. It is HTTP/REST-based, it is a graph database, and every
node does have an ID (and by virtue of this a URI), but linking is not our
primary concern. You're actually the one who brought Needle into this
conversation, not me. Ironic, given your short temper about people derailing
"your" threads.
