Re: Introduction

Hello bergi,

And welcome here! I am Niko, the author of NextGraph.org maybe you heard 
about it recently.

I am glad you have an interest for distributed datasets and that you 
implemented something similar to an append-only log of changes for RDF. 
And the format is similar to what NextGraph is doing, as I could see. 
you use a set of added quads and a set of deleted quads for each change.

In your repo, you write "Any conflicts of previously added/deleted quads 
in the same changeset are solved."

I didn't have time to read your code to find out how the conflict 
resolution is done.
Could you detail it for us ? It is an important detail if we want to 
understand if you solution is a CRDT.

Cheers,
Niko
