I started out using orientdb/pyorient to store hashtags and what hashtags they were related to. I got the point where I was storing the hashtags and then I needed to create the edges. I then realized that to do this, there would be a lot of redundant data. Each tag would have to be stored again as an edge to each tag it's related to.
I then discovered hypergraphs. I have found halp which seems more standalone than something like orientdb. I don't think it has storage either. My question is, are there any well supported graph engines that can make these relationships without storing redundant data and have a python library?
