Dgraph is our preferred underlying graph database written in Go. This document contains notes about how unigraph works with dgraph and some useful snippets to navigate the database.

We use a custom fork of dgraph which can be founded in the github organization.

• In our fork, we re-added the removed feature of predicate list, mostly for dynamical object support. Most data with defined schema can be accessed without it.

  "set": {
  "uid": "0xa4",
  "_value[": [
  {"_value": {"uid": "0x7a"}}
]
}
}```
