/*
Space represents a space.
There isn't a one-solves-all hierarchical data structure for DBs,
so for now we are using a mix of materialized paths and adjacency list.
Every space stores its parent, and a space's path (and aliases) is stored in a separate table.
PRO: Quick lookup of childs, quick lookup based on fqdn (apis).
CON: we require a separate table.
