Hi, this approach is followed by many users when they need a lightweight way to create relationships. For such reason we'd like to introduce mono-directional edges in 2.0, because all the edges now are always bi-directional. With mono-directional edge, under the hood will be identical to have a LINK (documentdb api), but at least you remain at GraphDB API level.
