Integrity constraints in graph databases

What is it about?

One thing that is still being developed for graph databases is integrity constraint (IC) support. One possibility to IC proposal is to consider a graph conceptual schema and a graph database schema. At least inherent ICs coming from a graph conceptual schema should be considered as explicit ICs on the graph databases level, i.e., using a DDL. In the paper, we focus on graph database Neo4j and its possibilities to express a database schema and ICs. We extend these possibilities through new constructs in Neo4j DDL including their prototype implementation and experiments.
