+1 For another data point, Alastair Green, also of Neo4j, was here at Uber last week to align on property graph standardization. This was just before the thread on universal structure / algebraic property graphs. He was open to using APG as a high-level data model from which the property graph standard (which will be implemented by Neo4j) can be derived by adding constraints. Jan Hidders, Ryan Wisnesky, and I have been working on a set-based formulation of the model which should enable this. If Neo4j is to be the reference implementation for TP4 property graphs, then it will be good to have Dimitry in the loop w.r.t. the data modeling discussions, as well.
