converting the Physics Derivation Graph backend from JSON to a property graph

I shared the JSON database with a few researchers and realized I am embarrassed by the pointer chasing needed to construct the graph. The complexity of numerical IDs used for every feature in the PDG is confusing.
I had come up with a property graph schema which greatly simplifies the concepts and reduces the pointer chasing present in the JSON. Implementing the backend of the PDG as a property graph instead of JSON is a reasonable and beneficial task, but I'm not comfortable with any of the available property graph databases. There are many options available:
Staring at the current PDG JSON file, the structure is reasonably intuitive and relatively close to the property graph schema I had come up with. The JSON structure is not a "nodes and edges" design. The JSON is hierarchical (nested dictionaries) to both be more concise and to reduce the computational pointer chasing.
