Last week I spend some time on implementing the Blueprints interface on top of Datomic. The RDF and SPARQL feel of the Datomic data model and query approach makes it a good target for implementing a property graph. I finished the implementation and all unit tests are passing. Now, what makes it really cool is that it is the only distributed “temporal” graph database that I’m aware of. It allows to perform queries against a version of the graph in the past.
This is the first solution I’m reading about addressing the time dimension in a graph model.
