Neo4j comes as stand-alone server accessible via an REST API. You can add other API's on top of the embedded Graph Database yourself by using Plugins / Extensions. > 2.

I say - OK, let it What lib are you referring to? A client library? (this one? https://github.com/neo4j/java-rest-binding) There are REST clients for many languages and it is fairly easy to write your own. Still, the solution that is most flexible and performant is either to embed neo4j and expose domain protocol endpoints in your own server or write a server plugin/extension that provides those. > be.

Each HTTP request is a single transaction. Other approaches that handles transaction over the wire individually and longer running are planned. > Am I missing something? > I hope I do, because in this situation, Neo4j isn't actually interesting DB > server/solution...but I want it to be. I would like to know some more detailed reasons for that, so far we haven't received this kind of response.
