After reading Why I'm Frequently Absent from Open Source by James Long and listening the corresponding The Changelog episode, I dwelt on the idea and believe that open source maintainers...

• ... should never be ashamed if they don't have time for a project.
• ... should be honest with themselves and open with their users so that everybody can be on the same page
• ... are people and they have at one time or another responsibilities or hardships that they need to attend to which reasonably take them away from a project
• ... may also reasonbly decide that they don't like the direction of a project or that they would like to explore other things and may leave a project permanently.

Along this line of thinking I've created a set of descriptions for different levels at which a project might be maintained. A maintainer can use these to announce to their users the current ability that they have to dedicate to a pr

Welcome to the Gitter channel for the Neo4j.rb project (the neo4j, neo4j-core, and neo4j-rake_tasks gems)

• Our official documentation is on http://neo4jrb.readthedocs.org
• If you have a question, ask away! If we aren't around this is the best way that we can get you an answer quickly.
• If you’ve found a bug, please provide steps to reproduce it and the versions of the gems you are using.
• Keep in mind that all contributors to the Neo4j.rb project are working on it in their free time. We are not part of Neo Technology (the makers of Neo4j)

Background:

The neo4j / neo4j-core gems were originally created by @andreasronge as a way to connect to Neo4j in embedded mode via jRuby. Since version 3.0 of the gem (Sept 2014), it is possible (and probably most common) to connect via Neo4j's HTTP endpoints in server mode. Support for Neo4j's binary protocol ("Bolt") is planned for version 8.0 of neo4j and 7.0 of neo4j-core.

You can, of course, just execute a Cypher query:

session = Neo4j::Session.open(:server_db, 'http://neo4j:password@localhost:7474')

result = session.query("MATCH (p:Person {uuid: {uuid}})-[r:LIKES]->(f:Food) RETURN p, r, f", uuid: 1234)

# First result
result[0].p # Person
result[0].r # `LIKES` Relationship
