Released today, Neo4j 1.8.M03 introduces the RELATE clause, a two-step dance of MATCH or CREATE. Also, new Transaction support in the shell let's you call for a do-over in case you misstep. RELATE, a Subgraph Match-Maker A RELATE clause looks a lot like a MATCH clause — the ASCII-art of graph traversals — but behaves differently when there isn't a satisfying subgraph. When there is no

Our longer arcs of development are chunked up into short-term stories, which arrive with notable features at differing points. Uniquely, at this 1.8.M02 merge point, the changes are all of the strong, silent type: under-the-hood improvements, stage-setting additions, or simple issue-correcting. This is a solid, trustworthy release for anyone staying up-to-date with the leading edge of

Triggered by a user question, let me just very briefly highlight a nice and easy graph visualization feature. Sometimes, you just want to fast see what you are putting in your little example graph. In Neo4j, there is a well hidden gem-the Graphviz Component. To very shortly output a graphviz rendering, look at this test, demonstrating the basic usage (this code is actually taking a traversal

Neo4j 1.8 has an eye for expansive views, painting a picture with data and hanging it on the web. In this first milestone release, artful work on the Cypher query language is complemented with live views in the Neo4j documentation.

We’re very pleased to announce that Neo4j 1.7 GA, codenamed "Bastuträsk Bänk" is now generally available.

The full general release of Neo4j 1.7 is now in view, with this milestone marking feature completeness. This 1.7.M03 release is recommended for migrating your test servers, client applications and drivers in anticipation of 1.7.GA, since there will be no more visible API changes.

Over the last few days the Neo4j community team worked on the initial iteration for an interactive Neo4j tutorial. The first result we are proud to publish is a sharable console that runs an in-memory Neo4j instance in a web-session. It supports Cypher queries of the graph and Geoff for importing and modifying the graph data. The graph itself and the cypher results are visualized in an overlay

Hi all, repeatedly there are questions on how to set up Neo4j with Eclipse and the Maven integration for it . Here is the short version: First, choose to create a new maven project: Second, choose the default maven quickstart archetype for it: Now, after choosing a package namespace and project artifact id, wait for the project to created and go to the dependency tab of the pom.xml.

Hi all, Today, for my lab project, I decided to model an in-graph index in Neo4j and query it with the Cypher Query Language. The basic problem we try to solve here is the ordering of events in a timeline and asking for ranges of events ordered in time without needing to load the whole timeline, or let an external index like Lucene doing the sorting (which is very costly). So, a simple
