Subject: Category Nodes and Type Safety vs Perfo
Hi Guys,
We currently thinking of how we can get type safety when we do queries, one
thing we do is have a category nodes, so e.g.
Here is a sample query
IEnumerable list =
g.v(0).outE[[label:'HOSTS']].inV[[Key:'MyCompanyName']].inE[[label:'IS_COMPANY']].inV
So the part highlighted in b

Hello everyone, could you advice on the best way to do the following in neo4j?
Given:
- a graph G= on which each node has an associated positive cost
- a subset of "source" nodes S in E.
I'd like to build a second graph in which each e in (S-E) is connected

Hi Nolan,
I think I can answer a few of your questions. Firstly, some background. The
graph model of the OSM data is based largely on the XML formated OSM
documents, and there you will find 'nodes', 'ways', 'relations' and 'tags'
each as their own xml-tag, and as a consequence each will also have
According to the neo4j-sh help, there is a -c option to the trav command
that should allow for executing the ls command on each node visited in a
traversal.
-c Command to run for each returned node. Use $i for
node/relationship id, example:
-c "ls -f name $i". Multiple commands can b
Fortunately, recent changes seem to have made the memory leaks I was

The EmbeddedGraphDatabase is fine for production use - in fact it's the default
choice!
Hello,
I plan to use Neo4J for a Ruby on Rails web app. However, I have not the
possibility to use JRuby.
Due to doubts of performance issues using the REST API, I'm considering to use
the embedded graph database with means of
the Ruby Java Bridge (RJB). The Ruby app then would talk to the J
I have downloaded neo4-rest-graphdb, a rest wrapper for Java.
README file says this interface does not support transactions. So we have:
