[Neo4j] Populating a RelationshipExpander
Hi, How could I populate a RelationshipExpander directly with RelationshipType[] & Direction[] propertys. As the Traversal.expanderForTypes takes varargs, How can I do something along the lines of below or should I implement an Expander?

[Neo4j] Add to Index REST API Question
Hi, I have a .Net application that makes heavy use of entities (nodes) and relationships between them. I am currently using a SQL database to manage this, but I know it won't scale the way I need it to, so I am looking to implement Neo4j as a solution. I am using the server and REST APIs and I've been able to create nodes, relationships, and properties with no problems. I have a couple of questions: 1) Since I will keep the SQL database as part of my app to store and manage other data elements (including some properties associated with the entities that will be in the neo4j db) is it better to: (A) add the neo4j node.Id value to my SQL database to use as a lookup when getting neo4j nodes, or (B) add a property to each node (i.e. an identifier from the SQL db associated with the entity/node), index it in neo4j, and then search/retrieve nodes by their property value? 2) My initial answer to question #1 was (B) and I have been trying to figure out the indexing functionality in neo4j but have hit a wall. I keep getting 404 errors when attempting to add a node to the index. I haven't been able to get the cURL command ( http://components.neo4j.org/neo4j-server/1.3.M02/rest.html#Add_to_index) to work either. Am I approaching this wrong? Any tips from anyone using the indexing REST API from .Net? I am running 1.3.M03. Thanks, Kevin ___ Neo4j mailing list User@lists.neo4j.org https://lists.neo4j.org/mailman/listinfo/user

Re: [Neo4j] Connecting 2 separate graphs
Hi Hemant, > I thought Rexter project under tinkerpop would be a good home for things like > this since it is using blueprints and any graph engine that supports > blueprints should be able to connect with another blueprint enabled graph > (both neo4j in my case). Another possibility is if both graphs were indexed > for the common node types then they can be referenced independent of the > graph they come from. Any other ideas/suggestions/comments? Rexster allows you to wrap any Blueprints-enabled graph (thus, graph database, RDF store) and expose it over HTTP as a RESTful service using Grizzly standalone webserver or through Tomcat. Rexster supports any number of graphs exposed through the same service. E.g. http://localhost/graph1/ http://localhost/graph2/ For your problem, you want to expose two different graphs, but I assume you want them on different machines. If this is the case, I wouldn't worry so much about which web wrapper to use as to your data architecture. Your model seems to fall into place with the Web of Data (Linked Data) paradigm. http://linkeddata.org/ ... With this model, you connect isolated graphs by using an URI scheme for the unique identifiers of your elements. Thus, the ids of your vertices denotes their physical location. As such, you can merge two graphs (and traverse over two graphs) where the only overlap of data is the point of merger. Graph1 machine: http://localhost/graph1/vertex/1 --- knows ---> http://removehost/graph2/vertex/2 Graph2 machine: http://removehost/graph2/vertex/2 --- worksFor --> http://remotehost/graph2/vertex/3 So forth and so on. There is much on the Web of Data so you could steal some design choices from them. Here is a short paper that is relatively easy to consume and explains the basics of the Web of Data architecture: http://arxiv.org/abs/0908.0373 If you find your mind attracted to this idea, then you might want to move more into RDF as you can use Blueprints Sail [ https://github.com/tinkerpop/blueprints/wiki/Sail-Ouplementation ] and Gremlin to do stuff like this: https://github.com/tinkerpop/gremlin/wiki/LinkedData-Sail Thus, search your Web of Data as if its a single repository --- a single graph. Finally, the reason I say RDF is because you may find it cumbersome to deal with indices in graph databases using this distributed data model. In RDF, there is no such thing as an index as everything is directly addressable by its URI (even literals). In the end, its up to you... feel free to ask more questions.

Re: [Neo4j] shortestPath exception
Me and Cesar have been communicating offline because transferring of files
can be troublesome on the list. This error was producable with both 1.2 and
latest 1.3 SNAPSHOT builds. But Cesar was kind enough to send me his data
set and I was able to reproduce it, I've created a fix for it (just a minor
bug in the construction of the paths from the result set).
So this problem is fixed in the latest snapshot, but unfortunately couldn't
make it into the M04 milestone (released today or tomorrow). Are you OK with
trying out the 1.3 SNAPSHOT version for this? (should be available within an
hour or two).

[Neo4j] Strange graph results
Hi all, I'm still new to neo4j but I feel I get more used to it and I like that feeling, anyway I'm getting strange results, at least they seems strange to me but I bet they've a pretty easy explanation. The nice pictures below (thanks Andreas neoclipse rocks!) show what I got in a part of my db: http://dl.dropbox.com/u/22802242/nodes.png Personal informations has been obfuscated to not irritate anyone but you can see the yellow node is an operator who has "enabled" a user and assigned a password to another one, the two obfuscated grey boxes. As you can see the two operations has been produced from the same IP (172.18.1.34) and on the same day (129582360 which is 24/Jan/2011) The operator is also a user so he has relation with userFactory. What doesn't convince me are the two IP nodes, I (don't know why) expected to see a single IP node with more then one relation, one for PASSWORD_ASSIGNED_FROM and one for HAS_ENABLED_FROM For the sake of completeness I index every single IP, uid, network, etc... and check for presence before creating a new Node.

Matej, if you want to just write a Gephi file to the file system, you could do that with a simple plugin that you can trigger.

Hi Matěj, Neo4j has traditionally been an embedded database, so if you just want to host it in an existing application (e.g. in a Web app you already run on an app server) then that's probably a good choice.

My question is if it's possible to write this application like plugin (write another services) for Neo4j server or better approach is to run it on some application server.

Re: [Neo4j] doInternalRecovery takes a long time
J2SE 5.0 reached its End of Service Life (EOSL) on November 3, 2009, which is the date of the final publicly available update of version 5.0 (J2SE 5.0 Update 22). See: http://www.oracle.com/technetwork/java/javase/downloads/index-jdk5-jsp-142662.html We have decided to not support a JDK that is no longer supported by the JDK vendor. Compiling our code with the class file version set to 1.6 is our way to *strongly* urge you to move to JDK 1.6, which in every way is a better JDK. If you for some reason still need to use JDK 1.5, you could build your own, unsupported, Neo4j version. It should be possible to compile Neo4j using JDK 1.6 but setting the target version to 1.5. Most of the strict 1.6 dependencies are compile-time only. There might be a few runtime dependencies on 1.5, but those are probably limited to java.util.Deque and java.util.concurrent.TimeUnit. Your other option is to get a payed JDK 1.5 support contract for Neo4j from Neo Technology.

Re: [Neo4j] Using Data tab of Web-Admin to Delete Relationships
Hey Neal, I just looked into this, and you are absolutely right. The data browser uses an older method of removing relationships that is no longer supported by the underlying javascript neo4j client we use, and there was no test in place to ensure this feature works. I've fixed this, and written a test to make sure it doesn't happen again. I'll push this in to be available in the 1.3 M04 release that will be released later today. Thank you for bringing it to my attention! /Jacob On Thu, Mar 10, 2011 at 5:57 AM, Neal Walters wrote: > I'm using the the Data tab of the Web-Admin (V1.3.M03) to model my data > structure and learn Neo4j. > I accidentally created a wrong relationship.
