[Neo4j] Set reference node through REST API
Hi all, As far I know, the REST API always returns a reference node. But in case of I delete it, there's no option to set it again through REST API. I read in this list that you could do this in Java like next: graph.delete(); newRoot = neo4j.createNode(); neo4j.setReferenceNode(newRoot); But I don't know the way to do this using the REST API. Even if I don't delete it anything, I would have to be able to set the reference node to a node of my preference. I know that was discussed previously, but is the reference node really needed?

Re: [Neo4j] Set reference node through REST API
No, it isn't needed. It is very helpful as an "attachment point" for other nodes and point of entry for traversals, but it isn't required. -Original Message- From: user-boun...@lists.neo4j.org [mailto:user-boun...@lists.neo4j.org] On Behalf Of Javier de la Rosa Sent: Saturday, August 27, 2011 12:14 PM To: Neo user discussions Subject: [Neo4j] Set reference node through REST API Hi all, As far I know, the REST API always returns a reference node.

[Neo4j] Loading WordNet 3.0 RDF into Neo4j?
Has anyone here loaded WordNet 3.0 (http://wordnet.princeton.edu/) into Neo4j or have pointers for doing so? WordNet 2.0 is in RDF form (http://www.w3.org/2006/03/wn/wn20/) as well as 3.0 (http://semanticweb.cs.vu.nl/lod/wn30/). What's the best way to load/convert RDF data into Neo4j?

[Neo4j] neo4j 1.4.1 Examples
I have just downloaded neo4j 1.4.1 and started with the server examples. The example code seems to not have been updated for 1.4.1 as the interfaces have changed. This is confusing for self-learning. Would the forum recommend returning to the earlier version for self-learning or is there a new version of the examples? Just curious. Thanks. -- View this message in context: http://neo4j-community-discussions.438527.n3.nabble.com/neo4j-1-4-1-Examples-tp3289429p3289429.html Sent from the Neo4j Community Discussions mailing list archive at Nabble.com. ___ Neo4j mailing list User@lists.neo4j.org https://lists.neo4j.org/mailman/listinfo/user

I would try the blueprints rdf importer. look at my github home (peterneubauer) for a project to import rdf from dbpedia which should work for any rdf.

[Neo4j] Delete all contents in graph?
Is there a function to delete all contents in the graph? Raffi ___ Neo4j mailing list User@lists.neo4j.org https://lists.neo4j.org/mailman/listinfo/user
Re: [Neo4j] Delete all contents in graph?
Raffi, you can do something like https://github.com/neo4j/community/blob/master/kernel/src/test/java/org/neo4j/test/ImpermanentGraphDatabase.java#L203, basically walking all nodes and deleting the relationships, and delete the nodes after that. Would that work? Otherwise, simple shutdown the DB, delete the database dir and start it again.

Re: [Neo4j] BatchInserterIndex and ValueContext[]
Hi Peter, > Could you provide a test and maybe fix it (fork on > GIThub)? Would be awesome! No problem, I'll send you a pull request tonight. I still have one question that already had come to my mind while testing my own app: Have you ever thought of implementing a GraphDatabaseService backed by a main memory store? This could be really usefull for unit testing, so you don't have to do things like cleaning up your environment after each test. Just shut down the graph database service and everyting is in a well defined, clean state again.

Re: [Neo4j] BatchInserterIndex and ValueContext[]
Ben, great, will merge it in as soon as you send in the CLA, see http://wiki.neo4j.org/content/About_Contributor_License_Agreement For testing, we normally use the ImpermanentGraphDatabase which does exactly this. It's not in RAM, but does the cleanup :) /peter On Sun, Aug 28, 2011 at 12:51 AM, Benjamin Gehrels < neo4j-mailingl...@gehrels.info> wrote: > Hi Peter, > > > Could you provide a test and maybe fix it (fork on > > GIThub)?

It's not in RAM, but does the cleanup :) That one looks cool, maybe it's possible to move it from src/test/java to src/main/java so it will be included into the distribution jars and can be used outside the neo4j build infrastructure? ___ Neo4j mailing list User@lists.neo4j.org https://lists.neo4j.org/mailman/listinfo/user
