Re: [Neo4j] Neo4j spatial
Saikat, which approach to use - atomic REST calls or a server plugin to work in the background - depends on the load of things. If you are importing stuff in the beginning, I would not use REST. If you are thinking about normal operations with moderate load, I think REST will be fine.

One of the best places is the set of test cases included in neo4j spatial. You can find them at https://github.com/neo4j/neo4j-spatial/tree/master/src/test/java/org/neo4j/gis/spatial. In particular, since you are interested mostly in point data, take a look at TestSimplePointLayer.javahttps://github.com/neo4j/neo4j-spatial/blob/master/src/test/java/org/neo4j/gis/spatial/TestSimplePointLayer.javaand LayersTest.javahttps://github.com/neo4j/neo4j-spatial/blob/master/src/test/java/org/neo4j/gis/spatial/LayersTest.java . What you will find in those classes is Java code for adding points to the database, similar, but more extensive than the code in the blog. Regarding your specific case, if you are working with a normal google map or bing map, and want to port the points into a local database, you would need to export them, and write a simple importer. If you have written a mashup between google or bing maps and your own neo4j-based web application, you should be able to use some client side coding to automate this, accessing the map, and posting the points directly into your own server (where of course you would have some code adding the points to the database). Does this answer your question?

Re: [Neo4j] Representing Statements About Statements
Chris,
the current approach to that is through the Tinkerpop Sail
implementation on top of Neo4j, see
https://github.com/tinkerpop/blueprints/wiki/Sail-Ouplementation.
Basically, you do
Sail sail = new GraphSail(new Neo4jGraph('rdf-store'));
SailConnection sc = sail.getConnection();
ValueFactory vf = sail.getValueFactory();
sc.addStatement(vf.createURI(http://tinkerpop.com#1;),
vf.createURI(http://tinkerpop.com#knows;),
vf.createURI(http://tinkerpop.com#3;),
vf.createURI(http://tinkerpop.com;));
sc.addStatement(vf.createURI(http://tinkerpop.com#1;),
vf.createURI(http://tinkerpop.com#name;), vf.createLiteral(marko),
vf.createURI(http://tinkerpop.com;));
sc.addStatement(vf.createURI(http://tinkerpop.com#3;),
vf.createURI(http://tinkerpop.com#name;), vf.createLiteral(josh),
vf.createURI(http://tinkerpop.com;));
System.out.println(get statements: ?s ?p ?o ?g);
CloseableIteration? extends Statement, SailException results =
sc.getStatements(null, null, null, false);
while(results.hasNext()) {
System.out.println(results.next());
}
System.out.println(\nget statements: http://tinkerpop.com#3 ?p ?o ?g);
results = sc.getStatements(vf.createURI(http://tinkerpop.com#3;),
null, null, false);
while(results.hasNext()) {
System.out.println(results.next());
}
HTH? Let me know if you need help setting this up!

Hi,
I'm new to Neo4j, and I'm trying to evaluate it as an RDF quadstore.
Specifically, where a quad is a 4-tuple of the format (id, subject,
predicate, object), quadstores can represent statements about
statements by using the id from one quad as the subject, predicate, or
object in another quad. Some stores also support a feature called
named graphs, where entire sets of quads are grouped, allowing the
group to have statements bound to it in a similar way.
Has anyone used Neo4j to do anything like this? If so, how is it
accomplished, and what is the Neo4j-equivalent terminology?

Chris

Re: [Neo4j] Problems installing neo4j.py on Mac
It is a known issue. A parsing problem in one of the transitive pom.xml files. I don't quite understand why, because from what I remember from investigating it, that key was present. It is probably an xml-namespace problem. The key is declared (in the xml file) without namespace qualifiers, and elementree needs explicit namespace qualifiers EVERYWHERE. I am working on a new version of the installation script to circumvent the problem. ETA is soon, but not specific yet (I keep getting interrupted by other tasks), but at least this is a prioritized task now, which means it WILL get done.

Using the other method you can do the same thing: index.query( name:matt* ); index.query( name:matt* OR name:persson ); _but_ you can also query stuff from different property keys in one query, making compound queries possible, like: index.query( name:matt* AND profession:hacker ); Can anyone shed any light on how all this stuff works in the context of fulltext? Definitely some more examples/documentation would be very helpful. The query methods are also available for exact indexes. The difference between fulltext and exact is the way the added values are tokenized. The exact index doesn't do any tokenization, just puts the values as one value, whereas fulltext index tokenizes the added values into individual words and indexes those separately.

And know that the exact limitation you ran into spawned the creation of this new API. I started using this framework from day 1 since I'm new and I don't have background from Node.traverse(). If I understand correctly this will be THE traversal framework right? It's experimental but you use this from within Node.traverse so it's not that experimental I guess? ... Did you suggest to use this or the old API? I think that the functionality of it is not going to change... or at least features won't be removed, only added/changed. The API can come to change quite a bit, maybe with tighter integration with the other core interfaces (Node, Path a.s.o.). So by using it you're using a stable/battle-tested traversal framework functionality-wise, but may be forced to migrate your traversal code at a later point, even though it might still be left @Deprecated so that you can decide yourself when to migrate. Nothing of what I said is decided upon so I'm speculating a bit here. In terms of stability of the API the old might be safer, but there are things that you just cannot do with it. So if you hit such a road block with the old API then go with new. I personally use only the new. Plus the page you mention isn't well linked in the wiki... I think you're right about that.

Then, we can look at the server setup and see what is needed to be better in the docs :) Cheers, /peter neubauer GTalk: neubauer.peter Skype peter.neubauer Phone +46 704 106975 LinkedIn http://www.linkedin.com/in/neubauer Twitter http://twitter.com/peterneubauer http://www.neo4j.org - Your high performance graph database. http://startupbootcamp.org/ - Öresund - Innovation happens HERE. http://www.thoughtmade.com - Scandinavia's coolest Bring-a-Thing party.

To: Neo4j user discussions user@lists.neo4j.org 2011/3/16 Rick Bullotta rick.bullo...@burningskysoftware.com Hi, all. Looking at the documentation for the new index framework in the Wiki at: http://wiki.neo4j.org/content/Index_Framework, it isn't all that clear how fulltext queries are to be executed (what's the key name?), how they can be sorted (can you sort by score?), etc. Anders is working on that documentation and will arrive any day now. But until then I could outline some information here: So, there are two #query methods, one with and one w/o key. The one with the key parses the query you enter, assuming that everything is about that property key, f.ex if you've added: index.add( node, name, Mattias Persson ); to a fulltext index and then query (remember that fulltext index lower-cases everything by default): index.query( name, matt* ); // or index.query( name, matt* OR persson ); it will query for matt* (or matt* OR persson) values for the name property. Using the other method you can do the same thing: index.query( name:matt* ); index.query( name:matt* OR name:persson ); _but_ you can also query stuff from different property keys in one query, making compound queries possible, like: index.query( name:matt* AND profession:hacker ); Can anyone shed any light on how all this stuff works in the context of fulltext? Definitely some more examples/documentation would be very helpful. The query methods are also available for exact indexes. The difference between fulltext and exact is the way the added values are tokenized. The exact index doesn't do any tokenization, just puts the values as one value, whereas fulltext index tokenizes the added values into individual words and indexes those separately.

Re: [Neo4j] Where is the beer?
When I added my face, I tested to make sure it scaled the same as the others. The results: no images scale at all, no matter what zoom level. They are all fixed size images.

I went with a face at first, but since it didn't scale, it just looked ridiculous. Maybe scaled down to 32x32 or something like that would work.

Re: [Neo4j] Representing Statements About Statements
Thanks with the clarification. Is the Sail RDF interface at all accessible from Python, such as via neo4j.py?

How would I add a statement, explaining the attribution of each of these statements and the time when they were added? For example, if the first statement was entered-by a specific person on a specific date, I would represent this in RDF like: Peter's example was just showing you the basics of getting an RDF store going over Neo4j. He did not get into the complications of reification (statements about statements). You will need to use Sail quad store functionality. This is where you have named graphs and you can make statements about named graphs. Such issues are for an RDF mailing list. However, here is some specifics in very brief notations so I don't have to type so much: a knows b g1 b likes c g2 These are two quads -- spog. You can now make reference to the forth component called the 'named graph' or 'context.' a believes g2 g1 Thus, a is asserting that he believes that b likes c. This is all possible through Blueprints Sail which is the binding you can use to easily make Neo4j an RDF quad store. Blueprints Sail just binds the Sail API to Neo4j.
