Re: [Neo4j] Arnoldi iteration

Lorenzo, sorry for taking so long time - missed your CLA mail. Anyway, we got it, thanks! Now, could you raise and issue in trac.neo4j.org and attach your patch against the current graph-algo trunk so we can include it into the code? Would be great to have this coming in. Cheers, /peter

Re: [Neo4j] BatchInserter for RTree

Craig, Davide, any progress on this? Also, it seems like the current focus is on a good layout for the OpenStreetMap importer. Is there anyone on this list familiar with the internal representation of OSM? From the XML files, it looks like we could construct a very cool and dense graph that

Re: [Neo4j] BatchInserter for RTree

I think I could add a layer for all points, but I do not see the value. In fact the current layer with all line-segments (all ways) is only an interim layer so that something can be shown. I think I really want the meaningful layers (streets, rivers, counties, etc.) and once those work I'm tempted

[Neo4j] EmbeddedReadOnlyGraphDatabase vs. EmbeddedGraphDatabase

Hi, What's the difference (advantages) between EmbeddedReadOnlyGraphDatabase and EmbeddedGraphDatabase?! I have the following simple code: MapString, String configuration = EmbeddedReadOnlyGraphDatabase.loadConfigurations(CONFIG_DB_PATH); GraphDatabaseService neoInstance

Re: [Neo4j] Optimizing neo4j for traversal in Spring

Hi Paddy, You could let Spring coerce a Properties object into a MapString, String for the config. Basically just wire your graphDbService with an additional constructor arg that is the Properties object with your properties. You can construct this object using spring-util (PropertiesFactoryBean)

[Neo4j] neo4j-spatial and jython

hi, I am working on importing geospatial data (SHP/OSM) into the neo4j. I have neo4j-spatial and also jython but I am not sure how to use this python binding for the neo4j-spatial. can anyone please give me some clues to get it started. thanks, sima ___

Re: [Neo4j] BatchInserter for RTree

Many features are just points, so we need to add them to the spatial index. Maybe is not useful to add all nodes as points, but I think we should add at least every nodes which isn't in a Way. Actually, my plan is to create an index for each identifiable layer. This means geometries are

Re: [Neo4j] BatchInserter for RTree

Craig, sounds great. Actually, I think we are close to understanding the OSM thinking in building up their data, and it seems to be a very good fit with Neo4j graph thinking. Given the interesting and good explanations at http://wiki.openstreetmap.org/wiki/Map_Feature and

Re: [Neo4j] neo4j-spatial and jython

You would use it like you use any other Java library from Jython. The Python bindings for Neo4j[1] do not extend to neo4j-spatial (yet). Cheers, Tobias [1] http://components.neo4j.org/neo4j.py/ On Thu, Jul 15, 2010 at 8:59 PM, sima lotfi sima.lo...@gmail.com wrote: hi, I am working on

[Neo4j] Question about ID indices...

Hello, Question: Is the node/relationship ID space indexed by Lucene --- and, if so, in a manner analogous to properties? Thank you, Marko. http://markorodriguez.com ___ Neo4j mailing list User@lists.neo4j.org

Re: [Neo4j] neo4j REST server standalone

I downloaded the July 10th build of the REST standalone server and created a neo4j.properties file with enable_remote_shell set to true. However, when I try to connect it, I still get the locked store message and it prompts me to open as readonly. Do I also need something in the

Re: [Neo4j] Question about ID indices...

In the current IndexService API you can't really query for IDs. But in a new index framework that I've been working on you can... you can also do composite queries (allowing you to ask lucene queries directly) and all such goodies. Lucene is just an implementation whereas the API is generic. Take

[Neo4j] BatchInserter performance

Hi, I have instantiated a neo4j store (on a machine with 32GB RAM) with a root node, a sub-ref node and 400 million nodes connected to the subref node with the same relationship type. Each one of these nodes has 3 properties (int, long, String) all of which were indexed using something

[Neo4j] Lucene and sorting results

Hi all, I've been evaluating using Neo4J for a project at my company and have been consistently impressed with it's capabilities. There is one thing I need to do, however, that I'm not sure is possible. I'm using the Neo4J REST server. I've been using lucene full text indexing/searching on my
