Re: [Neo4j] Hello list
Hola Jose y Max! Que lindo que podemos hablar un poquito en español! :) Jose, queres saber que algoritmos usamos para guardar la information en el disco duro, o que algoritmos usamos en GraphAlgo? --- Hi Jose and Max, How nice to be able to talk a bit in spanish! :) Jose, do you want to know what algorithms we use to persist data, or what algorithms we use in GraphAlgo?

Parece que estas preguntado cual es el modelo que neo4j usa, pero no entendemos a lo que te refieres. El modelo es cualquier cosa que puedes modelar con simple puntos y relaciones. Los puntos pueden ser de cualqier forma (con tal de que sean un Java Primitive, tambienes puedes usar a String para reprecentar algo mas complicado con JSON o algo parecido). No puedes tener un punto que sea otra grapha, pero si necesitas hacer algo asi lo puedes hacer con segmentos de puntos desconectados y temporariamente crear relaciones entre los puntos cuando necesitas. - What is your question is spanish? I can translate for you. It seems like you are asking what model neo4j uses, put we do not understand quite what you are referring to. The model is whatever you can describe with a series of nodes and relationships. The nodes can be anything (as long as they are Java Primitives, you can also use a String to represent something more complicated using JSON or whatever). You cannot have a node that is itself a graph, but if you need to do something like this, you can do it with disjointed node segments and temporarily create relationships between them as you need them. --Max On Tue, Nov 16, 2010 at 7:23 PM, Jose Angel Inda Herrera jai...@estudiantes.uci.cu wrote: Andrea Taylor sorry by my english, realy is bad.

Re: [Neo4j] Neo4j REST Server with path prefix
Hi Christopher, We've deprecated the REST API from this release in favour of an overall Server platform (which combines the REST API, Web Admin interface, and other bits of platform), so we'll treat this as a feature request for the server. In the meantime, I've lodged a ticket: https://trac.neo4j.org/ticket/280 Jim On 8 Nov 2010, at 16:08, Christopher Schmidt wrote: Hi all, how can I setup the REST server to use a standard url path prefix?

Re: [Neo4j] Neo4j REST Server with path prefix
Christopher, also, of course the mounting of custom REST resources is going to be supported, so you for instance can write a JavaScriptInterpreter (good thought, we think it would be great to have one as default!) and mount it. But not in the first version, will need some more days for that :) 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://www.thoughtmade.com - Scandinavia's coolest Bring-a-Thing party.

[Neo4j] sobre neo
Hola Andres , Si me interesa saber como es que neo almacena los datos, seria eso de mucha ayuda para mi. Sobre el modelo de datos, me dices que es la teoria de grafos, pero existe algun documento que tenga neo que trate sobre como utiliza el la teoria de grafo en su modelo de datos, Gracias de ante mano PD: es genial poder hablar en espanol. ___ Neo4j mailing list User@lists.neo4j.org https://lists.neo4j.org/mailman/listinfo/user

[Neo4j] REST support for neo4j-spatial

OK. I think I'm beginning to get an idea of what you want. You have a CMS, and some of the data is geolocated, in the sense that you know what countries it is associated with, and perhaps you even have relationships to 'country' nodes (or other nodes) representing locations. Now you want to use Neo4j Spatial to perform simple spatial queries on this. Your analysis is correct and brilliant. :-) In my case, the CMS payload data itself (like HTML, Images, Videos, CSS, JS, Blogs etc.) is stored in neo4j nodes. But logging data, too, of course. I could imagine something like: 'give me all countries in the specified region (bounding box) and include the number of pages as an attribute of the result set'bute? Right now I'm using the SearchIntersectWindow class to determine which countries are needed to display within a certain global region. The countries data is loaded as a set of GeoJSON files via Javascript (using Polymaps), so neo4j spatial does only provide the country names. I think you should either use the original shapefiles and the existing ShapefileImporter or move to OSM data models for connected topologies. A GeoJSON importer is a nice idea, but not worth the effort if you already have shapefiles. Indeed! I ended up with using the shapefile importer, using neo4j spatial to serve geodata nodes which are then connected on-the-fly with geo-tagged CMS data. Your comments and suggestions helped me a lot, so I just wanted to say thanks again. Axel ___ Neo4j mailing list User@lists.neo4j.org https://lists.neo4j.org/mailman/listinfo/user
