I'm still a little confused on this and am hoping for more clarification, I'm still on the very steep learning curve side of "newbie", please bear with me...
I can start up a neo4j rest server and successfully add nodes and edges. I can see that I have neo4j spatial installed. I can also start up geoserver, and it connects without complaint to my neo4j database via the "file:" interface. Unfortunately it doesn't see anything in it. I have my raw data in various formats, including a geojson file. I tried just adding the geojson structure as a node, but that didn't work... I'm still really unclear as to how to get my data into a layer in neo4j (preferably using the REST interface) that will be recognized by geoserver. I'm guessing that first you can create an empty "layer". In your example below, is that what you are doing? What do you mean by "returns the original node"? I suppose a single neo4j instance can have multiple independent layers in it. Is that true? Your example layer appears to be titled "buildings". Does that mean it will contain the shapes of buildings, or the point locations of buildings (or both)? How do you add a 'building' (of either type) to the layer? I'm assuming your example does not add any buildings because there is no discernible location information in the data below. My locations are all defined by latitude/longitude pairs. At the moment I'd like to start by adding simple "points" in a layer. Eventually I'd like to add edges and shapes, but I'd be really happy just to be able to get points mapped first. aTdHvAaNnKcSe ! > Axel, > I just pushed a first version of a Neo4j Spatial server plugin to github, > see > > https://github.com/neo4j/neo4j-spatial/blob/f9e75ac62867ecd3fc178f01cfc8bbb40abda3ff/src/main/java/org/neo4j/gis/spatial/server/plugin/SpatialPlugin.java > > Basically, you copy all dependencies and the neo4j-spatial JARs (get > them with "mvn dependency:copy-dependencies" into target/dependency) > into $NEO$J_SERVER/plugins and you should get something like > > [~] $curl -H "Accept: application/json" http://localhost:7474/db/data/ > { > "extensions-info" : "http://localhost:7474/db/data/ext";, > "node" : "http://localhost:7474/db/data/node";, > "node-index" : "http://localhost:7474/db/data/index/node";, > "relationship-index" : > "http://localhost:7474/db/data/index/relationship";, > "reference_node" : "http://localhost:7474/db/data/node/0";, > "extensions" : { > "GetAll" : { > "get_all_nodes" : > "http://localhost:7474/db/data/ext/GetAll/graphdb/get_all_nodes";, > "getAllRelationships" : > "http://localhost:7474/db/data/ext/GetAll/graphdb/getAllRelationships"; > }, > "SpatialPlugin" : { > "addPointToLayer" : > "http://localhost:7474/db/data/ext/SpatialPlugin/graphdb/addPointToLayer"; > } > } > } > > And then you add stuff with > > > [~] $curl -H "Accept: application/json" -d > "node=http://localhost:7474/db/data/node/0&layer=buildings"; > http://localhost:7474/db/data/ext/SpatialPlugin/graphdb/addPointToLayer > [ { > "outgoing_relationships" : > "http://localhost:7474/db/data/node/0/relationships/out";, > "data" : { > "name" : "Fredrik" > }, > "traverse" : > "http://localhost:7474/db/data/node/0/traverse/{returnType}";, > "all_typed_relationships" : > "http://localhost:7474/db/data/node/0/relationships/all/{-list|&|types}", > "property" : "http://localhost:7474/db/data/node/0/properties/{key}";, > "self" : "http://localhost:7474/db/data/node/0";, > "properties" : "http://localhost:7474/db/data/node/0/properties";, > "outgoing_typed_relationships" : > "http://localhost:7474/db/data/node/0/relationships/out/{-list|&|types}", > "incoming_relationships" : > "http://localhost:7474/db/data/node/0/relationships/in";, > "extensions" : { > "ShortestPath" : { > "shortestPath" : > "http://localhost:7474/db/data/ext/ShortestPath/node/0/shortestPath"; > }, > "DepthTwo" : { > "nodesOnDepthTwo" : > "http://localhost:7474/db/data/ext/DepthTwo/node/0/nodesOnDepthTwo";, > "relationshipsOnDepthTwo" : > "http://localhost:7474/db/data/ext/DepthTwo/node/0/relationshipsOnDepthTwo";, > "pathsOnDepthTwo" : > "http://localhost:7474/db/data/ext/DepthTwo/node/0/pathsOnDepthTwo"; > } > }, > "create_relationship" : > "http://localhost:7474/db/data/node/0/relationships";, > "all_relationships" : > "http://localhost:7474/db/data/node/0/relationships/all";, > "incoming_typed_relationships" : > "http://localhost:7474/db/data/node/0/relationships/in/{-list|&|types}" > } ] > > Of course, this just creates the layer and returns the original node, > but still, looking at the db give us > > [~] $neo4j-shell > :/Users/peterneubauer/program/neo4j-server/lib/geronimo-jta_1.1_spec-1.1.1.jar:/Users/peterneubauer/program/neo4j-server/lib/neo4j-1.2.M06.jar:/Users/peterneubauer/program/neo4j-server/lib/neo4j-examples-1.2.M06.jar:/Users/peterneubauer/program/neo4j-server/lib/neo4j-graph-algo-0.7-1.2.M06.jar:/Users/peterneubauer/program/neo4j-server/lib/neo4j-ha-0.5-1.2.M06.jar:/Users/peterneubauer/program/neo4j-server/lib/neo4j-index-1.2-1.2.M06.jar:/Users/peterneubauer/program/neo4j-server/lib/neo4j-kernel-1.2-1.2.M06.jar:/Users/peterneubauer/program/neo4j-server/lib/neo4j-lucene-index-0.2-1.2.M06.jar:/Users/peterneubauer/program/neo4j-server/lib/neo4j-management-1.2-1.2.M06.jar:/Users/peterneubauer/program/neo4j-server/lib/neo4j-online-backup-0.7-1.2.M06.jar:/Users/peterneubauer/program/neo4j-server/lib/neo4j-remote-graphdb-0.8-1.2.M06.jar:/Users/peterneubauer/program/neo4j-server/lib/neo4j-shell-1.2-1.2.M06.jar:/Users/peterneubauer/program/neo4j-server/lib/neo4j-udc-0.1-1.2.M06-neo4j! .jar:/Users/peterneubauer/program/neo4j-server/lib/netty-3.2.1.Final.jar:/Users/peterneubauer/program/neo4j-server/lib/org.apache.servicemix.bundles.jline-0.9.94_1.jar:/Users/peterneubauer/program/neo4j-server/lib/org.apache.servicemix.bundles.lucene-3.0.1_2.jar:/Users/peterneubauer/program/neo4j-server/lib/protobuf-java-2.3.0.jar > NOTE: Remote Neo4j graph database service 'shell' at port 1337 > Welcome to the Neo4j Shell!
