Config

You must configure a mapping type → structure

neo4j:
  host: localhost
  port: 7474
types:
  thing: node
  relation: arc
  equiv: equivalence

(in config.yaml, config.json or --config [filename.json|filename.yaml])

Input

Input data elements are of this form

{
  dataset: /* string */,
  type: /* what you defined in config */,
  operation: /* 'add' or 'remove' */

  // all optional, depends on the structure
  id: '123',
  s: '123',
  t: '123',

  // whatever you want
  data: { /*...*/ }
}

API

One function, input: stream, output: stream.

Example code

var H = require('highland');
var Graphmalizer = require('graphmalizer-core');

var config = {
    Neo4J: { host: 'localhost', port: 7474 },
    types: {
        thing: { node:{} },
        eats: { arc:{} },
        same: { equivalence: {} }
    }
}

var G = new Graphmalizer(config)

var stream = H([ {type: 'thing', id: 'x'} ]);

G.register(stream)
  .each(H.log);

Neo4J

Installation on OSX

Homebrew does the trick.

brew install --devel neo4j
neo4j start

Authorization

Either set config.Neo4J.auth to user:pass

var G = new Graphmalizer({
    Neo4J: { auth: 'neo4j:neo4j' },
    types: { /* ... */ }
})

Or disable HTTP authentication all together, see neo4j manual for details.

Set the following in the conf/neo4j-server.properties file and restart server, neo4j restart.

# Disable authorization
dbms.security.auth_enabled=false

If you don't know where this file is, you can try mdfind neo4j-server.properties on OSX.

Development

You can also use the wercker commandline interface.

Setup docker host (automatically starts it) or just start it if you have done this before (check with docker-machine ls).

docker-machine create -d virtualbox graphmalizer
docker-machine start graphmalizer

Then you want to update your shell so I knows about the docker host.

eval $(docker-machine env graphmalizer) # bash
eval (docker-machine env graphmalizer)  # fish

Now you can build and test using wercker:

wercker build
