README
Sample Ruby application to read [OpenBeacon](http://www.openbeacon.org) RFID tracking sightings into a neo4j graph.
and visualizing a RFID-Graph with Neovigator (connected donuts)
## Data Model
(person {name, twitter,github})-[:HAS_TAG]->(tag {tag})
### Simple with talk as relationship
tag1-[talk:TALKED {begin,end}]->tag2 # simple model
### Advanced with talk as node
tag1-[:TALKED]->(talk {interval,begin,end})<-[:TALKED]-tag2
// old data (later than TIMEOUT) pushed to separate node
talk-[:PREV]->(prev {interval,begin,end})
## Usage
### Setup Openbeacon Tracker
1. get openbeacon tags and reader, configure the reader via serial port to an ip network of your choice
2. power the reader via USB or PoE and connect to your machine, make sure to set it up as the _server-ip_ from the reader configuration
3. put batteries in the tags and use them
4. clone the [openbeacon github repository](https://github.com/meriac/openbeacon)
5. go to `openbeacon/host/services/openbeacon-tracker`
5. enter your reader as `{0x457 /*=id 1111*/ , 1 /* room */, 1 /* floor */, 1 /* group */, 100 /* X */, 100 /* Y */},` in `bmReaderPositions.h`; run `make`
6. run ./openbeacon-tracker 2>&1 | ./filter-singularsighting logs/sightings.json
7. those json files can then be polled and inserted into the neo4j graph
### Configure and Start the Neo4j Server
1. [download](http://neo4j.org/download) and unzip Neo4j server
* add `node_auto_indexing=true` and `node_keys_indexable=tag,name,twitter,github,interval` to `/path/to/neo4j/conf/neo4j.properties`
* start the server with `/path/to/neo4j/bin/neo4j start`
### Configure the data insertion
apt-get install ruby rubygems
sudo gem install bundler
bundle install
Make a people.cvs file (name,rfid-tag-id,twitteraccount):
head people.cvs
>David Peart,554,
>Marcus Ericsson,573,mericsson
Import the people
bundle exec -Ilib lib/people.rb people.csv
pull in tag data from openbeacong tracker every 20s
while [ true ]; do bundle exec -Ilib lib/parse.rb path/to/last_json; sleep 20; done
* enjoy and go hacking [Visualizations from OpenBeacon at BruCON 211](http://www.openbeacon.org/BruCON_2011)
### Neovigator
* `bundle install`
* `bundle exec rackup #Â neovigator webapp`
* push it to heroku and add the neo4j add-on (`heroku addons:add neo4j --neo4j-version 1.8.M06`)
