= Thingfish PostgreSQL Metastore

* http://bitbucket.org/mahlon/thingfish-metastore-pggraph

== Description

This is a metadata storage plugin for the Thingfish digital asset
manager.  It provides persistent storage for uploaded data to a
PostgreSQL table.

It is heavily based on the regular PG metastore, however it differs by
storing objects as nodes, and their relations as edges.

== Installation

    $ gem install thingfish-metastore-pggraph


==  Usage

As with Thingfish itself, this plugin uses
Configurability[https://rubygems.org/gems/configurability] to modify
default behaviors.

Here's an example configuration file that enables this plugin.

	---
	thingfish:
	  metastore: pggraph

	pggraph_metastore:
	  uri: postgres://thingfish:password@db.example.com/database


When Thingfish starts, it will install the necessary database schema
automatically.
