## Description

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

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.
