Beset is a simple DB for storing and querying set datastructures.


To build Beset with rebar:

   rebar clean update-deps compile eunit  generate

To start:

   ./rel/beset/bin/beset start


Beset will run on port 9999 by default:  http://127.0.0.1:9999

To add a set, POST  a JSON list:

   curl -v -H "Content-Type: application/json" -X POST -d '["1","2","3","4"]' http://127.0.0.1:9999

To query for subsets, make a GET request to '/subsets/' with a URL encoded JSON list as the 'superset' query parameter:

   curl -v http://127.0.0.1:9999/subsets?superset=%5B1%222%223%224%225%226%227%228%229%5D

The response will be a JSON list of the form [{SetId: Set},{SetId: Set}...]

Example:

> GET /subsets?superset=%5B1%222%223%224%225%226%227%228%229%5D HTTP/1.1
