This is an example project and testbed for mondrian-rest, a REST endpoint for the OLAP server Mondrian.

It implements a simple OLAP Cube with data from the UN COMTRADE database, as republished by the Observatory of Economic Complexity

Requirements

Installation

  • Download the DB dumpACHTUNG: it's a ~1.3 GB file.
  • Create a DB in your Monet server: monetdb create oec; monetdb release oec
  • Import the dump into your DB: xzcat oec_dump.sql.xz | mclient -u monetdb -d oec (this will take a while)
  • If needed, adjust the connection parameters in config.ru
  • Run: rackup
