[wdmmg-discuss] RFC: Web OLAP API

Thu Aug 26 15:26:21 UTC 2010

Hi,

I've discussed with Rufus Pollock one or two weeks ago, that it would be nice to have common API for data analysis. For our projects we are using Brewery[1] - open-source ruby framework I am developing. The framework provides simple functionality for OLAP and multidimensional data cubes, inspired by Oracle tools.  By simple I mean: only multidimensional abstraction of relational data through logical data model, no precomputed cubes, no multidimensional data storage, no materialized views. Not yet :-) The logical model is based on snowflake schema [2].

I've created a draft document of proposed Web OLAP API, that we are planning (and partially using for some URLs):

The API reflects functionality available in Brewery (example of use in [3] for model [4], not localized).

What do you think?
