[wdmmg-discuss] RFC: Web OLAP API

[Stefan Urbanek]

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):

	http://bit.ly/bTnBoP

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

What do you think?
