Pulling out data is somewhat generic. That data will come from where ? A SQl connection, an excel file, one of the configured data sources in the platform (Analysis, Metadata) ? Your plugin will always pull data from the same place or should the user specify the origin ?

Depending on what you're trying to achieve, there's a multitude of options - use the data access layer, connect directly to models and issue mdx queries (like Saiku or pivot4j does), use CDA (Community Data Access) so that the user needs to provide a CDA file and your plugin is able to query that, get the data and apply your data mining magic to it (btw, do you know Weka? - might save you some work).
