PMML - Predictive Model Markup Language
A standard developed by the Data Mining Group (DMG) to represent predictive analytic models. Predictive Model Markup Language (PMML) is supported by leading business intelligence and analytics vendors like IBM, SAS, MicroStrategy, Oracle and SAP.
The XML-based PMML enables sharing predictive analytic models between different applications, making it possible, for example, to build a model in one system and then move it to another system to test its performance against a test data set.
The latest version of PMML, 4.0, was released on June 16, 2009.
