Predictive Model Markup Language. A new industry standard created by IBM and Oracle that allows models to move from system to system.

Predictive Model Markup Language. PMML is an XML language developed by the Data Mining Group used for describing statistical models. PMML Models can be used by any PMML-compliant product. Translators exist which translate some proprietary formats into PMML. Currently, PMML is also used to describe transformations and aggregations of attributes to create derived attributes. There are proposals to create a separate markup language called DXML to described these types of transformations.
