+SUMMARY="Open standard for machine learning interoperability"
+DESCRIPTION="Open Neural Network Exchange (ONNX) is an open ecosystem that empowers AI developers \
+to choose the right tools as their project evolves. ONNX provides an open source format for AI \
+models, both deep learning and traditional ML. It defines an extensible computation graph model, \
+as well as definitions of built-in operators and standard data types. Currently we focus on the \
+capabilities needed for inferencing (scoring)."
