Thank you for your comment.

You are correct that most of the code currently available in these repos are examples.

However, it is quite easy to construct a library of SAS macros (called a catalog). We or others could create such a library and commit it to these repos.

In SAS, the primary data mining and machine learning library is currently supplied by Enterprise Miner. (It is a collection of procedures, macros, and a graphical user interface.) I personally have not yet found it necessary to create an additional library of data mining and machine learning functionality to augment Enterprise Miner.

I acknowledge that purchasing a proprietary library is quite different than a group of users working together to create an open source library.
