I have always maintained that the simple lang-like extension stuff fits in Jakarta Commons, while the math/stat framework stuff does not.
I partially disagree with the framework comment. Mainly, because a precedent has been set with commons-logging for allowing such a framework as envisioned by the [math] members. Quoting the [logging] home page: "The Logging package is an ultra-thin bridge between different logging libraries. Commons components may use the Logging API to remove compile-time and run-time dependencies on any particular logging package, and contributors may write Log implementations for the library of their choice." I foresee the proposed [math] API as providing the same purpose; providing a mathematical API where contributors may write "implementations for the library of their choice."
Good point. I guess it really keeps coming back to a discussion of scope (as you point out below).
I think that it is to accommodate the framework and non-Java development ideas that Robert is recommending the move to Apache Commons. I agree with him.
Any non-Java work definitely does not belong in Jakarta, Commons or elsewhere.
I would recommend, however, that the proposal be rewritten to reflect the broader scope.
No problem with that. I will concede, that the [math] group is, IMO, trying to take on too many endeavors at once and maybe a reality check is in order.
In the near-term for [math], this is what I would like to see: 1) a 1.0 release 2) expand on the 1.0 features for the next release (i.e. add more distributions, hypothesis tests, root finders, etc.). 3) add ONE new math vertical/discipline for the next release. For instance, we could chose to add a FFT implementation which some people have expressed a desire to have. 4) make another release.
For the long-term, I would just keep repeating that cycle. I think this would keep the [math] contributors primarily focused on the things you care about, the mathUtils portion, and with some attention allotted to broadening [math] into the package of our dreams (or nightmares depending on your point of view).
Sounds reasonable to me.
