A few years ago, Wolfram Inc. not only started to rename things around Mathematica, a lot of new technologies and frameworks were introduced as well. Now, we are left with a lot of acronyms and similar sounding frameworks/technologies and it is hard to keep track what they do and how they are related to Mathematica.
One prominent example is the acronym WSTP which is the new acronym for the famous MathLink protocol that was renamed. If that itself was not enough, we nowadays have to deal with WDF, W|A, WPL, WPC or with products like Wolfram Data Science Platform that have descriptions which raise more questions than they answer:
[..] a revolutionary system for data science. Take numerical, textual, image, GIS or other data and give it the Wolfram treatment, carrying out a full spectrum of data science analysis and visualization and automatically generating rich interactive reports — all powered by the revolutionary knowledge-based Wolfram Language.
Well, this is exactly what I do with my local Mathematica, or should I rather say my Wolfram Desktop Option for Wolfram Cloud Products? Who knows? Clear is that most of those technologies use a Mathematica Kernel at their core.
Question: Can we assemble a list of acronyms and names of Mathematica related frameworks, technologies or products and add a short and clear description how they relate to Mathematica?
