Hi,
As Reza mentioned, some specs can be used standalone in SE, and as Wayne mentioned "Jakarta" is the brand, and finally as Werner mentioned "Jakarta" can exactly stand-in for "Java" in the existing abbreviations (whether we should let eventually go of those is another matter, of course).
So given all those insights the simple Jakarta prefix might indeed work best.
"Jakarta EE" is then the name of the various Jakarta specs (APIs), so the last list again with Jakarta EE added:
Jakarta EE - All the specs further in the list
Jakarta Security - JSR 375
Jakarta Batch - Jbatch
Jakarta Transactions - JTA, retroactively meaning Jakarta Transactions API
Jakarta Validation - BVal
Jakarta Authentication - JASPIC, retroactively meaning Jakarta Authentication SPI for Containers
Jakarta Authorization - JACC, retroactively meaning Jakarta Authorization Contract for Containers
Jakarta Concurrency - CUJ, retroactively meaning Concurrency Utilities for Jakarta EE
A few names are as mentioned a bit more difficult, but *perhaps*:
Jakarta MVC - JSF, retroactively meaning JakartaServer Faces
"Servlet" is a somewhat unique name without an abbreviation. Once used as the opposite of Applet, which has finally been forgotten. Could perhaps simply officially become:
Jakarta Servlet - Servlet
Kind regards,
Arjan
