Each meta module represents an improvement made to the module by one of the major four races for their own use. Example: I'm pretty sure the "Regard" Energy Transfers are Amarr, and the "Partial E95" ones are Caldari.The answer to this question is that I've read this a couple of times over the years, but went looking for a reference when I wrote the "Meta on meta" blog entry and couldn't find one. I'm still pretty sure of my facts here, though. I'd appreciate it if someone has the source at their fingertips, though!
In the meantime, I'm sure that all the "model number" type names are Caldari ones and reflect their "not poetic, just practical" nature. So the J5 and J5b point/scram are theirs. All of the blue ECM mods are also theirs. This would make missile launchers like the TE-2100 theirs also, as well as the N-Type armor hardeners and C5-L shield boosters.
Amarr names, by contrast, are the most flighty and poetic. Look at Amarr ECM mods and you'll see they go from 'Penumbra' to 'Gloom' to 'Umbra', reflecting increasing levels of darkness. The "Fleeting" warp disruptors and scrams are theirs, and all of the Warp Core Stabs are theirs. The "Solace" armor reppers are also theirs.
Minmatar names are just descriptive of what the module does, like they're trying to include a manual right in the name. ;-) The "Faint" scrams and points are theirs, as are the "Supplemental Barrier" shield extenders and the "Inefficient" armor and hull reppers. All of the meta ABs and MWDs are of Minmatar origin, as are all of the meta Target Painters (check the acronyms of their names, if you haven't already).
The Gallente names are just goofy. If you can't figure out what the name of something is trying to say, that's the Gallente one. I like to imagine the mod names were all mistranslated from the original French and make total sense in that language. In English, not so much. These are things like "Compulsive" jammers and "Azeotropic Ward Salubrity" shield extenders and "Carapace Restoration" armor reppers (OK, that one makes a small amount of sense). I'm pretty sure all of the Projected ECCM mods are Gallente.
Finally, which race gets the meta 4 mod for each type of mod usually makes pretty good sense, too. The meta 4 (Solace) armor reppers are Amarr. The meta 1 (I-a) armor reppers are Caldari. The meta 4 hull reppers are Minmatar, of course. The best shield extenders, shield boosters, and shield transporters are Caldari. Sometimes, as I've already noted, a given race makes all the meta gear for a particular type of mod.
But no, I don't have a written, canon source for any of this. I just remember reading it a couple of times. Can anyone point to a source?
