Have you considered making the "LibInstanceLootData-1.0" thing this uses into a real library with a separate public repository? Or instead, just change the 2 files current extract path from a unique path location to to the root folder? As in removing the "LibInstanceLootData_data-1.0" references from data.lua & lib.lua and just making them mod-specific files. As AtlasLoot and some others do it with their built-in databases.
As it is, there doesn't seem to be a point to having those two files packaged as a library (with different path outputs). Other devs can't access it/them easily if they want to use those files in their mods (as a library). As well as it being a hassle to users/testers who normally run libraries disembedded. Does it make data mining runs easier or something as they are?
thoughts i had when moving those files into a lib folder:
I am thinking of splitting the dropinfo on item tooltips into its own addon and thus would require a shared yet independent database. As such when i rewrote the wowhead miner, last time it broke, I also broke out all the data access functions to parse the data and made sure it could upgrade itself when more than one version was loaded (YAY libstub). As such it is more a library than just some data so I tossed it in the lib folder.
I am not entirely sure if i want to make it into a standalone Lib, unless there is demand from others (also someone else with more programming experience should look through the lib code to make sure it is all good before releasing it imo), but i am open to it :)
