Is there any source of spell info that is more easily searchable than wowhead?
For example, if I want to write an add-on that needs to be aware of mutually exclusive buffs and debuffs. I certainly don't want to have to maintain that info by scanning message forums and monitoring for changes.
It would be much better if I could, for example, query a database to find all spells that increase attack power.
all database addons/libs that i know of rely on wowhead to get their info (if its not easily available via the client at run time). most of these maintain their databases via a "miner" (script that can be run that will go to wowhead and parse/mine all the relevant info and spits out a lua file ready for use)
be aware of the fact that wowheads database is not always complete or 100% correct. for example it currently does not have any mining nodes for the new hyjal zone (thats why gathermate2_data is missing them as well)
