Editing WoW:TradeSkillLink (section)

== Recipe list ==

The recipe list portion of the tradeSkillLink is a bitset representing which recipes are available.

'''Example'''

If the recipe list portion of a tradeSkillLink is:
 ZAAAAAAAgAAAAAAAgAAAAA

Then the recipe list bitset is:
 100110000000000000000000000000000000000000000000000001000000000000000000000000000000000000000000000001[... zeroes]

This set indicates that four (4) specific recipes are available (note that there are 5 bits; there is no information on why there is an extra bit at this time). Also note that the bitset is unique for each tradeskill; a recipe denoted by bit N in one tradeskill is not the same as a recipe denoted by bit N in another tradeskill.

The bitset is encoded into standard [http://www.hcidata.info/base64.htm Base64], using the characters A-Z, a-z, 0-9, +, and /. Being Base64, there are 6 bits per digit (similar to how hexadecimal has 4 bits per digit); this allows one to easily determine if a specific bit is set by looking only at a single digit in the string.
