Just some loosely collected thoughts on how to represent gender.
sex and gender identity
A simple proposal is to use a small taxonomy for sex, and freeform field for gender, e.g.
- sex: M(ale) F(emale) O(ther) N(one or Not applicable)
- gender-identity: string
A shorthand or compound property "gender" could be created to represent both, while leaving the freedom of personal expression.
A compound "gender" property could be used like this (using the "Dude" alternative gender label from Pownce/Digg in the gender examples page).
<span class="gender"> <span class="gender-identity>Dude</span> (<span class="sex">male</span>) </span>
