Schema Editor solutions

[Neutronboy]

I was wondering if anyone knew a place / site / forums where one can gain a better development understanding of creating a custom schema ? I am able to muddle through most concepts, but would love to learn the ins-and-outs of creating a fully fledged custom schema - one that has several hierarchal levels, and utilizes all the necessary parameters.

Thanks in advance.

PS: Is the openLDAP seminar on a bi-yearly event in Europe ?
