The 80/20 principle is not meant to be applied this way.
In the end Yes it is, if a property doesn't come within 80% of popular
publishing patterns It doesn't belong in the format that is why the
microformats process is fair.
I think that there is a misunderstanding of 80/20 that is at the core of
your "let's remove all properties that don't have at least 70% coverage"
argument. I'm not sure if it's your misunderstanding or Toby and my
misunderstanding since 80-20 isn't spelled out clearly on the
Microformats wiki, but here goes...
My understanding of the way this community uses 80-20 is like so:
We solve the markup problem for roughly 80% of the websites out there
using 20% of the attributes that could be used to solve the problem.
Correct...
The Pareto principle, states that "for many events, 80% of the effects
come from 20% of the causes"[1].
or from the same source as you cited
The Pareto principle (also known as the 80-20 rule, the law of the vital
few and the principle of factor sparsity) states that, for many events,
80% of the effects come from 20% of the causes
In Microformats this means that if a propery is used more than 80% of
the time then it should be included in the format, this will result in
the top 20% of all discovered properties making their way into the final
Microformat.
Another way to look at it is this:
[...]
Let's clear this up first - as all of your "removal of attributes"
argumentation is based on this premise. Is this everyone else's
understanding of how Pareto is applied to Microformats?
Yes.
Thanks
Martin
