Did that last email go through fine? I sent it as HTML to hopefully get the
symbol right, so it may have b0rked for a few folks.

I talked this over with some friends of mine, (mathematics PHD candidate,
astronomy PHD candidate w/ BS in physics, and a candidate in computer E) and
here is what they came up with.
The way to express a number exists in a specific range is:
x ? [y,z]
This is the only existing standard that I know of, and it is extremely
common in mathematics, so I think it is the only thing that can be pulled
from. The use of the "element of" symbol greatly complicates matters, and
should be unnecessary in the context, so I would suggest it be dropped
The format I would suggest is:
So in practice, to represent a rating of 4.3 in a range of 1 to 5 inclusive
With the lower limit dropped as a default value:
And with the lower and upper limit dropped as default values:
Then placing this in the TITLE attribute would allow the content creator to
include the information in a way that isn't immediately visible to the end
user, but still available. To use an example from my earlier email:
<img src="stars-2-0.gif" />
<img src="stars-2-0.gif" class="rating" title="2 [0,5]" />
It should also be easy to write, and for a parser to grab the information
from the document, keeping in line with the "enable decentralized
development of resources, tools..." goal of microformats.
The only part of Microformats design goals that I'm not sure about is "human
readable". I have personally taken Calculus classes (one recently), so it
immediately was clear to me what the idea meant, being something that was
oft used there. But I'm not sure that the average person would make the
What were people's impressions when they read it? Did it make sense, or was
it too obfuscated? Is there a better way to simplify it further that would
make more sense?
