With all of the discussion about iso dates being unreadable and that an
iso date isn't necessarily required when someone enters a date (i.e.
saying 24th June doesn't translate into a single date, neither does
'thursday'). Shouldn't the focus be on trying to standardise date
formats rather than trying to hide the iso date? If we can get a parser
to recognise 'human readable' dates (which *is* possible, if not totally
easy, http://labix.org/python-dateutil for a python version).
I disagree. If you try to make other, human readable formats into a
standard, they will fall short when it comes time to internationaliz (s)e
it. If you can come up with a better format readable to all machine and
all humans in all languages, I'll recant.
I think the ISO 8601 is the best machine data format for the job. I just
don't think it should be in abbr.
So as machine-readable information shouldn't be presented in a
human-readable manner, that rules out having the information in-the-clear,
and in title tags.
This leads us to having a hidden class for machine-readable information that
will be hidden by default and not presented to people.
A class with a suitable name would have to be used, something like the
existing "value" but modified to infer that it's for the computer only and
isn't to be read.
What if the value class was to be used with a hidden class. Then they would
serve their purpose, they wouldn't interfere with existing styles and could
be interpreted correctly.
.hidden {display: hidden}
Then the human-readable and machine-readable can be mashed together. If the
screen-reading software honor hidden styles this could be the right path to
take.
