Brainstorming experimental / undeveloped / rejected ideas for microformats-2.
further simplifications
more on allow root class name only
name default property on all
- pick 'p-name' (per feedback from microformats mailing-lists over the years, Google Rich Snippets renaming, etc. as better to use 'name' instead of 'fn' - benefits outweigh costs) as the single required and thus implied property of *every* microformat. that is, make this part of the syntax - we're marking up proper nouns.

use-cases: every single proper noun on any web page.
to-do: try examples with organizations, events, products (however note that those are almost always capitalized thus implying proper noun / name semantics)
imply url property from root only a href
- imply 'u-url' property from a root class name only on an <a href>
E.g.
<a class="h-card" href="http://chrismessina.me/">Chris Messina</a>
parses as:
- microformat: h-card
- implied 'name' from root element contents: Chris Messina
- implied 'url' from a href: http://chrismessina.me/
use-cases - nearly every link to a person ever like on blog posts, blog rolls etc. all the same data/use-cases that informed XFN.
to-do: try examples with organizations, events, products
imply name and photo properties from root only img
- imply 'u-photo' property from a root class name only on an <img src alt>
E.g.
<img class="h-card" src="http://example.org/pic.jpg" alt="Chris Messina" />
parses as:
- microformat: h-card
- implied 'p-name' from img alt: Chris Messina
- implied 'u-photo' from img src: http://example.org/pic.jpg
use-cases - nearly every social networking site that shows a grid of people without text already does so with img tags and their names in the alt attribute. most of those are linked too, which brings me to the next imply:
to-do: try examples with organizations, events, products
imply name and photo property from img only child of a href
Combining the above:
<a class="h-card" href="http://chrismessina.me/">
<img src="http://example.org/pic.jpg" alt="Chris Messina" />
</a>
parses as:
- microformat: h-card
- implied 'u-url' from a href: http://chrismessina.me/
- implied 'p-name' from img alt: Chris Messina
- implied 'u-photo' from img src: http://example.org/pic.jpg
use-cases - nearly every social networking site that shows a grid of people without text already does so with hyperlinked img tags and their names in the alt attribute.
to-do: try examples with organizations, events, products
rejected ideas
n prefix for multiple numbers
Idea:
- "n-*" for (one or more) numbers, e.g. "n-rating", "n-geo", leaving the semantics of more than one number up to specific format. e.g. for an "n-rating" inside an "h-review", the first number would presumably be the rating value, when only two numbers the second would be the "best" value (e.g. rated
<span class="n-rating">3 out of 4</span>), when three numbers the second would be the "worst" and the third would be the "best" (e.g.<span class="n-rating">7.5 out of 1 to 10</span>). similarly "n-geo" would specify the first number to be the latitude and the second to be the longitude.
Rejected because while this *might* work for some properties in *English* it will NOT localize/internationalize well (orders of numbers in phrases change in different languages), and it will also limit the human expressivity of the plain text. Thanks to Ben Ward for this feedback at the 2011-06-02 microformats dinner. Tantek 14:25, 9 June 2011 (UTC)
