Microformats, Building Blocks of the Semantic Web

lowercase semantic web

SAME THING

Designed for humans ﬁrst and machines second, microformats are a set of simple, open data formats built upon existing and widely adopted standards. Instead of throwing away what works today, microformats intend to solve simpler problems ﬁrst by adapting to current behaviors and usage patterns (e.g. XHTML, blogging). http://microformats.org/about

Drag API Pitch Here

feeds used to be for geeks auto-discovery in browsers changed that

xhtml xml

microformats xhtml xml

microformats xhtml patterns

microformats elemental µf patterns

compound µf elemental µf patterns

design patterns posh pieces of the puzzle

class “general purpose processing by user agents”

rel describes link relationships

rev describes reverse link relationships

rev is falling out of favor :(

those 3 are all you need not one of them was a tag, all attributes

abbr human-friendly meets machine-readable

datetime abbr with a dash of ISO8601

<%= @time.utc.iso8601 %> <abbr title=quot;2007-10-02T19:00:00-0500quot;> Oct 2 @ 7pm</abbr>

include DRY, reuse content already on the page

hReview hReview hReview

item hReview hReview hReview

elemental microformats the middle siblings

the easiest microformat evar starting small…

rel-home links to the home page

<%= link_to 'Home', root_url, :rel => 'home' %>

rel-license links to the content license

<%= link_to 'Terms', license_path, :rel => 'license' %>

rel-enclosure links to a download

<%= link_to 'Download', @file.public_filename, :rel => 'enclosure' %>

rel-tag links to a tag for the current page

pitfall

what is the tag here? <a href=quot;http://technorati.com/tag/techquot; rel=quot;tagquot;>fish</a>

what is the tag here? <a href=quot;http://technorati.com/tag/techquot; rel=quot;tagquot;>fish</a> tag

what is the tag here? <a href=quot;http://technorati.com/tag/techquot; rel=quot;tagquot;>fish</a> tag irrelevant

rel-* relies on the URL not the text of the link

good tags == pretty urls 42 < 42-tech < tech

<a href=quot;http://technorati.com/tag/techquot; rel=quot;tagquot;>fish</a> tag irrelevant

<a href=quot;http://technorati.com/tag/techquot; rel=quot;tagquot;>fish</a> tagspace tag irrelevant

xfn human relationships as hyperlinks

xfn vocabulary Identity Professional Geographical me co-worker co-resident Friendship colleague neighbor contact Romantic Family acquaintance muse child parent friend crush sibling Physical date spouse met sweetheart kin

<%= link_to @adam.name, @adam, :rel => 'friend met colleague muse' %>

compound microformats center of attention

the main wiki pages are specs specs are great for parsers, not publishers

start by using the creators http://microformats.org/code/
