Open Web Camp IV

Open Web Camp IV (#owc4) - featuring a session on microformats-2:

microformats are published on millions of sites, providing a standard simple API for the data on those pages with no additional URLs, file formats, callbacks etc. Similar approaches have been tried as well (e.g. RDFa, microdata).

Lessons learned over 8 years have been incorporated into new HTML5 elements and microformats 2.0 for better accessibility, more efficient markup, improved semantics and a direct mapping to JSON for API and other data consumers.
