Example

Here is a simple event example:

<div class="h-event">
  <h1 class="p-name">Microformats Meetup</h1>
  <p>From 
    <time class="dt-start" datetime="2013-06-30 12:00">30<sup>th</sup> June 2013, 12:00</time>
    to <time class="dt-end" datetime="2013-06-30 18:00">18:00</time>
    at <span class="p-location">Some bar in SF</span></p>
  <p class="p-summary">Get together and discuss all things microformats-related.</p>
</div>

Parsed JSON:

{
  "items": [
    {
      "type": [
        "h-event"
      ],
      "properties": {
        "name": [
          "Microformats Meetup"
        ],

          "Some bar in SF"
        ],
        "summary": [
          "Get together and discuss all things microformats-related."
        ]

}

Get started

The class h-event is a root class name that indicates the presence of an h-event.

p-name, dt-start, dt-end, p-location, p-summary, and the other h-event property class names listed below define properties of the h-event.

See microformats2-parsing to learn more about property class names.

Properties

h-event properties, inside an element with class h-event:

Experimental properties currently in use in the wild but not (yet) part of the official h-entry spec:

All properties are optional.

Status

h-event is a microformats.org draft specification. Public discussion on h-event takes place on h-event-feedback and the #microformats irc channel on irc.freenode.net.

h-event is ready to use and implemented in the wild, but for backwards compatibility you should also mark h-events up as classic hCalendar events.

Property Details

(stub, to be expanded)

p-location

p-location is typically a physical address, optionally marked up with h-adr, for example:

<p class="p-location h-adr">
  <span class="p-street-address">17 Austerstræti</span>
  <span class="p-locality">Reykjavík</span>
  <span class="p-country-name">Iceland</span>
</p>

Backward Compatibility

Publisher Compatibility

For backward compatibility, you may wish to use classic hCalendar classnames in addition to the more future-proof h-event properties, for example:

<div class="h-event vevent">
  <h1 class="p-name summary">Some great event</h1>
</div>
</div>

Parser Compatibility

Microformats parsers SHOULD detect classic properties only if a classic root class name is found and parse them as microformats2 properties.

If an "h-event" is found, don't look for a "vevent" on the same element.

Compat root class name: vevent
Properties: (parsed as p- plain text unless otherwise specified)

iCalendar Compatibility

hCalendar-specific implementations that perform custom display or translation to iCalendar .ics SHOULD prefer p-name over p-summary, and use p-summary value(s) as a fallback if there is no p-name.

Background

This work is based on the existing hCalendar and iCalendar specifications.
