hCalendar Example 1 Steps
This is a step by step explanation of the first example in the hCalendar specification.
Example
Here is a sample event in iCalendar:
BEGIN:VCALENDAR PRODID:-//XYZproduct//EN VERSION:2.0 BEGIN:VEVENT URL:http://www.web2con.com/ DTSTART:20051005 DTEND:20051008 SUMMARY:Web 2.0 Conference LOCATION:Argent Hotel, San Francisco, CA END:VEVENT END:VCALENDAR
and an equivalent in hCalendar:
<span class="vcalendar"> <span class="vevent"> <a class="url" href="http://www.web2con.com/"> <span class="summary">Web 2.0 Conference</span>: <span class="dtstart">20051005</span>- <span class="dtend">20051008</span>, at the <span class="location">Argent Hotel, San Francisco, CA</span> </a> </span> </span>
which could be displayed as:
Web 2.0 Conference: 20051005-20051007, at the Argent Hotel, San Francisco, CA
Note 1: The product information is not necessary since hCalendar is an interchange format. When transforming hCalendar back into iCalendar, the transforming engine should add its own product ID.
Note 2: A surrounding element is optional, and can be left out as such. It is optional since the context of a vcalendar is implied when a vevent is encountered. The implied context/scope is that of the document. Authors may explicitly use elements with class="vcalendar" to wrap sets of vevents that all belong to the same calendar, e.g. when publishing multiple calendars on the same page.
Note 3: The version information is unnecessary in hCalendar markup directly since the version will be defined by the profile of hCalendar that is used/referred to in the 'profile' attribute of the <head> element.
Note 4: ISO8601 dates are however not very human friendly. Not only that, in the case of the end datetime (DTEND), the date must be specified as a whole day after the last day since DTEND is exclusive! In addition, the year is often understood implicitly by humans from the context. Thus this example could be improved by using <abbr> to make the date information more human readable and friendly, e.g.
<span class="vevent"> <a class="url" href="http://www.web2con.com/"> <span class="summary">Web 2.0 Conference</span>: <abbr class="dtstart" title="20051005">October 5</abbr>- <abbr class="dtend" title="20051008">7</abbr>, at the <span class="location">Argent Hotel, San Francisco, CA</span> </a> </span>
which could be displayed as:
Web 2.0 Conference: October 5-7, at the Argent Hotel, San Francisco, CA
Back to the hcalendar specification.
