hCalendar Implementations

This page is informative.

The following implementations have been developed which either generate or parse hCalendars. If you have an hCalendar implementation, feel free to add it to the New Implementations section.

Authoring

Implementations you can use to author, create, and publish hCalendar events.

Blogging and CMS tools

Midgard CMS: Midgard CMS - net.nemein.calendar - as blogged by Henri Bergius

Drupal module: Drupal Upcoming.org syndication module emits hCalendar
MovableType and WordPress plug-ins: StructuredBlogging is a set of plugins for WordPress and for MovableType that supports embedding hCalendar and other microformats in templates and blog posts.
Textpattern plug-in: pnh_mf is a plugin for Textpattern that supports embedding hCalendar and other microformats in templates and blog posts. Written by Chris Casciano.

Browser scripts and plug-ins

Browser plugins that work with existing authoring tools:

Any browser with javascript and a little bit of CSS: microformats.org hCalendar creator (see also original: Ryan King has an hCalendar creator).
Firefox Greasemonkey user script hCalendar creator: magic_hcalendar Greasemonkey user script by Les Orchard - allows easy form entry of an event into any textarea, e.g. into a blog post text area.
Firefox Greasemonkey user script hCalendar to Google Calendar: Elias Torres has created a simple script that will parse hCalendar entries and create a link to add event to Google Calendar's service. Based on George's and Arve's work.

Desktop Authoring Tools

Dreamweaver Extension: Extension suite for Dreamweaver 8 from the Web Standards Project.
xfy

In xfy Community, there are some hCalendar implementations.

hCalendar via RSS parses an RSS feed, retrieves XHTML documents linked from that feed, and syndicates hCalendars into a calendar view.
hCalendar Marker XVCD helps to mark up an event information in XHTML document with hCalendar.
Simple RDF Calendar XVCD is a schedule tool which uses RDF Calendar format. It also converts RDF Calendar format to iCalendar and hCalendar format.

Search and Discovery

Technorati Microformats Search indexes hCard, hCalendar, and hReview as announced by Tantek.
Microformats Bookmarklet is a bookmarklet designed for Safari (works in Firefox and Camino) that overlays on the current page to allow users to import individual hCards or hCalendars. Written by Remy Sharp.

Conversion and Import

Implementations you can use to importing into a Calendar Application, typically by converting hCalendar to iCalendar/vCalendar.

Web Services

These return iCalendar (.ics) and other calendar formats for easy importing into typical calendar programs or other processing.

Technorati Events Feed service uses X2V library to parse hCalendar and return iCalendar (.ics).
- Note friendly URL, e.g. http://feeds.technorati.com/events/http%3A//microformats.org
X2V parses hCalendar and produces a .ics (iCalendar) stream.
- Note: needs to be updated to track changes in the specification as they occur.
Spanning Salesforce produces hCalendar-enabled RSS feeds and .ics calendars from Salesforce.com.
MySpace Events RSS Creator creates RSS feeds of MySpace events with hCalendar markup.

Firefox Greasemonkey Plugins

George has built a Greasemonkey user script that detects hCalendar events and allows users to easily add them to their calendar application(s).
Martin Rehfeld has updated the work of David Janes and produced a Greasemonkey script that finds many microformat elements, including hCalendar events, and provides a popup menu of actions. The hCalendar to vCalendar conversion is done internally within the script. This will work with FireFox 1.5+/GreaseMonkey 0.6.4+ now.

Aggregators

Extract Microformats is a script for NetNewsWire that supports extracting hCard and hCalendar data in blog posts (via Technorati service). Written by Chris Casciano
Endo, an OS X aggregator, supports discovering hCalendar and adding those events to iCal. Look at the last screenshot at the bottom of the page.

Browsing

Implementations that detect, display and otherwise highlight hCalendar events in pages.

In xfy Community, there are some hCalendar implementations. "hCalendar via RSS" parses an RSS feed, retrieves XHTML documents linked from that feed, and syndicates hCalendars into a calendar view.
JSCalendar parses hCalendar and produces a displayable HTML table/CSS-based calendar.

Firefox extension

Tails is a Firefox Extension that will display the presence of microformats (hCard, hCalendar, hReview, xFolk) on a webpage.

Pending

ReminderFox have hCalendar import on their "to do " list.

Flock extension

Flocktails - port of Tails extension for Flock 0.5.12 that looks for hCards, hCalendar, xFolk and hReview and tosses them into a handy topbar

Libraries

Open source libraries of hCalendar parsers and other related code for building hCalendar implementations.

Javascript: simple hCalendar parser by Arve Bersvendsen
PHP

Microformat Base is an open-source PHP microformat aggregation crawler, currently recognizing hreview, hcalendar, and hcard (Source code no longer available as of 6 Dec 06).
phpMicroformats is a PHP class library that generates microformats for calendar events (hCalendar) and vcards (hCard).
hCalendar profile for the hKit parser.

Ruby uformats: is a ruby library that can parse hCalendar, hCard, hReview and rel-tag
XSLT

X2V is available as an XSLT library
palmagent by User:DanC includes toICal.xsl and test materials; it works much like xhtml2vcal.xsl in X2V. See also: RDF Calendar workspace with icalendar test materials.

Potential implementations

These are open source projects that could be potentially enhanced to support hCalendar.
