tRendezvous Twitterformat Proposal
@user /rsvp URL [yes|no|cancel]
- URL: URL to a page that contains an hCalendar entry
- [yes|no|cancel]: (Optional) Whether or not you can attend the meeting referenced in the URL. The "cancel" value is used to cancel an existing RSVP.
The tRendezvous Twitterformat (e.g.,
@aral /rsvp http://bit.ly/yogaclassbrighton) is used to arrange meetings. The preceding example asks Aral if he wants to attend Jenny's Yoga class on December 14, 2009 from 7:30pm-8:30pm at the Brighton Media Center. The meeting information is contained in the target URL in hCalendar format. Aral can then respond with either
@yogajenny1 /rsvp http://bit.ly/yogaclassbrighton yes or
@yogajenny1 /rsvp http://bit.ly/yogaclassbrighton no depending on whether or not he can make it. A Twitter client that implements tRendezvous can, for example, create an entry in the user's iCal when they confirm attendance at a meeting. User may cancel existing RSVPs by passing "cancel" as the second argument (e.g.,
@yogajenny1 /rsvp http://bit.ly/yogaclassbrighton cancel).
Tweets lack semantics. Twitter doesn't know or care whether I am asking someone to see a movie with me or telling them that I just won the lottery. The tRendezvous Twitterformat adds semantics to Twitter by defining the format of a meeting request. It also uses the web by requiring a URL to a web page that contains the meeting details in the hCalendar microformat.
The tRendezvous Twitterformat is simple enough to be used manually by users. e.g.,
@aral /rsvp http://bit.ly/yogaclassbrighton
i.e., Aral, would you like to attend my Yoga class on December 14, 2009 from 7:30pm-8:30pm at the Brighton Media Center?
@yogajenny1 /rsvp http://bit.ly/yogaclassbrighton yes
Implementation guide for Twitter client authors
No special implementation is necessary (or practical). The user can type the tRendezvous tweet herself.
Presenting the question
- Parse the hCalendar entry at the URL
- Display the meeting details along with Yes and No buttons for the user to respond
- When the user responds, create a tRendezvous tweet with "yes" or "no" at the end, depending on the user's response.
- Create an iCal entry in the user's calendar application to save the meeting.
Handling the response
- If the response is "no", simply display it to the user in a manner that links it to their original tRendezvous tweet
- If the reponse is "cancel", cancel the existing meeting calendar entry and alert the user.
- If the response is "yes", parse the hCalendar entry at the URL and create an iCal entry in the user's calendar application to save the meeting.
