📅 An event is a type of post that in addition to a post name (event title) has a start datetime (likely end datetime), and a location.
For information on IndieWebCamp events themselves, see:
Why publish indie events
You should post events on your own site to own your events and so your friends with indieweb sites can directly RSVP to you (as well as post invitations to others) without depending on a silo to mediate your event related interactions.
Why POSSE events
How to markup
Event posts must be marked up with h-event.
Optionally they can be wrapped in an h-entry as well (though it's not clear this is necessary). Parsers should be prepared to handle events without an h-entry tag.
(sample event post markup with a top level
h-event would be nice!)
How to provide an RSVP UI
Event posts should have webaction buttons for RSVP actions and inviting others. E.g. some subset of:
[ Going ][ Maybe ][ Interested ][ Can't Go ][ Ignore ][ Invite ] perhaps based on private vs. public events, if you've already RSVPd, or relationship with the person.
See Facebook's RSVP UI:
How to accept RSVPs
How to accept invitations
How to limit capacity
Some events have limited capacity and want to offer "tickets," ie only accept the first N RSVPs.
To do this, the site that hosts the canonical h-event should set the capacity. When it renders the event, it should show the space remaining based on its current number of
It should handle RSVP webmentions for the event in serial. When it gets a
yes RSVP, it should check the capacity against the current number of yes RSVPs. If the event is full, it should reject the RSVP webmention. This could be done with either an explicit 403 Forbidden, or an implicit status like 203 Non-Authoritative Information or 304 Not Modified along with a human-readable message saying the event is full.
The host could also put overflow yes RSVPs on an ordered waiting list, mention that in the reject message, and automatically upgrade people on the waitlist when existing yes RSVPs are withdrawn.
In implementation order:
Ben Werdmüller uses idno on werd.io to post events since 2013-06-25 (right after IndieWebCamp 2013!), which automatically accept RSVPs from other sites using RSVP webmentions. Events may also be replied to in the same manner as notes and articles. E.g.
- index page of upcoming/recent events: http://werd.io/content/events
- http://werd.io/2013/an-indieweb-catchup-over-food-and-drink (with example of explicit visible invitations)
- index page of recent events: http://aaronparecki.com/events
Bret Comnes has implemented events inside of jekyll for bret.io since 2013-07-25. It supports receiving webmentions, but does not parse responses for RSVP status or display reply contexts at the moment. Example:
- (bad) Example of data https://raw.github.com/bcomnes/bcomnes.github.io/master/_posts/notes/2013-07-25-t1.md
The event data is stored in the YAML which separates the final layout and the event data. A form is used to assist in creating the event post via prose.io.
Jeena Paradies has implemented events on his website because he wanted to host HWC:s and it wouldn't look good without the possibility to RSVP to a indie event. The event page receives RSVP:s and displays them under the event. Example:
- https://snarfed.org/2014-06-16_homebrew-website-club-at-quip (includes native and backfeed rsvps)
- Posted 2014-06-16, for an event on 2014-06-18
- POSSE FB event: https://www.facebook.com/events/675481332531191/
- Tweet about: https://twitter.com/schnarfed/status/478564735265157120
- G+ post/linkshare about: https://plus.google.com/+RyanBarrett/posts/JwiJAfBNs9w
- Both tweet and G+ posts worked as proxy POSSE posts for Bridgy backfeed interactions (favorites, retweets, +1s etc.)
- POSSE facebook copy: https://www.facebook.com/events/736605033092500/
- More recent event: https://kylewm.com/2015/04/homebrew-website-club-1
- has fixed the duplicate display of "is going" colored text vs. "is attending." default text summary from Bridgy (which the above 2014 example has)
gRegor Morrill added event posts (sans RSVP) on 2015-10-01. Example:
- h-feed of upcoming events: http://gregorlove.com/events/
- h-feed of past events: http://gregorlove.com/events/past/
- Immediate use-case is that I want to log all concerts I attend.
- All events: http://veganstraightedge.com/events
- Single event: http://veganstraightedge.com/events/2013/11/02/farmhouse-conf-5-collapse
The following people either strongly want to implement events on their site, or are in the process of doing so, you may find some implementation clues in their notes
Tantek Çelik: event posts are a pretty big itch for me, but also a lot of specific work:
Prototype event as a note:
- with: name, datetime start, time end, how to RSVP
- POSSE tweet copy: https://twitter.com/t/status/403064607373537280
- I'm going to work with jarofgreen to get webmentions in opentechcalendar (since most events, at least ones I attend in scotland, are on there, and if they're not I can add them)
- then do all my events through that
- and rsvp from my site
- longer term hopefully we can get something working so I can post an event on my site initially
- POSSE (perhaps by sending a webmention) to opentechcalendar and have it create a public event copy
Calum Ryan added event posts on 2016-06-15. Open to RSVP via same Webmention.io Jekyll Plugin that's present for all blog posts. Further work planned to possibly separate RSVP from other replies.
- with name, datetime, location, start, time end
As ideas here are implemented, they should be moved to actual sections of their own with links to examples.
Typical silos event posts (e.g. Facebook, Google+) provide (encourage) the option of an event image - used as a header for the event. This header is used at the top of the event permalink page, and also often shown in an event list view (e.g. on Facebook).
Such header images are often quite a good visual/emotional draw for the event. Header images are typically representative of the event, sometimes displayed with the name of the event superimposed on top.
If you're posting events, consider providing this option for yourself (in your event posting UI or otherwise as part of your publishing system) as part of your indieweb event posts as well.
Since the photo would be deliberately chosen to represent the event, we could extend h-event to represent the photo as well with:
u-featured(re-used from h-entry).
u-featured is more appropriate for a header image than
u-photo, since u-photo really should be used for photos of the event itself, taken at the event (We are now doing this with Homebrew Website Club photos, which gets them included in this-week in the IndieWeb).
In particular, on event posts, the location is shown *first* as a centered dot in a wide and short rectangle map that shows the local area, and then second underneath as text address.
Showing a map and showing it early is both visually striking and instantly provides a sense of "is this near me", or "is this near somewhere I'd like to be or might be anyway". It quickly gives you context in a way that a purely textual address does not.
A horizontal map (banner map?) from a Facebook event:
There are two typical existing approaches to displaying RSVPs:
- clustered by state (yes, no, maybe) - current silos do this - see below
- in time order regardless of RSVP state
Clusters are typically displayed as facepiles, either entirely, or abbreviated at some fixed number with a method to expand / view the whole set.
Time order presentation usually include some text about the RSVP, e.g. "is going", "is attending"
Every event silo by default shows who else is has RSVPed that yes they're going, and more so, often first display who you know that's going to the event. Quickly seeing "who else is going" or might go or is invited is a huge sense of context/comfort as well, especially with little face icons.
E.g. Facebook clusters (potential) attendees by:
(and declined is typically hidden)
More screenshots needed
Event attendees on Facebook:
Note the going/maybe/invited sections on FB first show *only* those you know (if any), and *only if* there's no one you know in a section, does the section show 5 icons of others who said they're going/maybe or were invited. In either case, the order of icons is most recently responded/invited first.
Public events don't necessarily have a public list of invited users, depending on the system, but nonetheless list attendees. For example, on Plancast:
Plancast only shows invitees on an event to the event organizer, i.e. when the event organizer themselves is looking at the event permalink page.
People like being explicitly invited to events. One way to send invitations with indieweb events is:
- Add people explicitly to an invited list on the event (present on the event page as noted above in Attendees) - with icon and name linked to their home page.
- Send webmentions to their home page from the event permalink.
The idea is that a person's site's webmentions queue sees webmentions from the event to the home page and interprets that as an invitation to the event. If needed we could add some markup like
class="p-invitee h-card" to the event page so that consuming applications could tell the difference between mentions and invitations of people.
Also see indieweb messaging, which also uses a webmention to the user's homepage.
How and where should event posts be POSSEd?
- Related: RSVP: POSSE
Event-aware destinations to consider:
POSSE to Eventbrite
Eventbrite - has best API for creating events, getting updates, perhaps backfeeding attendees etc.
- Bridgy feature request: publish Eventbrite events
- Lots of people seem to use Eventbrite
- It seems to be good at getting people to show up to events - e.g. with reminders etc.
- Eventbrite also emails people when some number (2+?) of their friends are going to an event.
POSSE to Facebook
Facebook - likely has broadest reach of people you might want to explicitly invite
- Currently the Facebook API disallows creating, updating, or deleting events
- Creating a manual POSSE event copy on FB of an event on your site is still useful!
- people's RSVPs on the FB event can send webmentions to your site via a Bridgy, and thus display people's FB RSVPs *on the event on your site* E.g.
- Aaron Parecki is posting events using p3k on aaronparecki.com and manually POSSEing them to Facebook:
- Ben Werdmüller is posting events using idno on werd.io and manually POSSEing them to Facebook:
- Ryan Barrett is posting events inside article posts on snarfed.org and manually POSSEing them to Facebook:
POSSE to Lanyrd
Lanyrd - has an API for creating events, getting updates, backfeeding RSVPs
POSSE to Plancast
Plancast - event-specific silo
POSSE to Google+
- G+ API doesn't expose events
- when someone shares an event, you can see it in their stream with activities.list and get, but that's just a note about it, not the event itself.
- G+ API bug asking for events: http://code.google.com/p/google-plus-platform/issues/detail?id=567
POSSE to Twitter
Despite not supporting event posts per se, Twitter is worth considering as a POSSE destination.
- Can we compress the details of an event post into 140 characters or less? (117 to leave room for event permalink URL, 116 for https).
- How do we abbreviate what/when/where "fields"? E.g.
- What: summary... (ellipsed)
- Where: @-alias of venue (how do we do venue lookup on Twitter? Perhaps use Foursquare to lookup the venue and see if their venue entry has a Twitter for the venue?
- When: YYYY-MM-DD HH:MM (seems quite long, what's the best way to compress a datetime in a human readable way?)
- CC: @-names (of folks to explicitly notify, like an invitation)
- Should such fields be explicitly labeled e.g. with "What: / Where:" etc. with linebreaks between them?
- Or should we figure out a plain text event serialization format since things like an @-named venue already reads well "at venue"? (see picoformats for prior work/research on this)
- "featured" or map image -> tweet photo?
- Should an event post with a featured/header photo be POSSEd to Twitter as a tweet with a photo?
- Should an event post without a featured/header photo, but with a location, be POSSEd to Twitter as a tweet with a photo which is just a static rendered image of the map view of the venue / location?
- What is the "engagement" or "response rate" is on tweets/events with header photos vs. events without? *guessing* that with photos is much higher
Indieweb sites with event posts (and perhaps even just RSVP posts) could also provide an index of what events they're attending, e.g.
- at a /events URL
From a human design perspective this makes sense as:
- "these are the events I'll be at"
which is likely a union of personal event posts and RSVP yes (and maybe maybes too?) posts.
Kind of like a view of your public calendar of events, regardless of whether you're organizing/hosting or just attending.
Such an events index could be displayed as a list view (similar to the default view of fb.com/events) or as a calendar view (like gCal), or with an option to toggle between them.
An easily-discoverable link should probably be displayed from the user's index or homepage.
- Potential for microformats or microformats-like markup to indicate a user's calendar as linked from their h-card?
Markup for an h-event on a site must include a number of properties to enable presentation and user interaction as implied by some of the above brainstorming, and some of the better silo UX as documented in "Silo Examples"
The following fields/properties are necessary in the markup somewhere:
u-featuredfor an event background photo
dt-start(likely in the future)
- with possible nested object
- with a map
u-url- but how to identify it as a map URL?
- with a map
u-photo- but how to identify it as a map photo?
- with a map
- with possible nested object
p-organizer(reserved h-event property)
h-cardfor who is going
- not sure how to indicate RSVP status for each
p-x-responses h-feed- event activity, e.g.
h-entrys inside for:
- event creation, comments, when RSVPs were received
- TBD after a plain text design
Response context CRUD
Similar to the general reply context: CRUD protocol, when an event changes (name, location, times, description, etc.) you should send webmentions to all the responses to the event that you've accepted, e.g. to all:
- RSVPs in response to your event
- invitations to your event
- and all other generic responses like comments, likes, reposts
What about when an event is cancelled? Options:
- Implement event cancellation as a delete and return 410, based on real world existing silo example:
- Facebook notifies you when an event you've indicated interest in has been cancelled, but then clicking that notification doesn't go anywhere - the event permalink itself just 404s.
- ... other options?

Sometime in 2015, Facebook redesigned their events presentation again, which in many ways seemed to regress even more, especially in the mobile web view:
Mobile Web UI:
Here is what the 2014-02-27 redesign (limited rollout as of that date, but subsequently broadly rolled out) looks like:
Mobile Web UI:
Shall we count the design regressions?
- Global noise in the left column replaces the very relevant and easily skimmable who is going, maybe, invited lists of people
- Big blank area where there is no event header image
- Lots of visual noise from the gray background between the white blocks of text
- Missing the map overview graphic
- Less clear who is going/maybe/invited
- Lack of hierarchy (ordering) of going/maybe/invited removes subtle invitee incentive to upgrade from invited to maybe to going.
- ... more?
This was perhaps the pinnacle of Facebook's event page design.
Facebook has had one of the more interesting/nicer/cleaner event page designs for quite some time.
