17. Stages of hub development
Step 1 (automatic): The elmcity service scans Eventbrite,
Eventful, Facebook, Meetup, and Upcoming for candidate
feeds.
Step 1 yields two outputs:
a) http://elmcity.blob.core.windows.net/manchesteruk/taggable_sources.html is
a page of links
b) http://elmcity.blob.core.windows.net/manchesteruk/taggable_sources.html is
corresponding json

18. Stages of hub development
Step 1 (automatic): The elmcity service scans
Eventbrite, Eventful, Facebook, Meetup, and Upcoming for
candidate feeds.
Step 2 (manual): A human processes the taggable_sources
files: removes junk, adds and tags useful feeds, looks for
related iCalendar feeds.
Step 2 yields a hub like the Manchester UK hub we see today.

19. Stages of hub development
Step 1 (automatic): The elmcity service scans Eventbrite,
Eventful, Facebook, Meetup, and Upcoming for candidate
feeds.
Step 2 (manual): A human processes the taggable_sources
files: removes junk, adds and tags useful feeds, looks for
related iCalendar feeds.
Step 3: The hub is adopted by a curator who works toward
lighting up the iCalendar “dark matter.”
Step 3 has never really happened yet.

20. iCalendar “dark matter” for Manchester UK
http://oddbar.co.uk/odder/
http://www.iwm.org.uk/events/iwm-north
These are web pages with
http://www.stclement-chorlton.org.uk/diary.php#whats
calendars that trap event info
http://www.parrenthorn.co.uk/calendar/
in HTML silos.
http://www.philandaly.com/
http://www.holdengallery.mmu.ac.uk/exhibitions.php
http://www.stannsmanchester.com/whats-on/
All of these could easily be
http://www.bbc.co.uk/showsandtours/events/index.shtml
converted, using Google Calendar or
http://www.therubylounge.com/
Hotmail Calendar or Outlook or
http://www.starandgarter.co.uk/star4/WhatsOn.aspx
Apple iCal or any another standard
http://www.drybar.co.uk/calendar.php
calendar app, to dual use:
http://www.chinese-arts-centre.org/
http://thedeafinstitute.co.uk/calendar.php
1 An HTML/JS widget for the site
http://www.o2apollomanchester.co.uk/
2 An iCalendar feed for syndication

These, and many others, offer calendar modules without iCalendar support.

23. Key messages
- Many public events are published online (as HTML or PDF)
- Few are machine-readable (as iCalendar)
- All could be dual-purposed using standard calendar apps
- The ICS ecosystem could work like the RSS ecosystem
- a pub-sub network
- open, standards-based
- It’s so simple nobody thinks of it
