PlaceCal big picture

The basic concept of PlaceCal is to connect people who run events within their community to people within communities looking for things to do.

A high level view of how it works looks like this:



  • Neighbourhoods are hierarchical, so wider area neighbourhoods can contain narrower scoped neighbourhoods. This information comes from the UK government. Sites manifest as domains in PlaceCal- so a Birmingham site would have birmingham.placecal.org
  • Site admins can assign neighbourhoods to their site.
  • Partners are people who run activities. They have an address which we use to look up the corresponding neighbourhood.
  • Events represent a point-in-time that a Partner is running an activitity, so basically a Date/Time.


Sites contain many Neighbourhoods. Partners have many Events. The events are created in PlaceCal from a Calendar that imports the event data from the Partners online calendar source (meetup, eventbrite, facebook, ICS and XML).


Broadly there are two types of user:

  • Public Users: people who visit x.placecal.org to see events/partners in their area
  • Partner Admins: people who create Partners so they can import events to provide activities on sites for public users.

Ultimate data flow

Sites have two sets of data

  • Partners (in the sites neighbourhoods) that are pulled by Partner -> Address -> Neighbourhood -> Site
  • Events (happening in Site neighbourhoods) that are pulled by Event -> Partner -> Address -> Neighbourhood -> Site
