Web Data Services

This page describes the web services and data provided by the main ​Transition Network website and the ​Sharing Engine.

Directory Services

These services provide lists of core ContentTypes? that can be used to prime or update remote caches and clients.

Initiative Directory Service

Returns a list of initiatives with their basic data and geographical coordinate information. See below for an example

ALL initiatives

• Returns: All initiatives in in the directory - see below for format and example output.
• Usage: To be used sparingly to prime remote cache of initiative data. Use 7 or 30 day update versions for refreshes. This view is cached for 6 hours to reduce performance impacts on the main site.
• Service URL: ​http://www.transitionnetwork.org/transition-services/directories/initiatives/all
• Parameters: None, only three variations of this view exist - 'all' and updated within 7 or 30 days versions.

Initiatives updated within 30 days

As above except:

• Usage: To be used whenever a client needs to refresh their cache, unless the time since last update less than 7 days in which case use the version below, or more that 30 days in which case get ALL again. View cached for 6 hours.
• Service URL: ​http://www.transitionnetwork.org/transition-services/directories/initiatives/updated-month

Initiatives updated within 7 days

As above except:
