Changes Feed

Resource Map exposes a way for other services and programs to subscribe to changes and events.

This allows, for example:

• Another application can 'listen' for changes to a facility list and import facility data when a new facility is added, or update its information when a facility gets updated or deleted.
• A service-oriented architecture environment can trigger business processes and other services based on a facility opening, or closing
• A data collection tool can listen for changes in layers and definitions of forms, to update its internal form definitions
• Someone can create an alert so that when permissions change for a collection, they can go and review how they have changed to make sure only authorized folks have the right sort of access
• An application can show a nice 'Audit Log' of who has done what
• You could customize alerts and actions to happen based on general tools that subscribe to RSS feeds such as If-This-Then-That (http://ifttt.com/)

In order to do this, an application can subscribe to the activity RSS feed.

The RSS feed is accessible here:

http://resmap-stg.instedd.org/api/activity.rss

There is also a user interface you can browse here

Security

The activity will be filtered by the collections, layers, sites etc. that the current user has access to. The feed is authenticated with HTTP Basic authentication.

Filtering

The activity feed supports parameters for filtering it across action/verbs and collections. Further filtering and refinement has to be done by clients.

To filter for a collection:

http://resmap-stg.instedd.org/api/activity.rss?collection_ids%5B%5D=777

To filter by a type of change:

http://resmap-stg.instedd.org/api/activity.rss?&collection_ids%5B%5D=777&kinds%5B%5D=site%2Ccreated

The following kinds of verbs can be filtered for:

• Collection created
• Collection imported
• Collection CSV imported
• Site created
• Site changed
• Site deleted
• Layer created
• Layer changed
• Layer deleted
