Where should I put external web service processing logic in Rails?

Question

In my rails application I use some external web services: twitter, google picasa, flickr etc.

Where should I put code related to processing responses of these services?

Answer 1

You can create abstract models (non-persistent) for each of these so each abstract model can be responsible for processing requests and so forth.

Data structure could look like this:

app/models/web_services/
  google.rb
  twitter.rb
