How SDP is built and connects together

SDP offers three product layers that can be used independently, or as a package:

  • Ripple is the presentation layer, this is what people see as your website.
  • Tide is the content management layer, built on Drupal 8.
  • Bay is the infrastructure and hosting layer.

SDP is managing its public code repository on GitHub.

The vanilla offering includes all the SDP products, (Bay, Tide and Ripple).

A digital agency is required to build the presentation layer.  

The agency can change the interface style (including logo and colours) but cannot change its function. This means they can change the CSS but not the JavaScript. 

The government agency owns and manages its own content. 


  • is hosted on SDP infrastructure (Bay) 
  • uses the SDP Drupal 8 distribution (Tide) 
  • uses the SDP pattern library (Ripple) 

SDP continually improves, maintains and supports the vanilla offering.  


The custom offering uses the SDP infrastructure (Bay) and distribution (Tide) as the basis for the  

development of the website. The use of Ripple is optional. 

A digital agency is required to build the presentation layer and any custom features in Drupal.  

The government agency owns and manages their own content. 


  • is hosted on SDP infrastructure (Bay) 
  • uses the SDP Drupal 8 distribution (Tide) as a base 
  • uses the SDP pattern library (Ripple) as a base (optional) 

SDP will make updates available, although the government agency is responsible for improving, maintaining and supporting their own website. 

SDP - what's not included

SDP is focused on delivering information to Victorian citizens. Features and functions that sit outside of this include: 

  • registrations and payments 
  • intranets 
  • back- end business functions
