How SDP is built and connects together

Diagram to represent the modules and structure of the SDP platform: our Ripple design system, our Tide Drupal 8 content management system and our Bay hosting environment; comprising site sections on, semi-independent sites with their own URL and fully independent sites.

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.

SDP options


The online entry point to the Victorian Government,, attracts more than 400,000 users per month. It provides an existing platform and established audience for your digital content, with no cost to add content. 

Why use

Audience can find your information  

  • Access to an established audience 
  • Speed to market 
  • Search engine optimisation 

No change to content ownership  

Content owners are responsible for: 

  • Updating content 
  • Following the content standards  
  • Responding to enquiries 

Content governance model ensures standards are met prior to publishing.

Easy to maintain content standards and governance  

  • Training support and best practice advice  
  • A quality assurance check to ensure your content is optimised 
  • Access to analytics and benchmarking content 

Best practice design 

  • Common design pattern that makes it easier for users to navigate, rather than learning a new layout 
  • Design components that are backed by extensive user experience research 
  • Responsive design so your users can easily access information on a phone 

Options on 

  • A flexible campaign template to deliver the digital elements of your campaigns  
  • Departmental initiatives can be delivered within existing sections  
  • Corporate content that relates to your Department as an entity could be delivered – DPC corporate content is now delivered in this way.  

2. Vanilla

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.

3. Custom

The custom offering uses the SDP infrastructure (Bay) and distribution (Tide) as the basis for the development of the website. 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 its own content. 

The custom option:

  • 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 its own website. 

What's not included in SDP

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 
  • integration with other business platforms 
  • data classification above Public Unclassified
