The DSP Architecture Reference Group (DARG) meeting was held via Webinar on 29 March 2022.

The agenda is available in the table below.

At this meeting, discussion points were:

DARG Charter

The DARG Charter has been updated following the recent DARG membership refresh – there were no major changes.

XBRL to XML – Mapping and cross-form rules

The ATO will review internal processes with a view to reconvene with PLS developers to discuss the way forward for a single source of truth and internally consistent documentation.

Sharing Economy

This program of work is currently on pause. Consultation will resume once the legislation has been announced.

Bulk Data Exchange (BDE)

The Visibility of Super measure is now live and commenced a one-month hyper care period on 1 April 2022.

An overview of the KiwiSaver measure was provided.

Delivery insights and future program

A number of key projects (including Data Visibility expansion of data sets and Activity Statement enhancements) are looking to resume in the second half of 2022, subject to business decisions.

DSPs were asked to provide the ATO with priority data sets and what they hope to see in the next iterations of the Data Visibility project.

API collaboration space

The ATO is considering setting up a new API collaboration space to complement the Digital Services Gateway (DSG) API Portal where the ATO and DSPs can work together to better develop fit-for-purpose services.

API Portal

The API Portal is ready for testing. DSPs were asked to provide the ATO with items that could be potential candidates for the next round of priority services being developed in the API Portal.

SSId and Scopes via OAuth2

OAuth2 will uplift the requirements and address the risks raised with the current Cloud Authentication and Authorisation (CAA) model when applied to DSG.

An impact to DSPs has been identified: Access tokens cannot be re-used for multiple subscribers. New tokens will need to be generated for each business and have a 30-minute expiry window.

DSPs were asked to provide feedback on the proposed technical design of OAuth2.

Your Future Your Super API update

A demonstration on the format and technical details of the Stapled super fund API was provided.

Group discussion & other business

A history of the AS4 implementation and its subsequent consumption of capabilities was provided and a follow-up item has been marked for the next DARG meeting agenda.

The Business Inbox working group is still open. DSPs who are interested in joining can do so by raising a ticket in Online services for DSPs or contacting Sonia Lark directly.

The next DARG meeting is tentatively booked for 26 July 2022 in Melbourne, subject to any restrictions in the state or on-site.

Key outcomes and presentations are available in Online services for DSPs.
