Aristotle Metadata Registry
The Aristotle Metadata Registry is commercial Metadata Registry software based on the ISO/IEC 11179 standard for Metadata Registries. It is influenced by the AIHW METeOR Metadata Registry and the Canadian Institute of Health Information Indicator Bank. Aristotle-MDR is designed to describe data holdings databases and associated structural metadata. The Aristotle Metadata Registry was publicly launched at the 2015 IASSIST Conference in Toronto. In 2016, the founders of the Aristotle Metadata Registry were hired by Data61 (a division of CSIRO) to continue development of the platform.

Commercial support 
Commercial support for the Aristotle Metadata Registry is provided by Aristotle Cloud Services Australia (ACSA), a Canberra-based Australian limited liability company. ACSA was founded by the core members of the Data61 Aristotle Metadata team in November 2017 to provide commercial support to government clients and provides a number security and enterprise features within the Aristotle Cloud product line. Aristotle Cloud Services Australia is a member of both the Data Documentation Initiative and member of the Canberra start-up hub Entry29. Aristotle Cloud Services Australia was one of the major sponsors of the 2019 IASSIST conference.

In 2021, Aristotle Cloud Services Australia was a national finalist in the 59th Australian Export & Investment Awards.

 Health indicator and Performance Indicator types to record population-level health and equality indicators such as those collected by the President's Emergency Plan for AIDS Relief and the World Health Organization

Tabilon 
Tabilon is a data request portal powered by Aristotle that provides a streamlined process for researchers to request data from different organizations and institutions. To use Tabilon, researchers create a data passport, which allows them to browse through the platform's metadata and select the data they need for their research. The data request is then sent to a data custodian for approval, who is responsible for managing the data on the platform and ensuring that it is shared and used in accordance with relevant regulations and policies. Tabilon enforces strict privacy policies to protect the personal information of researchers and data custodians, and ensures that data is encrypted and stored securely.
