After 11 years of operation, the NSW Registry of Births, Deaths and Marriages will replace its core software system, LifeData, with a new application dubbed LifeLink.

The registry, part of the Attorney General's Department, has released a tender in which suppliers are invited to submit responses outlining "acceptable solutions" including implementation of commercial packages, custom development, or a combination of both.

The high-level requirements of LifeLink must enable the registry to fulfil its mandate of registering the life events of individuals in NSW, enable the linking of life events to produce a person-centric database, produce products like certificates and birth cards, process payments for products, and minimize fraud.

"The new registry system will support the core business services of the registry and all its areas of business," according to the registry. "It includes all the main business and support services of the registry required to fulfil its operational mandate."

The registry's core software processes the registration of births, deaths and marriages in NSW, registration of adoption information, registration of name changes, and registration of sex changes.

This information is kept "in perpetuity" and is provided "in appropriate cases" by government or private agencies and members of the public from within and outside the state.

Tenders close on October 24.
