The International Hydrographic Organization (IHO) S-100 data model is the baseline for the Common Maritime Data Structure (CMDS), which defines what data should be exchanged in e-Navigation (MSC 90/28, paragraph 10.10).
The S-100WG was stood up to take a leadership role in the creation, implementation and oversight of the introduction of S-100 based services in Australia by developing documentation, creating national guidelines and policies, defining roles, responsibilities and controls that will harmonize the Australian e-Navigation data chain.

The results of the SIDA survey conducted in 2014 are now available.

The SIDA group was disbanded in October 2015.
