The S-100 Standard is a framework document that is intended for the development of digital products and services for hydrographic, maritime and GIS communities. It comprises multiple parts that are based on the geospatial standards developed by the International Organization for Standardization, Technical Committee 211 (ISO/TC211).
The latest edition (Edition 4.0.0) of the S-100 Standard can be downloaded here .
The video below provides more information about S-100 and dependant Product Specifications currently under development.
The IHOs S-100 Working Group (responsible for maintaining the Standard) recognizes that the standard must evolve in order to cater for new user community requirements and has developed a planned revision cycle for the Standard. User communities are invited to submit proposals for corrections and/or extensions to the standard, for inclusion in the next planned edition. The S-100 planned publication schedule is provided below. Submissions should be sent to the S-100WG Secretary (addt(at)iho.int) in accordance with S-100 Part 12 - Maintenance Procedures
