Part 12 - S-100 Maintenance Procedures
S-100 version 1.0.0
12-1
January 2010
Scope
As users begin to implement S-100 and associated product specifications, errors and
deficiencies in S-100 may be found and these will need to be handled in a uniform manner.
This Part specifies procedures to be followed in updating, maintaining and publishing the
various parts of S-100. It excludes the maintenance of the S-100 registry, as each register
owner will have their own specific procedures for updating their register(s). Additionally, this
Part excludes the maintenance regime of product specifications. However, S-100 versions
must be backward compatible to ensure interoperability of product specifications.
NOTE All S-100 based product specifications shall include a maintenance section.
12-2
Maintenance Procedures
Changes to S-100 are coordinated by the "Transfer Standard Maintenance and Application
Development Working Group" (TSMAD) of the IHO and shall be made available via the IHO
web site. Organizations that wish to make changes to S-100, must address their comments
to the International Hydrographic Bureau.
There are three change proposal types to S-100: clarification, correction and extension. Any
change proposal must be one of these types.
All proposed changes shall be technically and commercially assessed before approval. All
proposals shall be submitted using the S-100 maintenance proposal form in Annex A.
Maintenance of S-100 and the release of new versions is governed by the rules laid out in
IHO Technical Resolution A1.21.
12-2.1
Clarification
Clarifications are defined as non-substantive changes to S-100. Clarifications remove
ambiguity and errors in spelling, punctuation and grammar. A clarification shall not cause any
substantive semantic change. A clarification shall not be classified as a correction.
12-2.2
Correction
Corrections are defined as substantive semantic changes to S-100 to correct factual errors. A
correction shall not be classified as a clarification. One correction may result in multiple
related actions. All cumulative clarifications shall be included with the release of approved
corrections.
12-2.3
Extension
Extensions are significant changes to S-100. They can include additional information from
the IHO or ISO TC211 geographic information standards that were not originally included in
S-100 that may be needed for additional applications. Extensions result in a new major
version of S-100. One extension may result in multiple related actions. All cumulative
clarifications and corrections shall be included with the release of approved extensions.
12-3
Version Control
The IHO shall release new versions of S-100 as necessary. New versions shall include
clarifications, corrections and extensions. Each version shall contain a change list that
identifies the changes between versions of S-100.
12-3.1
Clarification Version Control
Clarifications shall be denoted as 0.0.x. Each clarification or set of clarifications approved at
a single point in time shall increment x by 1.
12-3.2
Correction Version Control
Corrections shall be denoted as 0.x.0. Each correction or set of corrections approved at a
single point in time shall increment x by 1. Correction version control shall set clarification
