Part 12 - S-100 Maintenance Procedures
S-100 Edition 2.0.0
12-1
June 2015
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
manager 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
Change proposals for S-100 are coordinated by S-100WG and shall be made available via
the IHO web site. Organizations that wish to make changes to S-100 must address their
change proposals to the International Hydrographic Bureau.
Changes to S-100 are classified at one of three different levels: new edition, revision, or
clarification. In each case, the development, consultation and approval process will be slightly
different, ranging from a very comprehensive regime for new editions, to approval at the level
of a subordinate body for clarifications. New editions and revisions are considered to be
“significant changes” for the purposes of review, consultation and approval.
All proposed changes shall be technically and commercially assessed before approval. All
proposals shall be submitted to the secretary S-100WG using the S-100 Maintenance Change Proposal Form in Appendix 12-A (normative).
Changes to IHO technical standard S-100 shall be subject to the terms of Resolution 2/2007.
12-2.1
Clarification
Clarifications are non-substantive changes to S-100. Typically, clarifications: remove
ambiguity; correct grammatical and spelling errors; amend or update cross references; insert
improved graphics in spelling, punctuation and grammar. A clarification must not cause any
substantive semantic change to S-100. Clarifications are the responsibility of the relevant
subordinate body and may be delegated to the responsible editor.
12-2.2
Revision
Revisions are defined as substantive semantic changes to S-100. Typically, revisions change
existing specifications to correct factual errors; introduce necessary changes that have
become evident as a result of practical experience or changing circumstances; or add new
specifications within an existing section. Revisions could have an impact on either existing
users or future users of a revised standard. It follows that a full consultative process that
provides an opportunity for input from as many stakeholders as possible is required.
Proposed changes to S-100 should be evaluated and tested wherever practicable. The
approval of Member States is required before any revisions to S-100 can enter into force. All
cumulative clarifications must be included with the release of approved corrections revisions.
A revision shall not be classified as a clarification in order to bypass the appropriate
consultation processes.
12-2.3
New Edition
New Editions of S-100 introduce significant changes. New Editions enable new concepts,
such as the ability to support new functions or applications, or the introduction of new
constructs or data types, to be introduced. New Editions are likely to have a significant impact
on either existing users or future users of the revised standard. It follows that a full
consultative process that provides an opportunity for input from as many stakeholders as
possible is required. Proposed changes to S-100 should be evaluated and tested wherever
practicable. The approval of Member States is required before any New Edition of S-100 can
enter into force. All cumulative clarifications and revisions must be included with the release
of an approved New Edition of S-100.

Identifiers
Change Proposal
In this section is strongly recommended the specification of “persistent global
identifier” for features and information objects; however it is also mentioned that
some objects/conditions do not need identifiers. In our opinion, the data product
specification shall define exactly what those objects/conditions are. Furthermore, the
data product specification shall define objectively the rules to construct the
“namespaces”.
Change Proposal Justification
In order to avoid ambiguities
Please send completed forms and supporting documentation to the International
Hydrographic Bureau (addt@iho.int).
