Custom cross-references should not be used in ISO standards, either for an external reference, or for a section of the current document: ISO/IEC DIR 2 requires any cross-references to be transparent in text.
For example, a cross-reference to the anchor such as:
on clause 5 should be given as just:
…and custom text will be automatically rendered as
Clause 5 by Metanorma-ISO.
ISO clause references will suppress the word "Clause" before a subclause reference,
following ISO/IEC DIR 2:
< will be rendered as ISO 24333, Clause 5,
< will be rendered as ISO 7301, 3.1.
|This subsection supplements References & Bibliography in general Metanorma documentation.|
All references under Normative References are expected to have such a standard document identifier. For example:
* [[[ricepotentialmilling,ISO 6646]]], _Rice -- Determination of the potential milling yield from paddy and from husked rice_ * [[[ISOGuide73, ISO Guide 73:2009]]], _Risk management -- Vocabulary_
ISO 6646 in this example would be cited from elsewhere in the document through cross-references to the
ricepotentialmilling identifier; e.g.
<< ricepotentialmilling>> (which will be rendered as
<< (which will be rendered as
ricepotentialmilling, section 5>>
ISO 6646, Section 5),
<< (which will be tagged in the XML representation as Section 5 of ISO 6646, but will be displayed as
ricepotentialmilling,section 5: the foregoing discussion>>
the foregoing discussion.)
ISO treats dated and undated references as separate (an undated reference is taken to refer to the latest published edition of that reference.) if reference is to be made to both an undated and a dated version of an ISO reference, these need to be explicitly listed as separate references.
If an ISO reference is in preparation, ISO/IEC DIR 2 dictates that details of the reference status be given as a footnote. In Asciidoc, this is done by giving the date as a double dash, and following the bibliographic anchor with a footnote macro:
If an ISO reference includes all parts of the standard, that is indicated by appending
In informative references, references to standards documents are still given with the same format of bibliographic anchor, and they are cited by their document identifier — although they are displayed with an incrementing reference number in brackets, for consistency with any bibliographic entries that are not standards documents. ISO references appear before non-ISO references. So
[bibliography] == Bibliography * [[[ISO3696,ISO 3696]]], _Water for analytical laboratory use -- Specification and test methods_ ... * [[[ref11,11]]] Nitrogen-ammonia-protein modified Kjeldahl method -- Titanium oxide and copper sulfate catalyst. _Official Methods and Recommended Practices of the AOCS_ (ed. Firestone, D.E.), AOCS Official Method Ba Ai 4-91, 1997, AOCS Press, Champaign, IL
is displayed as:
 ISO 3696, Water for analytical laboratory use — Specification and test methods …  Nitrogen-ammonia-protein modified Kjeldahl method — Titanium oxide and copper sulfate catalyst. Official Methods and Recommended Practices of the AOCS (ed. Firestone, D.E.), AOCS Official Method Ba Ai 4-91, 1997, AOCS Press, Champaign, IL
The entries in the Bibliography are reordered (and, for numerical references, renumbered) according to the following criteria:
Document class (as defined in the ISO sample Rice document): standard which ISO has published or co-published; standard which IEC has published or co-published; other standards; other documents.
Standards are identified by the use of a code for the document identifier, as opposed to a number.
Document identifier type (as a proxy for the standards setting body)
Document number (the numeric portion of the standards identifier, sorted numerically)
Full document identifier
The bracketed reference numbers are expected to be correct and in order (accounting for the fact that references to standards will end up numbered): they are not overriden in rendering.
Annexes & appendices
In ISO, Appendixes to annexes can occur, although they are not mentioned in ISO/IEC DIR 2; ISO/IEC DIR 1 features them. They are marked up as immediate subsections of annexes, and must be tagged with an option attribute of "appendix":
[appendix] == Annex A Text [%appendix] === Appendix 1 Text
Additional warning types
Metanorma AsciiDoc natively supports the ISO admonitions “Caution”, “Warning”, and “Important” through its admonition syntax:
CAUTION: This is a single-block caution [WARNING] ==== This is a multiple-block warning ====
If the admonitions "Danger" and "Safety Precaution" are needed, they should be indicated
type attribute, which will override the admonition type appearing in the AsciiDoc:
[type=Danger] CAUTION: This is a single-block caution [WARNING,type=Safety Precaution] ==== This is a multiple-block warning ====
Terms and Definitions
|This subsection supplements Terms and definitions in general Metanorma documentation.|
The title of a top-level Terms and Definitions clause is populated automatically, overriding the title provided by the user: if it contains a Symbols and Abbreviated Terms subclause, it is titled Terms, definitions, symbols and abbreviated terms, otherwise it is titled Terms and definitions.
Symbols and Abbreviated Terms subclauses are also automatically titled; other subclauses of Terms and Definitions clauses are not.
Unordered lists in Word are rendered with em-dashes instead of bullets, as preferred by ISO.
