Terms and definitions: Format, Abbreviations

[ERyan71258]

The terms are not numbered. Per ISO, each term must be numbered.

All of the terms are not really terms, but instead expansions of abbreviations that serve as the definitions. They should go instead into an "Abbreviated terms" clause, or be wrapped into the "Terms and definitions" clause, with the change to the clause title to "Terms, definitions, and abbreviated terms".

Note that it is not required to number symbols.

When listing an abbreviation, there is no guidance in ISO document as to whether the term is the expanded version and the definition is the abbreviation, or vice versa. If there is an actual definition, then the expanded version of the term is listed first, then underneath, the abbreviation, all as part of term heading. That is followed by the definition.

As per: SMPTE/st430-1#102 (comment):

We need to figure out a consistent way to format:

• A term with only an abbreviation. This would usually be listed in a separate "Abbreviations" clause or subclause, but can be included in the Terms and Definitions, with the appropriate heading, e.g., "Terms, Definitions, and Abbreviated Terms"
  Perhaps list as follows, all bold:

  Key Delivery Message
  KDM

• A term with only an abbreviation that cites a source.
  I would format as follows, with the term and its abbreviation in bold:

  Coordinated Universal Time
  UTC
  [SOURCE: ISO 8601-1]

Can we combine this with #117?

[ERyan71258]

Yes.
