An important date in the life of a standard, such as the date it was first published or the date it was reinstated. The attributes @date-type and @std-type should be used to specify what event the date names.


Date Type Attribute: @date-type is used to name events in the publishing cycle of the standards document (not in the lifecycle of the standard). Thus date types include events such as “published”, “editorial-change”, or “stabilized-maintenance”.
Standard Type Attribute: A @std-type attribute is used to name events (standards document types) in the lifecycle of the standard, such as “addenda” (which creates a new product, with a new designation that typically adds to a previous dated designation) or “amendment” (which replaces a previously published dated standard and also adds to a previous dated designation).
The original publication of a standard will carry a @date-type of “published” and a @std-type attribute of “new-standard”:
<release-date date-type="published"
Later corrections, amendments, editions, and alternate language versions for a standard will all carry this same release date naming the original publication; but they will also carry additional <release-date> elements that name the different dates on which they are published and the different types of lifecycle events they represent.
Specific Use Attribute: By design, the <release-date> element does not take an @specific-use attribute. If a date does not fit neatly into the @date-type and @std-type attributes just described, then that date should be tagged as a <meta-date> element.

Best Practice: In the original ISO STS Tag Set, the element <pub-date> was used to record the date on which an international standard was first published. NISO JATS has its own journal-article-based definition and attributes for the element <pub-date>. In order to avoid a conflict for organizations which have both journal articles and standards in a single data store, NISO STS Best Practice is to record the date on which a standard is published (as well as other significant dates) using the element <release-date> instead of the element <pub-date>.
