A combination of the format/medium of a document with one or more events from its lifecycle, for example, “epub” for publication in an electronic format or “ppub” for print publication.
The combination of format and medium in one attribute is a holdover from previous versions of this Tag Set. In this version of this Tag Set, there are two attributes that can be used to describe the history dates and publication dates of articles. The @date-type attribute records the type of event in the lifecycle, such as “accepted”, “published”, or “revised” dates. In addition, the @publication-format attribute records the type of format or media to which the event happened, such as “print”. In previous versions of this Tag Set, the two types of information were combined, so an attribute could say that an article was “ecorrected”, meaning that the article was in electronic form and that it was corrected. In this Tag Set, the attribute @date-type would take the value “corrected” and the @publication-format attribute would take the value “electronic” to convey the same information.
|Text, numbers, or special characters||The type of print or electronic publication, for example, “epub” for electronic publication.|
Historical Note: In this version of this Tag Set, the @publication-format attribute states the format/medium and the @date-type attribute names the lifecycle event. For previous versions of this Tag Set, the information on type of lifecycle date and format/media to which the event happened were combined in this attribute. A content creator may choose to keep this information combined, even in this Tag Set, and use the following values (which blend the type and format and are therefore no longer recommended) for this attribute:
Electronic publication (usually web, but also includes eBook, CD-ROM, or other electronic-only distribution)
Both print and electronic publications
Electronic preprint dissemination
Print preprint dissemination
Corrected in electronic
Corrected in print
Retracted in electronic
Retracted in print
