Author Information

Adding author information to your document is optional. A document’s author information is assigned to multiple built-in attributes. These optional attributes can be set and assigned values using the author line or using attribute entries in a document’s header.

Author and email attributes

author: The author attribute represents the author’s full name. The attributes firstname, middlename, lastname, and authorinitials are automatically derived from the value of the author attribute. When assigned implicitly via the author line, the value includes all of the characters and words prior to the semicolon (;), angle bracket (<), or the end of the line. Note that when using the implicit author line, the full name can have a maximum of three space-separated names. If it has more, then the full name is assigned to the firstname attribute. You can adjoin names using an underscore (_) character.
email: The email attribute represents an email address or URL associated with the first author (author). When assigned via the author line, it’s enclosed in a pair of angle brackets (< >).

Name and initials attributes

firstname: The firstname attribute represents the first, forename, or given name of the author. The first space-separated name in the value of the author attribute is automatically assigned to firstname.
lastname: The lastname attribute represents the last, surname, or family name of the author. If author contains more than one space-separated name, the third name and any names after that are assigned to the lastname attribute.
middlename: The lastname attribute represents the middle name or initial of the author. If author contains more than two space-separated names, the second name is assigned to the middlename attribute.
authorinitials: The first character of the firstname, middlename, and lastname attribute values are assigned to the authorinitials attribute. The value of the authorinitials attribute will consist of three characters or less depending on how many parts are in the author’s name.

Multiple author attributes

author_<n>: An author_<n> attribute represents each additional author’s full name, where <n> is the 1-based index of all of the authors listed on the author line (e.g., author_2, author_3). The attributes firstname_<n>, middlename_<n>, lastname_<n>, and authorinitials_<n> are automatically derived from author_<n>. Additional authors can only be assigned via the author line. Each author’s full name includes all of the characters and words directly after a semicolon (;) but prior to the angle bracket (<), next semicolon (;), or the end of the line. The full name can have a maximum of three space-separated names. If it has more, then the full name is assigned to the firstname_<n> attribute. You can adjoin names using an underscore (_) character.
email_<n>: The email_<n> attribute represents an email address or URL associated with each additional author (author_<n>). It’s enclosed in a pair of angle brackets (< >) on the author line.
firstname_<n>: The first space-separated name in the value of the author_<n> attribute is automatically assigned to firstname_<n>.
lastname_<n>: If author_<n> contains more than one space-separated name, the third name and any names after that are assigned to the lastname_<n> attribute.
middlename_<n>: If author_<n> contains more than two space-separated names, the second name is assigned to the middlename_<n> attribute.
authorinitials_<n>: The first character of the firstname_<n>, middlename_<n>, and lastname_<n> attribute values. The value of the authorinitials_<n> attribute will consist of three characters or less depending on how many parts are in the author’s name.
