[Q] How to properly include a subtitle?
Yesterday I saw an excellent explanation on how to use subtitles in combination with Kobo e-readers. I knew it was possible, but somehow never implemented it. I decided to bite the bullet and give it a go.
Thereafter, I was figuring: how to add those subtitles actually INSIDE the e-books so they exist outside calibre too (without adding them to the<title>)? There is no defined tag <subtitle> or is there? In short: What might be a proper way to do it? I have seen some constructs in the .opf files like: Code:
<metadata> <meta name="calibre:title_sort" content="Sherlock Holmes"/> </metadata> Code:
<metadata> <meta name="calibre:title_sub" content="The Complete Novels"/> </metadata> |

IIRC epub3 metadata has support for subtitles, though I dont recall the details offhand.

Yes, I found it:
Code:
Name: title-type Description: The title-type property indicates the form or nature of a title. When the title-type value is drawn from a code list or other formal enumeration, EPUB creators SHOULD attach a scheme attribute to identify its source. When a scheme is not specified, reading systems SHOULD recognize the following title type values: main, subtitle, short, collection, edition and expanded. Allowed value(s): xsd:string Cardinality: zero or one Extends: dc:title Code:
<meta refines="#ID12345" property="prism:contentType">article</meta> <meta property="dc:title" id="t4main"> Meet The Rejuvenated, Revitalized LeBron </meta> <meta refines="#t4main" property="title-type">main</meta> <meta property="dc:title" id="t4sub"> After a tumultuous first year in Miami, LeBron James locked himself in his house, rued disappointing his teammates—then worked hard to hone his game. The result: one of the best seasons in NBA history </meta> <meta refines="#t4sub" property="title-type">subtitle</meta> <meta refines="#ID12345" property="dc:creator">LEE JENKINS</meta> |

Adding non-standard metadata into the ePub would not be all that useful, IMHO. calibre already stuffs that into one of it's metadata content block. |

Wife does like the subtitle on "My Books" list on Kobo now that I've started putting a piece of the Blurb or other description in it even if there is no subtitle. Obviously because a title can be in any number of collections no collection is shown there, so the subtitle can give a clue to genre and flavour etc when viewing unread Titles sorted by Recent. Though if a book is in a Series that's a good clue. Sometimes we deviate from original official series name if that's too generic. |

Further, I did found about 78 EPUB3-ish books in my collection, of which only 2 did use the subtitle element. One in the .opf file as follows: Code:
<metadata ...> <dc:title id="maintitle">The Title</dc:title> <dc:title id="subtitle">An Interesting Subtitle</dc:title> . . . <meta property="title-type" refines="#maintitle">main</meta> <meta property="display-seq" refines="#maintitle">1</meta> <meta property="title-type" refines="#subtitle">subtitle</meta> <meta property="display-seq" refines="#subtitle">2</meta> . . . </metadata> Code:
<div epub:type="fulltitle"> <h1 class="BookTitle" epub:type="title" lang="en">Main Title</h1> <h2 class="BookSubTitle" epub:type="subtitle" lang="en" role="doc-subtitle">An Interesting Subtitle</h2> </div> |
