In a set of books I’m typesetting, there’s a glossary after the last chapter. So I set the metadata accordingly: In content.opf’s <guide> section there’s the line
<reference type="glossary" title="Glossary" href="Text/Glossary.xhtml"/>
and in Nav.xhtml’s Landmarks section there’s the line
<li><a epub:type="glossary" href="../Text/Glossary.xhtml">Glossary</a></li>
But of course, the glossary is also the beginning of the back-matter, so I applied that semantic in Sigil. This changed the content.opf entry to
<reference type="other.backmatter" title="" href="Text/Glossary.xhtml"/>
and the Nav.xhtml entry to
<li><a epub:type="backmatter" href="../Text/Glossary.xhtml">Back Matter</a></li>
erasing the fact that this is also a glossary.
Question: Can a file have multiple semantic tags (
i.e., is Sigil doing the wrong thing?) and if so, what would this look like? Two entries in the Landmarks section?
<li><a epub:type="backmatter" href="../Text/Glossary.xhtml">Back Matter</a></li>
<li><a epub:type="glossary" href="../Text/Glossary.xhtml">Glossary</a></li>
One entry with two types?
<li><a epub:type="backmatter glossary" href="../Text/Glossary.xhtml">Glossary</a></li>
EpubCheck seems to be happy with either, so I guess I’m asking—for programs that care, which is better supported?
