I have no clue on how to do it in bulk.
Probably the same broken way the removed the <guide> and entries.
<guide> is the semantics set in the editor for specific files.
Commonly used entries look like these (file paths will vary)
Code:
<guide>
<reference href="Text/TOC.html" title="Table Of Contents" type="toc"/>
<reference href="Text/p01.html" title="Text" type="text"/>
<reference href="Text/copy.html" title="Copyright Page" type="copyright-page"/>
<reference href="Text/after.html" title="Notes" type="notes"/>
<reference href="Text/titlepage.xhtml" title="Cover" type="cover"/>
</guide>
As you can see/ there is no OSFA set of entries
