RE: [dpub identifiers] Please review updated Identifiers TF wiki

Precisely! Thanks.

When people respond by saying, wrt pointing just to the start of the print page on which the thing you really mean occurs (the thing the index entry means, the thing the cross reference is referencing, etc.), "what the heck good is that?", I point out that that is precisely all that those things have ever done in print. ☺ They just say "somewhere between this point, where page 53 begins, and the next such milestone marker, which says where page 54 begins . . . somewhere between those two markers is the thing I'm trying to direct your attention to." So using them is regrettably no better, but at least no worse, than what they've always done.

My apologies if this has been asked before, but is there a generic "milestone" type ID?  Ultimately that's what a page-number is.  The same way a section heading, or chapter is a chunk identifier, a page is ALSO a chunk identifier.  The fact that the context is related to a concept foreign to screens (or at least, difficult to understand when it comes to screens) if you think of it as a "physical_page_number" as opposed to just "page_number" the conceptual chunk because significantly clearer and more meaningful.

If this doesn't make sense, let me know and I'll try to word it elsewise.

In EPUB3 files, HTML content is tagged with empty anchors like :
"Ils n¹en veulent pas, ils n¹en <a id="page_182"/>veulent pas, elle lâche
dans un soupir en attrapant encore une lettre."

This means that a new paper page starts at word « veulent ».

In parallel, the EPUB3 nav document contains an ordered list of navigation
points in a <nav epub:type="page-list »> element :
<li>
   <a href="chap22.html#page_182">Page 182</a>
               </li>
Then the label of this paper page 182 is « Page 182 ».


In term of worflow, by good practice, we produced a new EPUB file as soon
as text corrections have been inserted in the reprint book.


In EPUB3, there's metadata that should indicate which print edition the pagination information is taken from [1]:


<dc:source id="src-id">urn:isbn:9780375704024</dc:source>

    <meta refines="#src-id" property="identifier-type" scheme="onix:codelist5">15</meta>
<meta refines="#src-id" property="source-of">pagination</meta>
