Updates to the OPF specifikation.

[kalaspuffar]

Hi @josteinaj

Changes made:

• [opf3a] Removed
• [opf3c]: 3-letter codes should also be allowed, use same regex as in #82 [nordic131]
• [nordic131] Changed it to use the same regex.
• [opf3f]: Removed, unnecessarily strict (not required in the guidelines).
• [opf3h][2]: Removed, as publications might not always have an ISBN or ISSN (see #116)
• [opf3h][3]: Made applicable only when urn:isbn: or urn:issn: is present -* [opf5a]: Removed
• [opf6]: Applies only if ncx is present, only updated to it needed to reference the nav.ncx document.
• [opf12b_type]: Updated to allow ARIA DPUB roles and disallow Z39.98-2012 values.

Best regards Daniel

Seemed that I did a lot of whitespace changes without meaning to. Do you want me to change that or should we use the GitHub feature for whitespace?

[josteinaj]

It looks like the entire nordic2020-1.sch file has been changed unless I enable the whitespace option. If its not too much trouble, it would be nice if you could revert the lines that wasn't really changed.

Hi @josteinaj

I've also removed the auto line endings in git to allow the Windows line endings the nordic2020-1.sch file uses.

Hi @josteinaj

Added rules to handle

• if there is a spine item with the role "titlepage" or "halftitlepage", then any spine items preceding the first of those should have linear="no". (if there's both a titlepage preceding the halftitlepage, then only require this for spine items preceding the titlepage - and vice versa) (note that the role can be extracted from the filename)
• any spine items preceding "cover" (there shouldn't be any, but in case there is…) must have linear="no" (handles cases where there is no titlepage/halftitlepage)

Best regards Daniel

I think the only issue remaining for this PR is that we need feedback from @AndersEkl and/or @martinpub about the maintitle issue.

Hi @josteinaj

Great suggestion, It makes no sense to have multiple main titles. I've changed the logic only to allow one uniquely defined main title or only one title.

@kalaspuffar: The changes looks good now. However: "This branch cannot be rebased due to conflicts: Rebasing the commits of this branch on top of the base branch cannot be performed automatically due to conflicts encountered while reapplying the individual commits from the head branch."

Could you rebase your local opf_updates branch onto nlbdev:guidelines-revision and force-push over kalaspuffar:opf_updates, so that it becomes possible to merge this branch?

Hi @josteinaj

I have now rebased the files.

Best regards Daniel
