[GUI Plugin] ePub Extended Metadata

[un_pogaz]

ePub Extended Metadata is a plugin whose objective is to allow to read and write a wider range of ePub metadata according to the ePub standard.

• Read and write contributors <dc:contributor> in columns (type names)

Once the different metadata is set, you will be able to import or embed its advanced metadata in your ePub in one click.

It is also possible to activate the automatic import/reading of its metadata when adding a book to your library.
Also, it is possible to activate a automatic integration of them at the same time as the default Calibre Embed action, without having to specifically activate.
Of course, other metadata not set in your plugin are kept.

Note:

1. the setting of "ePub Extended Metadata" is done by Library.
2. "ePub Extended Metadata" came with 2 companion plugin "ePub Extended Metadata {Reader}" and "ePub Extended Metadata {Writer}" that are auto-installed, so do not be surprised to see them appear, it means the plugin has been properly installed.

Credits:

• The MARC Code associated name and decriptions are extracted from the Sigil code source (with minor edit)
• Some translation of the MARC Code are also based on the translation made for Sigil (language: FR)

Installation
Open Preferences -> Plugins -> Get new plugins and install the "ePub Extended Metadata" plugin.
You may also download the attached zip file and install the plugin manually, then restart calibre as described in the Introduction to plugins thread

The plugin works for Calibre 5 and later.

Note for those who wish to provide a translation:
I am French! Although for obvious reasons, the default language of the plugin is English, keep in mind that already a translation.

Is this open source? Is there a public repository? (It has potential for something I'd like to see, and I'd contribute code back if it worked...)

[un_pogaz]

Yep GitHub here
It would be a pleasure.
Thanks.

In ePub2, I don't seem to have missed anything. If so I would take courage to do so.
But the specific ePub3... one day but not today for me.

[jktrigg]

Just to be clear, what I want to add is importing metadata from the title page. I have an archive of ~7000 fanfics from a no longer functioning site. The epubs have no metadata, but the title page has plenty... I want to scan the title page for things like characters, relationships, etc.+

[un_pogaz]

I'm afraid I have to refuse.
The plugin "ePub Extended Metadata" is intended to read ONLY the metadatas defined in the ePub standard, and thus in the OPF. And nowhere else.

I suggest you open a new thread in Calibre>Géneral or Calibre>Library Management, and explaining in detail your situation, with an example of the source file and the information to be extracted (maybe several).
It's probably possible to do this programmatically, with a python script, but this is not the right place to this.

Good luck and have a nice day.

Did you actually read the books these fanfics are based on?
