HTML Metadata

[drsassafras]

I am trying to convert HTML into books.

I would like to know how all the metadata gets automatically imported.

I was directed here: https://www.mobileread.com/forums/sho...44&postcount=9

It lists what metadata is supported, but it seems uncompleted & does not explicitly state what calibre field it imports too. For example, is the Tags filed here?

I am specifically wondering what HTML tags would end up specifying:
1. Cover Image
2. Custom Meta Data
3. Tag Data

Thanks

Brendan

If you want complete metadata control, use an OPF file that references your html file and or use the ebook-meta tool to set metadata after the conversion

I've lost track of all the improvements. Is the opf file linked up to custom metadata yet (i.e., does custom metadata get saved and retrieved from it)?

[kovidgoyal]

No, Charles and I are working on that right now.

Y'all simply amaze me. I keep finding new features I didn't know Calibre had, and then I keep reading this thread and finding out what you're planning to make it even better. Some of it I'll freely admit is over my head, but I'm still lost in wonder and awe.

I really like the OPF idea. When I am creating the OPF, would I only need to create the <metadata> portion or would I also need to generate the <manifest> section?

When you say I would reference it, how would I do this? Through a HTML meta tag? Or do you mean that the OPF be dragged into calabre for processing & the HTML index page be referenced for calabre to link up to the HTML data?

I pulled the OPF metadata off one book I am trying to "bind".

Also, I don't see the cover file referenced here. It is specified in titlepage.xhtml though. Can I specify a cover image in teh OPF? Can you give an example?

I am trying to turn a book archive website that hosts books in HTML over so an ePUB can be made of all of them. I am thinking the most streamlined way i can think of is to have a separate "book" made by the server and zipped up. The zip could the be dragged into calabre, or perhaps unzipped and the index (or some other file) dragged into calabre and boom! the ePUB is created. No manually specifying meta data or format or such.

Thanks for all your help.

add a html file to calibre, it wil be auto converted into a zip that alsocontains an OPF. Open the zip and look at the opf it will give you an idea of what to do.

You need <metaata> for metadata, a <manifest> to list the html files and a <spine> to specify their order.

[drsassafras]

So what you are saying then, is that its not practile to generate a OPF via Server Side script as one WOULD need to specify <manifest> etc. which the script would not nessacaraly know about.

In other words, its not possible to reference a OPF with primarily metadata content to be included in the process of creating a epub from HTML.

Is this what you are saying?

[kovidgoyal]

No, that's not what I'm saying. I'm saying generate the OPF file in your script. there's nothing mysterious about a <manifest>

[Coleccionista]

Would that add support for the dc:language tag in the "Edit metadata" form?

So far it looks that calibre does not retrieve this tag nor does allow to set it.

I have added this tag to all my books so I'd love if it becomes actually useful

[kovidgoyal]

No calibre sets language based on whatever the interface language is. Support for book specific languages is on the todo list
