What metadata does Calibre support for (X)HTML input? Is there a setting somewhere? I couldn't find anything in the User Manual, but I may have missed it. My experiment with importing XHTML wasn't too effective.
It seems to be able to output such data well, though.
We're having a discussion of Sigil's support for Dublin Core metadata in the <head>
of (X)HTML docs used as input sources here.
Near the bottom is a list of possible DCTERMS that cover most useful metadata as they relate to book collections, and some outliers. There is a specific list of what Sigil currently supports here.
Zipped, single-file XHTML is my storage format of choice, as it should convert easily to pretty much anything. I also edit a lot of files into decently marked-up XHTML. It'd be nice to have Calibre recognize the info.
