Importing metadata when creating epub

[photoluminations]

I am building an original epub book from html + css files. I wish to enter the metadata from a text file. I can't download from the usual places which describe already-published books. Is there a way to import the metadata?

Since I am developing the format as well as the content, I need to generate new epub copies frequently, and would like to import the metadata by calling it from a file.

I recognize that I can open the epub after it is generated by calibre and include a file with the metata, then re-zip. Is there another way?

Put your metadata in the html

OK, that was a helpful lead. But I'm having problems implementing.

I enter the metadata in the head part of the html file, but I am missing how to code this properly.

If I enter the package and metadata declarations, it seems NOT to accept closing tags. Some of the metadata flows through and can be read by Adobe Digital Reader (ADR), but unless I enter the publisher in the "edit metadata" section of calibre, ADR says publisher unknown.

If I just enter the metadata details in the head of the html file, the first page of the calibre epub output lists the metadata.

My goal remains to create a metadata entry that does not require tweaking in calibre or after generating the epub. Kindly point out where I have gone astray. Thanks.

From the head section of the html:

<?xml version="1.0" encoding="UTF-8" ?>
<package version="2.0" unique-identifier="PrimaryID" xmlns="http://www.idpf.org/2007/opf">
<metadata xmlns:dc="http://purl.org/dc/elements/1.1/"
xmlnspf="http://www.idpf.org/2007/opf">
