No,
I broke it. A real brain-dead "thinko" on my part. Internally metadata changed from not being dc: prefixed to always being dc: prefixed throughout. I made the mistake of carrying that change into the html based metadata code as well. So it is looking for dc:before the name in the meta which makes no sense given it starts with "DC."
So the following will load the metadata from the Open html but that won't do you much good now.
Code:
<meta name="DC.DC:Title" content="The Title"/>
<meta name="DC.DC:Language" content="en"/>
<meta name="DC.DC:Creator" content=""/>
<meta name="DC.DC:Publisher" content="Publisher Name"/>
<meta name="DC.DC:Date" content="2016-03-01"/>
<meta name="DC.DC:Identifier" content="978-0-00000-000-0" scheme="ISBN"/>
<meta name="DC.DC:Relation" content="978-0-00000-000-0" scheme="ISBN"/>
Sorry about that. I will definitely fix this in the next release. The only workaround is to pre-edit the html page in any text editor and replace "DC." with "DC.DC:" inside the html meta tag then it will import properly.
Thanks for your bug report!

Edit: Yes ... please file an official issue on github so I don't forget it. You can simply link to this thread in MR in it if that is simpler.
