There is a lot of talk about metadata in digital formatting, but occasionally, when creating various formats, the tools one uses has no way to insert the metadata. (Aside: In my experience with various ebook creation tools, Sigil, thus far, has the most complete, complex, and wonderful feature for inserting metadata.)
However, there is a way to do it manually in the XHTML file used to plug into the creation tools. Quite frankly, I’m not sure it translates to any particular e-reading software or devices, but it does leave a record, and recordkeeping is the whole point of metadata.
This is my header:
<!DOCTYPE html PUBLIC “-//W3C//DTD XHTML 1.1 Transitional//EN” “http://www.w3.org/TR/xhtml1/DTD/ xhtml1-transitional.dtd”>
<meta http-equiv=“Content-Type” content=“application/xhtml+xml; charset=utf-8” />
<meta name=“author” content=“AUTHOR NAME” />
<meta name=“title” content=“TITLE” />
<meta name=“copyright” content=“YEAR, AUTHOR” />
<meta name=“description” content=“CATEGORY” “BISAC CODE” />
<meta name=“ISBN” content=“ISBN-13: 978-XXX” “ISBN-13: 0-XXX” />
<meta name=“formatter” content=“B10 Mediaworx” “http://b10mediaworx.com” />
<title>TITLE by Author</title>
[insert other normal header stuff]
You can add categories at will, and you should.
Going forth into the digital frontier, such information will be crucial, even if any given software or device can’t read it.
