| | +# Document metadata |
| | + |
| | +Document metadata is information about a document. Metadata often includes |
| | +a title, author name, copyright date, and keywords. |
| | + |
| | +# Custom metadata |
| | + |
| | +The following screenshot shows example metadata preferences: |
| | + |
| | + |
| | + |
| | +The **Key** column lists metadata names and the **Value** column lists |
| | +the metadata content for each corresponding **Key**. The content may |
| | +include references to variable definitions. When the document is typeset, |
| | +the values for the variables will be substituted upon export. |
| | + |
| | +When the document is exported as XHTML, the header will include the |
| | +keys and values conforming to the XHTML specification. For example: |
| | + |
| | +``` html |
| | +<head> |
| | + <title>Document Title</title> |
| | + <meta content="science, nature" name="keywords"/> |
| | + <meta content="Penn Surnom" name="author"/> |
| | + <meta content="4311" name="count"/> |
| | +</head> |
| | +``` |
| | + |
| | +# Special metadata |
| | + |
| | +When exporting the document, note the following special metadata: |
| | + |
| | +* **author** -- Included as PDF metadata |
| | +* **byline** -- Replaces author in PDF metadata (e.g., for pen names) |
| | +* **count** -- Total word count in document, automatically included |
| | +* **keywords** -- Included as PDF metadata |
| | +* **title** -- Included as a `<title>` tag, rather than a `<meta>` tag |
| | + |
