Author name in "dc:creator" tag ignored

[mikebw]

I am trying to build an EPUB or MOBI book from the RSS feed of Motif Magazine. This should be fairly simple, and it mostly works, but the name of the author is ignored. The web site uses WordPress and has both the standard built-in feed and a custom feed generated by a plug-in:

http://motifri.com/feed (built-in)
http://motifri.com/?call_custom_simple_rss=1 (plug-in)

The web site is freely accessible to the public, so anyone is welcome to use the RSS feeds. I have administrative control over the web server, but want to avoid customization unless necessary. Here's an example "item" from the plug-in RSS feed:

<item>
  <title>No Simple Answers in Counter-Productions’ Gidion’s Knot</title>
  <link>http://motifri.com/no-simple-answers-in-counter-productions-gidions-knot/</link>

I realize that "dc" is an XML namespace -- https://www.ddialliance.org/Specific...-overview.html -- and I assume Calibre should do something with it, but I'm not sure what and I definitely don't know how to make that happen.

I don't even care about a fancy by-line format, although that would be nice; I just want the name of the author to appear in the article.

You want feed metadata to appear in the article? There is no easy way to accomplish that, you would need to override parse_feeds() in your recipe to store a mapping of article url to author name, then implement preprocess_raw_html() in your recipe to use that mapping to insert the author name into the article HTML

When you put it that way, I concluded that the correct solution was to modify the server code in the "feed-rss2.php" file:

        <?php $content = get_the_content_feed('rss2'); ?>
        <?php if ( strlen( $content ) > 0 ) : ?>
                /* Insert author name into content -- 2019-05-28 */
                <?php $content = "<p><b>By " . get_the_author() . "</b></p>" . $content; ?>
                <content:encoded><![CDATA[<?php echo $content; ?>]]></content:encoded>
        <?php else : ?>
                <content:encoded><![CDATA[<?php the_excerpt_rss(); ?>]]></content:encoded>
        <?php endif; ?>

While the author's name is metadata, it really should also be treated as part of the content.
