<h3>Several issues with the current formatter options</h3>
<h4>Translatability</h4>
<p>With the generic translatable strings <code>{{ 'by'|trans }}</code>, <code>{{ 'at'|trans }}</code>, <code>{{ 'as'|trans }}</code> it's close to impossible to nail a suitable translation for attributions without side-effects. </p>
<p>Even more when people do not 100% understand what's expected or use the fields freehand to solve their current need.</p>
<h4 id="theming">Theming requirements</h4>
<p>Although there are already 6 formatters, none serves the typical theme's requirements: </p>
<ul>
<li>Move attribution onto the lower left part of an image</li>
<li>Provide a toggle and show the attribution text in a popover element (cf. OpenCulturas)</li>
</ul>
<h4 id="style">Separate style from content</h4>
<p>Apart from the icons style there is currently no formatter to display the <em>Identifier</em> ("short name") instead of the long <em>Name</em>.</p>
<p>There is currently no option to use the official CC icon images (2 versions available).</p>
<p>There is currently no option to simply set a separator instead of words (see translatability).</p>

<h4 id="challenges">The challenges</h4>
<ul>
<li>All fields could be optional. Sentences should have a consistent logic in any case</li>
<li>No assumed link markup (only build links when there is a link, e.g. license "All rights reserved")</li>
<li>Keep "one line" formats least verbose</li>
<li>Assume verbose formats to only appear in stand-alone displays (if at all)</li>
<li>Styles should be confineable to particles (e.g. Icons formatter should be styleable to only format the CC licenses short names)</li>
<li>Translations should be context-sensitive (see issue body)</li>
</ul>
<h3 id="resolution">Proposed resolution</h3>
<p>Build one final formatter <em>with settings</em>: <strong>Attribution options</strong>:</p>
<ul>
<li>Provide translatable strings like <code>by <a href=":author_url">@author</a></code>.</li>
<li>Provide detection of license machine name starting with <code>cc</code> (not cc-dash) and provide version-agnostic icon names</li>
<li>Formatter settings toggle: "Use field label as popover toggle" (default off)</li>
<li>Formatter settings toggle: "Use dividers instead of sentences" (default off)</li>
<li>Formatter settings toggle: "Use license identifier instead of name" (default off)</li>
<li>Formatter settings toggle: Replace Creative Commons name/identifier with icon (default off)</li>
<li>Formatter settings toggle: Replace AI type with icon (default off)</li>
<li><del>Formatter settings toggle: Show source (default on)</del></li>
</ul>
