<ul class="remarkup-list">
<li class="remarkup-list-item">retrieval for searching/caching properties</li>
<li class="remarkup-list-item">on-demand extraction</li>
</ul>
<p>Baloo falls into the first category. It is only interested in properties which can be queried/compared in a<br />
meaningful way. Even storing the properties as a cache for e.g. Dolphin is a little bit of a stretch.</p>
<p>Elisa falls into the second category. It does not store the extracted data persistently, but is fine<br />
extracting e.g. the front cover on demand.</p>
<p>Currently the only large/blob property is the front cover. But what about BackCover, Leaflet pages,<br />
..., Video Thumbnails? Returning all of these even when not required is wasteful. If you want a<br />
front cover, say so.</p>
<p>For KF6, ExtractEverything should just be removed. It is not especially useful, not even for unit tests.<br />
Request the data you want and are able to handle, and do so explicitly.</p></div></div><br /><div><strong>INLINE COMMENTS</strong><div><div style="margin: 6px 0 12px 0;"><div style="border: 1px solid #C7CCD9; border-radius: 3px;"><div style="padding: 0; background: #F7F7F7; border-color: #e3e4e8; border-style: solid; border-width: 0 0 1px 0; margin: 0;"><div style="color: #74777d; background: #eff2f4; padding: 6px 8px; overflow: hidden;"><a style="float: right; text-decoration: none;" href="https://phabricator.kde.org/D25517#inline-148827">View Inline</a><span style="color: #4b4d51; font-weight: bold;">extractionresult.h:62</span></div>
