<ul class="remarkup-list">
<li class="remarkup-list-item">retrieval for searching/caching properties</li>
<li class="remarkup-list-item">on-demand extraction
<br /><br />
Baloo falls into the first category. It is only interested in properties which can be queried/compared in a meaningful way. Even storing the properties as a cache for e.g. Dolphin is a little bit of a stretch.
<br /><br />
Elisa falls into the second category. It does not store the extracted data persistently, but is fine extracting e.g. the front cover on demand.
<br /><br />
Currently the only large/blob property is the front cover. But what about BackCover, Leaflet pages, ..., Video Thumbnails? Returning all of these even when not required is wasteful. If you want a front cover, say so.</li>
</ul></div>

<p>Yeah, in that case it would be a little bit wasteful. But again, I think if we implement this fine-grained control, it should be done for all properties.<br />
And this is out-of-scope for this patch.</p>

Request the data you want and are able to handle, and do so explicitly.</p></blockquote>
<p>I have adjusted this as requested.</p></div></div><br /><div><strong>REPOSITORY</strong><div><div>R286 KFileMetaData</div></div></div><br /><div><strong>REVISION DETAIL</strong><div><a href="https://phabricator.kde.org/D25517">https://phabricator.kde.org/D25517</a></div></div><br /><div><strong>To: </strong>astippich, Baloo, bruns, mgallien, ngraham<br /><strong>Cc: </strong>kde-frameworks-devel, hurikhan77, lots0logs, LeGast00n, fbampaloukas, GB_2, domson, ashaposhnikov, michaelh, astippich, spoorun, ngraham, bruns, abrahams<br /></div>
