<h2>What is<br><i>Symmetrical Archiving</i>?</h2>
</section>
<section>
<p>In Web Archiving, archiving and access are typically thought about as two different areas, represented by two software pieces: a <b>crawler</b> and an <b>access system</b>.</p>
<ul style="font-size:80%">
<li class="fragment">Crawlers simulate a subset of the functionality of a real browser.</li>
<li class="fragment">Users expect an archive to reflect how the web looks for a user.</li>
<li class="fragment">No guarantee that crawled material will replay in access system.</li>
<li class="fragment">Feedback on the crawl is delayed until the crawl is finished.</li>
<li class="fragment">Crawlers need lots of technical parameters to retrieve resources that belong to a perceived object.</li>
</ul>
</section>

<h2>An Alternative:<br><i>Symmetrical Archiving</i></h2>
<p>A single, symmetrical system for “recording” and “access”. The user browses in the same way to create the archive and to access it. Same “symmetrical” environment and software stack and code path as much as possible.</p>

<h3>Recordings and<br>“Worm’s Eye Perspective”</h3>
<p>Typically, in Web Archiving we use to think that a web resource is defined by <b>URL</b> and <b>time</b> of access. But that only represents one perspective, and often not a very relevant one. The focus for Webrecorder is preserving the <b>full context</b> visible to a web user.</p>
<p>A typical recording is supposed to be <b>self-contained</b>.</p>
</section>
<section>
<h3>Snapshot</h3>
<p>Current state of the visible DOM (Document Object Model) is stored as a sythetic entry. Depends on the collection to provide referenced items.</p>
</section>
<section>
<h3>Patching</h3>
<p>Only records items that have not been recorded before in the current collection.</p>
</section>
<section>
<h3>Containerized Browsers</h3>
<p>Using remote browsers from a software library for recording and replay at <b>highest possible fidelity</b>; additional automation available.</p>
</section>
<section>
<h3>WARC upload</h3>
<p>Uploaded WARC files are treated as sessions, bookmarks are detected automatically.</p>
