<p>People and the content they create are the core components of the social web; they make up the social graph. This document describes a standard way in which people can:</p>
<ul>
<li>connect with other people and subscribe to their content;</li>
<li>create, update and delete social content;</li>
<li>interact with other peoples' content;</li>
<li>be notified when other people interact with their content;</li>
</ul>
<p>regardless of <em>what that content</em> is or <em>where it is stored</em>.</p>
<p>These components are core building blocks for interoperable social systems.</p>
<p>Each of these components can be implemented independently as needed, or all together in one system, as well as extended to meet domain-specific requirements. Users can store their social data across any number of compliant servers, and use compliant clients hosted elsewhere to interact with their own content and the content of others. Put simply, this document tells you, according the recommendations of the Social Web Working Group:</p>
<ul>
<li>how to <a href="#reading">expose/consume</a> social content (reading).</li>
<li><a href="#content-representation">what to post</a>, and where to, in order to <a href="#publishing">create</a>, <a href="#updating">update</a> or <a href="#deleting">delete</a> content.</li>
<li>how to <a href="#subscribing">ask for notifications</a> about content (subscribing).</li>
<li>how to <a href="#delivery">deliver notifications</a> about content or users (delivery).</li>
<li>how to expose <a href="#profiles">profiles</a> and <a href="#relationships">relationships</a>.</li>
</ul>

<p>This is an overview of the current state of specifications of the Social Web Working Group. This document also describes Social Web Working Group specifications in context of other <abbr title="World Wide Web Consortium">W3C</abbr> recommendations and relevant drafts from other communities outside of the <abbr title="World Wide Web Consortium">W3C</abbr>. As many of these specs are under ongoing development, this document is subject to change alongside them.</p>
<p>You might also want to take a look at the Working Group's <a href="https://www.w3.org/wiki/Socialwg/Social_API/Requirements">Social API Requirements</a> to understand the division of concerns.</p>
<p>Due to the diversity of viable technical approaches proposed within the Working Group, several specifications on the recommendation track provide overlapping functionality through differing mechanisms. This document exists to provide informative guidance on how and when to implement the various specifications, as well as guidance to implement bridges between recommendations with overlapping functionality.</p>
