class="secno">5.1 </span>Audience Targeting</span> </h3> <p> Conceptually, every Object has both a Primary and Secondary audience. The Primary audience consists of those entities directly involved or owning the object. The Secondary audience consists of the collection of entities sharing an interest in the object but who might not be directly involved (e.g."followers"). </p> <p> For instance, suppose a social network of three individuals: Bob, Joe and Jane. Bob and Joe are each friends with Jane but are not friends with one another. Bob has chosen to "follow" activities for which Jane is directly involved. Jane shares a file with Joe. </p> <p> In this example, Jane and Joe are each directly involved in the file sharing activity and together make up the Primary Audience for that event. Bob, having an interest in activities involving Jane, is the Secondary Audience. Knowing this, a system that produces or consumes the activity can intelligently notify each person of the event. </p> <p> While there are means (based on the action type, actor, object and target of the activity) to infer the primary audience for many types of activities, heuristics do not work in every case and do not provide a means of identifying the secondary audience. The <code><a href="#dfn-to" class="internalDFN" data-link-type="dfn">to</a></code>, <code><a href="#dfn-cc" class="internalDFN" data-link-type="dfn">cc</a></code>, <code><a href="#dfn-bto" class="internalDFN" data-link-type="dfn">bto</a></code> and <code><a href="#dfn-bcc" class="internalDFN" data-link-type="dfn">bcc</a></code> properties <em class="rfc2119" title="MAY">MAY</em> be used within an Object to explicitly identify the Primary and Secondary audiences. </p> <p> The prototypical use case for an Object containing these properties is the publication and redistribution of objects through an intermediary. That is, an event source generates the object and publishes it to the intermediary which determines a subset of items to display to specific individual users or groups. Such a determination can be made, in part, by identifying the Primary and Secondary Audiences for each object. </p> <p> When the event source generates the object and specifies values for the <code>to</code> and <code>cc</code> fields, the intermediary <em class="rfc2119" title="SHOULD">SHOULD</em> redistribute that object with the values of those fields intact, allowing any processor to see who the object has been targeted to. This is precisely the same model used by the <code>to</code> and <code>cc</code> fields in email systems. </p> <p> There are situations, however, in which disclosing the identity of specific members of the audience may be inappropriate. For instance, a user may not wish to let other users know that they are interested in various topics, individuals or types of events. To support this option, an implementation generating an object <em class="rfc2119" title="MAY">MAY</em> use the <code>bto</code> and <code>bcc</code> properties to list entities to whom the object should be privately targeted. When an intermediary receives an object containing these properties, it <em class="rfc2119" title="MUST">MUST</em> remove those values prior to redistributing the object. The intent is that systems <em class="rfc2119" title="MUST">MUST</em> consider entities listed within the <code>bto</code> and <code>bcc</code> properties as part of the Primary and Secondary audience but <em class="rfc2119" title="MUST NOT">MUST NOT</em> disclose that fact to any other party. </p> <p> Audience targeting information included within an Object only describes the intent of the object creator. With clear exception given to the appropriate handling of <code>bto</code> and <code>bcc</code>, this specification leaves it up to implementations to determine how the audience targeting information is used. </p> <section class="informative" id="audience-and-context" typeof="bibo:Chapter" resource="#audience-and-context" property="bibo:hasPart"> <h4 id="h-audience-and-context" resource="#h-audience-and-context"><span property="xhv:role" resource="xhv:heading"><span class="secno">5.1.1 </span>Audience and Context</span> </h4> <p><em>This section is non-normative.</em></p> <p> Activities are rarely isolated events.

It can be used, for instance, to describe that one person is a friend of another, or that one person is a member of a particular organization. The intent of modeling Relationship in this way is to allow descriptions of activities that operate on the relationships in general, and to allow representation of Collections of relationships. </p> <p> For instance, many social systems have a notion of a "friends list". These are the collection of individuals that are directly connected within a person's social graph. Suppose we have a user, Sally, with direct relationships to users Joe and Jane. Sally follows Joe's updates while Sally and Jane have a mutual relationship. </p> <p> Using the <code><a href="#dfn-relationship" class="internalDFN" data-link-type="dfn">Relationship</a></code> object, we can model these relationships as: </p> <div id="ex180-jsonld" style="display: block;"> <div class="example"> <div class="example-title marker"><span>Example 145</span></div> <pre class="highlight json hljs" aria-busy="false" aria-live="polite">{ <span class="hljs-attr">"@context"</span>: <span class="hljs-string">"https://www.w3.org/ns/activitystreams"</span>, <span class="hljs-attr">"summary"</span>: <span class="hljs-string">"Sally's friends list"</span>, <span class="hljs-attr">"type"</span>: <span class="hljs-string">"Collection"</span>, <span class="hljs-attr">"items"</span>: [ { <span class="hljs-attr">"summary"</span>: <span class="hljs-string">"Sally is influenced by Joe"</span>, <span class="hljs-attr">"type"</span>: <span class="hljs-string">"Relationship"</span>, <span class="hljs-attr">"subject"</span>: { <span class="hljs-attr">"type"</span>: <span class="hljs-string">"Person"</span>, <span class="hljs-attr">"name"</span>: <span class="hljs-string">"Sally"</span> }, <span class="hljs-attr">"relationship"</span>: <span class="hljs-string">"http://purl.org/vocab/relationship/influencedBy"</span>, <span class="hljs-attr">"object"</span>: { <span class="hljs-attr">"type"</span>: <span class="hljs-string">"Person"</span>, <span class="hljs-attr">"name"</span>: <span class="hljs-string">"Joe"</span> } }, { <span class="hljs-attr">"summary"</span>: <span class="hljs-string">"Sally is a friend of Jane"</span>, <span class="hljs-attr">"type"</span>: <span class="hljs-string">"Relationship"</span>, <span class="hljs-attr">"subject"</span>: { <span class="hljs-attr">"type"</span>: <span class="hljs-string">"Person"</span>, <span class="hljs-attr">"name"</span>: <span class="hljs-string">"Sally"</span> }, <span class="hljs-attr">"relationship"</span>: <span class="hljs-string">"http://purl.org/vocab/relationship/friendOf"</span>, <span class="hljs-attr">"object"</span>: { <span class="hljs-attr">"type"</span>: <span class="hljs-string">"Person"</span>, <span class="hljs-attr">"name"</span>: <span class="hljs-string">"Jane"</span> } } ] }</pre> </div> </div> <p> The <code><a data-lt="relationship-term" href="#dfn-relationship" class="internalDFN" data-link-type="dfn">relationship</a></code> property specifies the kind of relationship that exists between the two individuals identified by the <code><a href="#dfn-subject" class="internalDFN" data-link-type="dfn">subject</a></code> and <code><a data-lt="object-term" href="#dfn-object" class="internalDFN" data-link-type="dfn">object</a></code> properties. Used together, these three properties form what is commonly known as a " <a href="http://patterns.dataincubator.org/book/reified-statement.html">reified statement</a>" where <code><a data-lt="subject" href="#dfn-subject" class="internalDFN" data-link-type="dfn">subject</a></code> identifies the subject, <code><a data-lt="relationship-term" href="#dfn-relationship" class="internalDFN" data-link-type="dfn">relationship</a></code> identifies the predicate, and <code><a data-lt="object-term" href="#dfn-object" class="internalDFN" data-link-type="dfn">object</a></code> identifies the object. </p> <p> While use of reified statements can be problematic and confusing in certain situations, their use within the Activity Streams vocabulary to describe relationships provides a straightforward mechanism of describing changes to an individual's social graph. For instance, to indicate that Sally has created a new relationship to user Matt, an implementer can use the <code><a href="#dfn-relationship" class="internalDFN" data-link-type="dfn">Relationship</a></code> object together with the <code><a href="#dfn-create" class="internalDFN" data-link-type="dfn">Create</a></code> activity: </p> <div id="ex181-jsonldb" style="display: block;"> <div class="example"> <div class="example-title marker"><span>Example 146</span></div> <pre class="highlight json hljs" aria-busy="false" aria-live="polite">{ <span class="hljs-attr">"@context"</span>: <span class="hljs-string">"https://www.w3.org/ns/activitystreams"</span>, <span class="hljs-attr">"summary"</span>: <span class="hljs-string">"Sally became a friend of Matt"</span>, <span class="hljs-attr">"type"</span>: <span class="hljs-string">"Create"</span>, <span class="hljs-attr">"actor"</span>: <span class="hljs-string">"http://sally.example.org"</span>, <span class="hljs-attr">"object"</span>: { <span class="hljs-attr">"type"</span>: <span class="hljs-string">"Relationship"</span>, <span class="hljs-attr">"subject"</span>: <span class="hljs-string">"http://sally.example.org"</span>, <span class="hljs-attr">"relationship"</span>: <span class="hljs-string">"http://purl.org/vocab/relationship/friendOf"</span>, <span class="hljs-attr">"object"</span>: <span class="hljs-string">"http://matt.example.org"</span>, <span class="hljs-attr">"startTime"</span>: <span class="hljs-string">"2015-04-21T12:34:56"</span> } }</pre> </div> </div> <p> Additionally, modeling the relationship in this way allows implementers to articulate additional properties of the relationship itself. For instance, the date and time at which the relationship began or ended. </p> <p> Implementations may reuse existing vocabularies that have been developed for the purpose of describing relationships, or create their own guided by requirements of their particular implementation. Existing vocabularies include the " <a href="http://xmlns.com/foaf/spec/">Friend of a Friend</a>" and " <a href="http://vocab.org/relationship/">Relationship</a>" vocabularies. </p> <section class="informative" id="modeling-friend-requests" typeof="bibo:Chapter" resource="#modeling-friend-requests" property="bibo:hasPart"> <h4 id="h-modeling-friend-requests" resource="#h-modeling-friend-requests"><span property="xhv:role" resource="xhv:heading"><span class="secno">5.2.1 </span>Modeling "friend requests"</span> </h4> <p><em>This section is non-normative.</em></p> <p> One common use case for many social platforms is the establishment of symmetrical "friend" relationships, in which one user initially extends a request to another user to establish a new connection.

For example, including text such as "<code>@username</code>" within an object's content will often route the object to a special "mentions" or "inbox" stream for a particular user. Likewise, including text such as " <code>#topic</code>" within the object's content will often mark the object as being related to the topic "<code>topic</code>". Such mechanisms are commonly referred to as "mentions" and "hashtags", respectively. </p> <p> While such microsyntaxes <em class="rfc2119" title="MAY">MAY</em> be used within the values of the <code><a data-lt="content-term" href="#dfn-content" class="internalDFN" data-link-type="dfn">content</a></code>, <code><a href="#dfn-name" class="internalDFN" data-link-type="dfn">name</a></code>, and <code><a href="#dfn-summary" class="internalDFN" data-link-type="dfn">summary</a></code> properties on an Activity Streams <code><a href="#dfn-object" class="internalDFN" data-link-type="dfn">Object</a></code>, implementations <em class="rfc2119" title="SHOULD NOT">SHOULD NOT</em> be required to parse the values of those properties in order to determine the appropriate routing of notifications, categorization or linking between objects. Instead, publishers <em class="rfc2119" title="SHOULD">SHOULD</em> make appropriate use of the vocabulary terms provided specifically for these purposes. </p> <p> For example, suppose that an author wishes to send a note of thanks to another user named "@sally" with a hashtag of "#givingthanks". A typical way this message would appear within the content of a note is shown below: </p> <figure id="fig-a-simple-note-with-a-mention-an-a-hashtag"> <figcaption>Figure <span class="figno">1</span> <span class="fig-title">A simple note with a mention an a hashtag:</span></figcaption> <pre aria-busy="false" aria-live="polite" class="hljs css"> "<span class="hljs-selector-tag">Thank</span> <span class="hljs-selector-tag">you</span> @<span class="hljs-keyword">sally</span> for all your hard work! #givingthanks<span class="hljs-string">" </span></pre> </figure> <p> A typical social software implementation would typically render such a content such that "<code>@sally</code>" is replaced with a hyperlink to "@sally"'s social profile page and "<code>#givingthanks</code>" is replaced with a hyperlink to a listing of other notes that have been "tagged" with the same topic. Most implementations would also send a special notification to sally letting her know that a note mentioning her has been created. </p> <p> The following illustrates an equivalent Activity Streams <code><a href="#dfn-note" class="internalDFN" data-link-type="dfn">Note</a></code> object: </p> <div id="ex196-jsonld" style="display: block;"> <div class="example"> <div class="example-title marker"><span>Example 157</span></div> <pre class="highlight json hljs undefined" aria-busy="false" aria-live="polite">{ "@context": "https://www.w3.org/ns/activitystreams", "name": "A thank-you note", "type": "Note", "content": "Thank you <a href='http://sally.example.org'>@sally</a> for all your hard work! <a href='http://example.org/tags/givingthanks'>#givingthanks</a>", "to": { "name": "Sally", "type": "Person", "id": "http://sally.example.org" }, "tag": { "id": "http://example.org/tags/givingthanks", "name": "#givingthanks" } }</pre> </div> </div> <p> The <code>to</code> property indicates that the user "@sally" is to be considered part of the <a href="#audienceTargeting">primary audience</a> of the note and should therefore receive notification. The <code>tag</code> property associates the Note with a reference to " <code>http://example.org/tags/givingthanks</code>". Note that the <code>content</code> still includes the "<code>@sally</code>" and " <code>#givingthanks</code>" microsyntaxes but that consuming implementations are not required to parse those in order to make the appropriate associations. </p> <p> In the case a publisher wishes to indicate a mention without an associated notification, the publisher can use the <code><a href="#dfn-mention" class="internalDFN" data-link-type="dfn">Mention</a></code> object type as a value of the <code><a href="#dfn-tag" class="internalDFN" data-link-type="dfn">tag</a></code> property. </p> <div id="ex197-jsonld" style="display: block;"> <div class="example"> <div class="example-title marker"><span>Example 158</span></div> <pre class="highlight json hljs" aria-busy="false" aria-live="polite">{ <span class="hljs-attr">"@context"</span>: <span class="hljs-string">"https://www.w3.org/ns/activitystreams"</span>, <span class="hljs-attr">"name"</span>: <span class="hljs-string">"A thank-you note"</span>, <span class="hljs-attr">"type"</span>: <span class="hljs-string">"Note"</span>, <span class="hljs-attr">"content"</span>: <span class="hljs-string">"Thank you @sally for all your hard work! #givingthanks"</span>, <span class="hljs-attr">"tag"</span>: [ { <span class="hljs-attr">"type"</span>: <span class="hljs-string">"Mention"</span>, <span class="hljs-attr">"href"</span>: <span class="hljs-string">"http://example.org/people/sally"</span>, <span class="hljs-attr">"name"</span>: <span class="hljs-string">"@sally"</span> }, { <span class="hljs-attr">"id"</span>: <span class="hljs-string">"http://example.org/tags/givingthanks"</span>, <span class="hljs-attr">"name"</span>: <span class="hljs-string">"#givingthanks"</span> } ] }</pre> </div> </div> </section> <section id="origin-target" typeof="bibo:Chapter" resource="#origin-target" property="bibo:hasPart"> <h3 id="h-origin-target" resource="#h-origin-target"><span property="xhv:role" resource="xhv:heading"><span class="secno">5.7 </span>Origin and Target</span> </h3> <p> The <code><a href="#dfn-origin" class="internalDFN" data-link-type="dfn">origin</a></code> and <code><a href="#dfn-target" class="internalDFN" data-link-type="dfn">target</a></code> properties of an Activity respectively identify the entities <em>from</em> which and <em>to</em> which the action is directed.
