Finally, it defines a mechanism for reminding of upcoming events by alarm notifications.</p>
<p>The protocol enables all common transactions such as publish, schedule, reschedule, respond to scheduling requests, negotiation of changes or cancel <cite>iCalendar</cite>-based calendar components, as well as search for busy time information.

Each item representing a calendar object (event, to-do, journal entry, or other calendar components) is called a "calendar item".</p>

<p>A publish-subscribe service can advertise itself as a calendar service if it supports the functionality defined in this specification at any of its nodes. That might mean that calendar nodes are spread throughout the service and mixed with non-calendar nodes. Calendaring features are only required in the nodes that are calendar nodes.</p>
<p>The calendar service is the canonical location for calendar data and state information. Entities may submit requests to change data or download data. Entities may store calendar objects offline and attempt to synchronize at a later time. However, entities MUST be prepared for calendar data on the service to change between the time of last synchronization and when attempting an update, as calendar nodes may be shared and accessed by multiple entities.</p>

<p>A calendar node can be created through provisioning (i.e., automatically created when a user's account is provisioned), or it can be created with the publish-subscribe &lt;create/&gt; request (see section <link url='#create'>Creating Calendars</link>). It can be useful for a user to create additional calendars (e.g., soccer schedule) or for users to share a calendar (e.g., team events or conference rooms). However, note that this specification doesn&apos;t define the purpose of calendar nodes. Users may use the 'pubsub#title' and 'pubsub#description' fields in node meta-data to find out what a calendar node is for.</p>

<p>To limit the extent of the presence leak, the receiving entity SHOULD send only bare presence without the XMPP &PRIORITY;, &SHOW;, or &STATUS; element. Unfortunately, this has two implications:</p>
<ol>
<li><p>The initiating entity cannot know which of the receiving entity's resources is more likely to engage in communication. This might imply that the initiating entity will need to send a session initiation request or other communication to more than one of the receiving entity's resources (and then retract the session initiation requests that are not answered by the receiving entity). Solutions to that problem are out of scope for this specification.</p></li>
<li><p>Set up of a session might be delayed (e.g., because in Jingle it is desirable to start negotiating candidates as soon as possible but a user interface that prompts the receiving entity to explicitly approve of divulging presence will tend to delay call setup). As a result, it may be advantageous to have a way to configure unconditional decloaking in certain deployments, at least within the same trust domain.</p></li>

To keep hidden as man-in-the-middle, the attacker needs to create a respondSalt for both peers that matches its public key, the password, the challengeSalt, and the hash sum it send. The problem for the attacking client is that it had to send out a hash sum at a point where it is not possible to get the shared key (the respondSalt is missing). If the hash sum is secure against creating collisions this is not possible. The man-in-the-middle has to use brute force and create two collisions in a very short time frame.</p>

<li><strong>Farm</strong>: an XMPP client that is identified by a fully-qualified JID. The bare JID of the farm is known as the farm's countryside. Any device running a farm will have an account with an XMPP server. A countryside can host many farms (this facilitates the "clustering" of devices). In general, there exists one farm for every physical device providing computing resources to a cloud<note>Note that this is not required as in some cases, it is useful to run multiple farms on a single device. For example, two farms can have different permissions to resources.</note> The purpose of a farm is to wait for resource consumers to communicate with it in order to spawn/create and compute with virtual machines. A farm also specifies the permissions that a villein has with respect to its provided computing resources</li>
<li><strong>Virtual machine</strong>: a computing sandbox/environment that is denoted by an identifier that is internally unique to a farm. A virtual machine is spawned from a farm and can be of any "species" (i.e. computer language). A virtual machine, like a farm, exists on the resource provider's device. Example virtual machine species include JavaScript, Python, Ruby, Groovy, etc. A virtual machine is the means by which a client (known as a "villein") is able to access the computing resources of the device running the virtual machine. In short, a virtual machine is the gateway to the computing resources of the resource provider.</li>
<li><strong>Registry</strong>: an XMPP client that is identified by a fully-qualified JID. A registry maintains a list of countrysides (i.e. bare JIDs) that have active farms running on them. The purpose of a registry is to allow countryside owners to advertise themselves. A registry monitors all the presence stanzas coming out of a countryside. When there is at least one active farm on the countryside, the registry records the countryside and makes that information available upon a <tt>disco#items</tt> request.</li>
<li><strong>Villein</strong>: an XMPP client that is identified by a fully-qualified JID. A villein is a software application that is executed by a resource consumer. The purpose of a villein is to communicate with farms to spawn and compute with virtual machines. A villein communicates with virtual machines to perform some type of distributed computation by leveraging remote computing resources. "Chunks" of computation submitted to a virtual machine from a villein are known as <strong>jobs</strong>. The term "villein" comes from the medival jargon where "villeins generally rented small homes, with or without land. As part of the contract with their landlord, they were expected to use some of their time to farm the lord's fields"<note>This quote was taken from the <link url="http://en.wikipedia.org/wiki/Serfdom">surfdom</link> Wikipedia entry on 06-06-2009.</note>.</li>

<p>
In short, a resource consumer maintains a villein that communicates with a resource provider's farm in order to spawn and compute with a virtual machine that leverages the computing resources of the provider.

<section3 topic="Submitting a Job to a Virtual Machine">
<p>
A <tt>&lt;submit_job/&gt;</tt> element is wrapped by an <tt>&lt;iq/&gt;</tt> element. The purpose of <tt>&lt;submit_job/&gt;</tt> is to send code (i.e. expressions, statements, instructions) to a virtual machine for execution (i.e. evaluation, interpretation). The expression SHOULD be respective of the virtual machine's language (i.e. the virtual machine's species). If they are not, then evaluation errors SHOULD occur. The expression submitted through a <tt>&lt;submit_job/&gt;</tt> stanza can be short (e.g. set a variable value, get a variable value) or long (e.g. define a class/method, execute a long running body of statements). The submitted expression is called a <strong>job</strong> in Linked Process and is assigned a <tt>job_id</tt> as specified by the <tt>&lt;iq/&gt;</tt> <tt>id</tt> attribute value. That is, the staza id of the <tt>&lt;submit_job/&gt;</tt> is the job's id.

For example, there may be computing resources such as hardware (e.g. video cards, FPGA components) that can have specialized requirements and parameters. Moreover, particular implementations of a Linked Process farm may have specific permissions that are not general to all implementaitons (e.g. Java-specific permissions).

For example, there may be computing resources such as hardware (e.g. video cards, FPGA components) that can have specialized requirements and parameters. Moreover, particular implementations of a Linked Process farm may have specific permissions that are not general to all implementaitons (e.g. Java-specific permissions). The data forms specification provided here can be extended to support such farm specific resources.</note>.

The primary representation of a participant in a MIX channel is a proxy JID, which is an anonymized JID using the same domain as the channel and with the name of the channel encoded, using the format "&lt;generated identifier&gt;#&lt;channel&gt;@&lt;mix domain&gt;". The generated identifier MUST NOT contain the '#', '/' or '@' characters. The Channel name MAY contain the '#' character. For example in the channel 'coven@mix.shakespeare.example', the user 'hag66@shakespeare.example' might have a proxy JID of '123456#coven@mix.shakespeare.example'. The reason for the proxy JID is to support JID Hidden channels. Proxy JIDs are also used in JID Visible channels, for consistency and to enable switching of JID visibility. The "urn:xmpp:mix:nodes:jidmap" node maps from proxy JID to real JID. Servers and clients MUST determine that a JID is a proxy JID from context and MUST NOT infer that a JID is a proxy JID because it contains the '#' character.
</p>
<p>
The mapping of real bare JID to proxy JID is defined when a participant joins a channel. While a user is a participant in a Channel, the mapping between real JID and proxy JID MUST NOT be changed. This mapping must be maintained after the user leaves the channel. Proxy JID values MUST NOT be re-used. If a JID that left a channel joins the channel again the same proxy JID MAY be used again or a different new proxy JID MAY be assigned.

This specification uses examples of the style: 'hag66@shakespeare.example/UUID-a1j/7533' which are aligned to real resources, but more compact. CITATION TO BE ADDED.

The full JIDs held in the presence nodes are anonymized using a similar mechanism. First the bare JID is mapped to a bare proxy JID, using the mapping held in the "urn:xmpp:mix:nodes:jidmap" node for the bare JID. Then the resource is replaced with a generated value. For example, 'hag66@shakespeare.example/UUID-a1j/7533' in the channel coven might have a proxy JID of '123456#coven@mix.shakespeare.example/789'. There is no client visible mapping of proxy full JIDs maintained as this is not needed. The MIX channel will need to maintain a mapping, to support directly addressing clients, such as for client to client disco#info queries. While an full proxy JID is held in the presence node, the mapping to real JID MUST NOT be changed.
