“…RFC 4660, Functional Description of Event Notification Filtering (S): [RFC4660] defines a mechanism that allows a watcher to include filters in its subscription. These filters limit the cases in which notifications are sent.…”

The IETF has produced many specifications related to Presence and Instant Messaging with the Session Initiation Protocol (SIP). Collectively, these specifications are known as SIP for Instant Messaging and Presence Leveraging Extensions (SIMPLE). This document serves as a guide to the SIMPLE suite of specifications. It categorizes the specifications, explains what each is for, and how they relate to each other. Status of This Memo This document is not an Internet Standards Track specification; it is published for informational purposes. This document is a product of the Internet Engineering Task Force (IETF). It represents the consensus of the IETF community. It has received public review and has been approved for publication by the Internet Engineering Steering Group (IESG). Not all documents approved by the IESG are a candidate for any level of Internet Standard; see Section 2 of RFC 5741.

“…Furthermore, the presence service typically decides what portion of the available context information to forward to watchers (e.g., the decision may be based on privacy settings). The application server could tell the presence service that it is interested in "activity" only by supplying a filter at subscription time [20]. However, this filter is optional and does not support the specification of urgency, cost, rate, required accuracy etc.…”

“…An IETF draft defining the format for event notification filtering [19] aims to develop an XML-based language to describe presence subscription queries sent by a watcher (a functional description is presented in [20]). The language includes descriptions of filtering rules (which specify what to include/exclude in the presence document) and trigger rules (which specify when to send a notification).…”

“…group subscription mechanisms (such as the use of resource-lists [5]) are considered. Subscription logic allows a limited set of XPATH query based "filter" operators [16] (e.g., alerts only on specified changes in the location value) to implement simple rules for filtered notification.…”

Presence, broadly defined as an event publish-notification infrastructure based on unified communication protocols such as SIP or XMPP, is a key enabler for rich, contextual communication and collaboration. This paper presents the design, implementation and experimental evaluation of Pressentials -a large-scale presence federation and virtualization middleware for enabling context-aware applications. This middleware provides a programmatic interface for aggregating presence from various sources and for composing base presence information into abstract, functionally richer entities for enabling applications. An underlying design consideration is to leverage capabilities of protocols that are being widely deployed today. We present scaling algorithms used within the platform to re-use data and computation commonalities across multiple applications. To highlight the flexibility of the proposed framework, we discuss use-case scenarios (across multiple domains) built using this platform.
