Presence, broadly defined as an event publish-notification infrastructure for converged applications, has emerged as a key mechanism for collecting and disseminating context attributes for next-generation services in both enterprise and provider domains. Current presence-based solutions and products lack in the ability to a) support flexible user-defined queries over dynamic presence data and b) derive composite presence from multiple provider domains. Accordingly, current uses of context are limited to individual domains/organizations and do not provide a programmable mechanism for rapid creation of context-aware services.
This work presents a large-scale presence virtualization and federation platform that (a) federates across heterogeneous presence domains and thereby enables applications to exploit cross-domain contextual data; (b) provides a programmatic interface for aggregating presence data 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.
This is a joint research project between IBM T.J. Watson Research Center and IBM Research India. The platform has undergone customer trials.
Time permitting, In the later part of the talk, I plan to cover our work in the related area of real-time social networking, and specifically talk about R-U-In? (pronounced Are you in?) - an activity-oriented social networking prototype we have developed.
