One such strategy is to build new engines by reusing as much as possible from existing components. This requires two things: firstly, the mechanisms and technologies to build a library of reusable, exten- sible and adaptable workflow components; secondly, a platform to in- tegrate those components into full applications. In this paper we show that Cumbia, being a platform for the development of workflow engines based on the modularization of workflows according to concerns, suits this task. This is illustrated with YOC, a Cumbia based implementation of YAWL.

The Context of Work

It is argued that to understand the office work context we need to go beyond tracking superficial physical attributes such as who or what is where when, and consider the state of digital resources, people’s concepts, task state, social relations and the local work culture, to name a few. In analyzing an office more deeply three concepts are especially helpful: entry points, action landscapes, and coordinating mechanisms. An entry point is a structure or cue that represents an invitation to enter an information space or office task. An activity landscape is part mental construct and part physical; it is the space users interactively construct out of the resources they find when trying to accomplish a task. A coordinating mechanism is an artifact, such as a schedule, or clock, or an environmental structure such as the layout of papers to be signed, which helps a user manage the complexity of his task. Using these three concepts we can abstract away from many of the surface attributes of work context and define the deep structure of a setting—the invariant structure that many office settings share. A long term challenge for context-aware computing is to operationalize these analytic concepts.
