Initially focused on Brazil's Paraguay-Parana, China's Yangtze, and the Mississippi Basin in the US, the DSS integrates data and models from a wide variety of environmental sectors, including water balance, water quality, carbon balance, crop production, hydropower, and biodiversity. In this presentation we focus on the modeling framework aspect of this project. In our approach to these and other environmental modeling projects, we see a flexible, extensible modeling framework infrastructure for defining and running multi-step analytic simulations as critical. In this framework, we divide monolithic models into atomic components with clearly defined semantics encoded via rich metadata representation. Once models and their semantics and composition rules have been registered with the system by their authors or other experts, non-expert users may construct simulations as workflows of these atomic model components. A model composition engine enforces rules/constraints for composing model components into simulations, to avoid the creation of Frankenmodels, models that execute but produce scientifically invalid results. A common software environment and common representations of data and models are required, as well as an adapter strategy for code written in e.g., Fortran or python, that still enables efficient simulation runs, including parallelization. Since each new simulation, as a new composition of model components, requires calibration of parameters (fudge factors) to produce scientifically valid results, we are also developing an autocalibration engine. Finally, visualization is a key element of this modeling framework strategy, both to convey complex scientific data effectively, and also to enable non-expert users to make full use of the relevant features of the framework. We are developing a visualization environment with a strong data model, to enable visualizations, model results, and data all to be handled similarly.

Errors in medical delivery are associated with an alarming number of preventable, often fatal adverse events. A promising strategy for reversing these trends is to modernize and transform the health-care information exchange (HIE), that is, the mobilization of health-care information electronically across organizations within a region or community. The current HIE is inefficient and error-prone; it is largely paper-based, fragmented, and therefore overly complex, often relying on antiquated IT (information technology). To address these weaknesses, projects are underway to build regional and national HIEs which provide interoperable access to a variety of data sources, by a variety of stakeholders, for a variety of purposes. In this paper we present a technologist's guide to health-care interoperability. We define the stakeholders, roles, and activities that comprise an HIE solution; we describe a spectrum of interoperability approaches and point out their advantages and disadvantages; and we look in some detail at a set of real-world scenarios, discussing the interoperability approaches that best address the needs. These examples are drawn from IBM experience with real-world HIE engagements.
