This is especially so on parallel computers. To manage this sort of complexity, scientists are becoming increasingly interested in data abstractions. A familiar example of a data abstraction in widespread use can be found in the netCDF portable binary file library which supports an abstraction of a multi-dimensional array variable. Higher levels of abstraction can be found in the data models used in IBM's Data Explorer to visualize the many kinds of grids in current scientific use. As scientific models are becoming more complex, various abstractions, schema, and information models are being proposed to deal with the increasing amount of semantic information required to make sense of model data. For example, such things as grid representations, geometry, units, and a host of parameters and attributes, are currently being incorporated into scientific data management systems and code development environments. The purpose of this workshop is to discuss strategies for representing scientific data in ways that would support building tools for database management systems, development environments, visualization tools, and data archives. A number of computational scientists and software developers have recently presented work aimed at solving these problems and these efforts have begun to show an encouraging degree of commonality. At this workshop we would like to discuss these ideas and look for common features. It is hoped that the workshop will contribute to a community consensus on what scientific data looks like in most cases and how to represent it generically. The list of invitees includes investigators from national and government laboratories, industry, and academia. This workshop is being organized by e-mail and we welcome your participation. Please let us know at your earliest convenience if you would like to participate in the workshop and especially if you would like to present your own work in this area. Participation is limited to about 60 people because of the size our facility. If you will respond by June 30th, we will prepare a preliminary agenda to be circulated by July 11th. Please reply to either of us at the addresses below. We look forward to hearing from you.
