Sharing models as social objects through HydroShare
Abstract
Many hydrologists devote a significant amount of time to applying computational models. Sharing the results of these efforts broadly would benefit the community because scientists could, when appropriate, verify, extend, and refine existing models created by others rather than creating new models from scratch. While recent attention has been devoted to sharing hydrologic data including model outputs, approaches for sharing model instances, that is the input data required to execute a model, have received less attention. To address this need, we present functionality within HydroShare that allows scientists to share both model instances and the model programs used to execute the instances. HydroShare is an NSF-funded online system with the goal of making it simple to share data and models. The approach we designed is general and applicable to any hydrology model. It includes an extensible metadata framework capable of capturing detailed metadata for specific hydrology models, while also providing general metadata applicable to any hydrology model. Another advantage of this work is that defining a structured resource type with formal metadata fosters interoperability between cyberinfrastructure systems. This is illustrated through software providing interoperability between HydroShare and a third-party application called SWATShare that is focused on providing online visualization, execution, and management of SWAT models.
