Model Resources
Model Resources are model-related resource types within HydroShare including Model Program, Model Instance, Model Component, Model Framework, Linked Model Configuration, Model Workflow, Model Script, and Model Module.
Model Program is the executable file containing the model’s logic (model engine).
Model Instance is the input (required) and output (optional) data for a model run for a specific time and place.
Model Component is a specific process that can be coupled with other Model Components to create a Linked Model Interface.
Linked Model Configuration is a linked set of coupled Model Components.
Model Framework is used to execute Linked Model Configurations.
Metadata framework for the hydrologic model concepts consists of new metadata terms in addition to the core ones defined by the Dublin Core Metadata Initiative (DCMI). The metadata elements become more complicated as we move from general resource types (Model Instance) to more specific resource types (SWAT Model Instance).
Objectives • Develop a core metadata framework for sharing water
models. • Implement this metadata framework in the HydroShare
online collaboration environment.
Vision • Sharing water models and associated datasets with the
broader scientific community. • Combine the HydroShare Model Resources with external
systems like SWATShare tailored for running SWAT simulations online, but lacks the sharing capabilities of HydroShare.
• Dublin Core Metadata Initiative. (2012). Dublin core metadata element set, version 1.1. • Morsy, M.M., J.L. Goodall, C. Bandaragoda, A.M. Castronova, J. Greenberg (2014).Metadata for describing
