RHESSys ecohydrology workflows (

RHESSysWorkflows provides a series of Python scripts for performing RHESSys data preparation workflows. These scripts build on the workflow system defined by EcohydroLib.

Ecohydrology library of transformation routines (

EcohydroLib provides a series of Python scripts for performing ecohydrology data preparation workflows. Workflow sub-components are orchestrated via a metadata persistence store provided by the ecohydrolib.metadata package. These scripts are built on top of a series of task-oriented APIs defined in the Python package EcohydroLib. The workflow scripts provide tools for downloading and manipulating geospatial data needed to run a ecohydrology models, information such as: digital elevation model (DEM), soils, land cover, and vegetation leaf area index. These data can be drawn both from national spatial data infrastructure (NLCD, SSURGO) as well as custom local datasets.

Mediawiki and iRODS extensions

The MediaWiki server is accessible at and the associated “RodsWiki” extension is available at

Engineering File Format Registry

Drexel maintains the Format Registry at which provides a centralized location for metadata about engineering file formats as well as sample files. In addition to preservation attributes, this also captures metadata about the representational strength of each format. The source code for this is available online at
