The BMI Builder helps developers build a Basic Model Interface for their model by generating template source code which is then customized by the user for their particular model. Users provide some basic metadata for their model (such as names of input and output items, units, etc.) to the bmi builder which then creates creates BMI implementation files in their language of choice. The user then go through these file of files and implements the labeled sections.
The bmi_tester package provides command-line utilities for testing a Python classes that implement the Basic Model Interface (BMI). bmi_tester also provides a Python interface to the tester that allows users to run tests programmatically. The package is also easily extendable so that new tests can be added to the suite.
Standard Names Registry
A Python library for working with CSDMS Standard Names.
The CSDMS Standard Names provide a comprehensive set of naming rules and patterns that are not specific to any particular modeling domain. They were also designed to have many other nice features such as parsability and natural alphabetical grouping. CSDMS Standard Names always consist of an object part and a quantity/attribute part and the quantity part may also have an operation prefix which can consist of multiple operations.
standard_names is a Python package to define, query, operate, and manipulate CSDMS Standard Names. It is distributed with a comprehensive list of the currently defined Standard Names.
The standard_names package consists of two basic classes:
- StandardName: a single name
- NamesRegistry: a collection of names.
The standard_names package has a complete set of unit tests that are continually tested on Mac, Linux, and Windows. It is distributed both as source code and as Anaconda packages from Anaconda Cloud.

The CSDMS Web Modeling Tool, WMT, is a web application that provides an Ajax client-side graphical interface and a RESTful server-side database and API that allows users, from a web browser on a desktop, laptop or tablet computer, to build and run standalone or coupled Earth surface dynamics models on a supercomputer.
With WMT, users can:
- Design a model from a set of CSDMS components
- Edit model parameters
- Save models to a web-accessible server
- Share saved models with the community
- Submit model runs to an HPC system
- Download simulation results
For more information on WMT, including links to its documentation and its source code repositories, please see the CSDMS Web Modeling Tool wiki page.
PyMT is an Open Source Python package, developed by the Community Surface Dynamics Modeling System, that provides the necessary tools used for the coupling of models that expose the Basic Modeling Interface (BMI). It contains:
- Tools necessary for coupling models of disparate time and space scales (including grid mappers)
- Time-steppers that coordinate the sequencing of coupled models
- Exchange of data between BMI-enabled models
- Wrappers that automatically load BMI-enabled models into the PyMT framework
- Utilities that support open-source interfaces (UGRID, SGRID, CSDMS Standard Names, etc.)
- A collection of community-submitted models, written in a variety of programming languages, from a variety of process domains - but all usable from within the Python programming language
- A plug-in framework for adding additional BMI-enabled models to the framework
Dakota is a software toolkit developed at Sandia National Laboratories that provides an interface between models and a library of analysis methods, including support for sensitivity analysis, uncertainty quantification, optimization, and calibration techniques. Dakota is a powerful tool, but its learning curve is steep: the user not only must understand the structure and syntax of the Dakota input file, but also must develop intermediate code that allows Dakota to set up and run a model, read outputs from the model, and calculate a response statistic from the outputs.
The CSDMS Dakota Interface, or Dakotathon, is a Python package that wraps and extends Dakota’s file-based user interface. It simplifies the process of configuring and running a Dakota experiment, and it allows a Dakota experiment to be scripted. Dakotathon creates the Dakota input file and provides a generic analysis driver. Any model componentized in the CSDMS modeling framework automatically works with Dakotathon. Dakotathon has a plugin architecture, so models not wrapped into the CSDMS modeling framework can be accessed by Dakotathon by programmatically extending a template; an example is provided in the Dakotathon distribution.
