Abstract

OMS3 is an environmental modeling framework designed to support and ease scientific environmental models development. It is implemented in Java, programming language that makes the framework flexible and non-invasive. Java is consequently the natural language for developing OMS-compliant components. However, OMS3 ensures longevity of old models implementations providing C/C++ and Fortran bindings that allow for connecting slightly modified legacy software to fresh developed Java components.

Recently, three scientific programming languages drew the modeling community’s attention: R and Python, and NetLogo. They have a flat learning curve and the lack of declared data types makes them the flawless solution for fast scripting. Furthermore, they rely on a active developer community that keep releasing and improving open source scientific packages. This is a relevant aspect when it comes to facilitate and speed up the implementation of scientific algorithms. OMS3 functionalities have been enhanced to provide R, Python, and NetLogo bindings. As a result, multi-language modeling solutions are fully interoperable. Thanks to the framework non-invasiveness, R, Python and NetLogo scripts must only be slightly modified with source code annotations to become OMS-compliant components. The resulting components are nevertheless still executable from within the original environments. This contribution shows two actual applications of R and Python bindings: the Regional Urban Growth (RUG) implemented in R and TRansportation ANalysis SIMulation System (TRANSIMS) models which requires RTE python module.

To avoid the burden of installing required software stacks, OMS3 has been bundled into a Docker image.The enhanced flexibility in the workflow is established.
