The Open Molecular Software Foundation (OMSF) and the Growing Role of Open Source Software in Molecular Modeling

Area of Science:

• Computational chemistry and molecular modeling
• Scientific software development and open science principles

Background:

• Traditional molecular modeling software development is isolated, leading to duplicated effort, high costs, and limited reproducibility.
• Taxpayer-funded research is often siloed in commercial tools, reducing its public impact and accessibility.

Purpose of the Study:

• To advocate for permissively licensed open source software in molecular modeling.
• To highlight the benefits of collaborative architectures and consortia for scientific advancement.
• To introduce the Open Molecular Software Foundation (OMSF) as a supporting organization.

Main Methods:

• Promoting the adoption of open source software and permissive licensing.
• Establishing coordinated multiproject consortia (e.g., Open Force Field, Open Free Energy).
• Developing organizational structures and administrative support through entities like OMSF.

Main Results:

• Open source software acts as a scientific and economic multiplier, reducing duplicated effort and enabling validation.
• Consortia facilitate the collaborative development of shared computational infrastructure.
• OMSF provides governance and administrative support, aligning academic and industrial stakeholders.

Conclusions:

• A shift towards collaborative, open source models is essential for the molecular modeling field.
• Organizational structures like OMSF are crucial for the success and sustainability of open science initiatives.
• This framework accelerates innovation, reduces duplication, and strengthens the entire molecular modeling community.
