Our Mission
Our vision is that all biomedical knowledge and data are disseminated on the Internet using principled ontologies in such a way that the knowledge and data are semantically interoperable and useful for furthering biomedical science and clinical care.
Our mission is to create software and support services for the application of principled ontologies in biomedical science and clinical care, ranging from tools for application developers to software for end-users.
Our Team
Our team at Stanford’s Center for Biomedical Informatics Research (BMIR) has supported the BioPortal software (including its deployable option, the OntoPortal Virtual Appliance) for over 15 years. Led by Dr. Mark Musen, the development and system operations teams perform all modifications, system operations, user support, and outreach for BioPortal.
Our collaborators throughout the biomedical and semantic community participate through their software contributions, their many deployments of public and private Virtual Appliances, and their support and suggestions for our work.
