The MREP is designed to house, manage, and allow users to run infectious disease models from an access-controlled disease MREP. The MREP contains source code of disease models that have been developed by external developers and tested in a production environment. Different versions of models used to describe various aspects of the same disease are housed in the repository. During registration, models are linked to their developers, to a paper or PubMed reference that describes the model, to the name and contact information of model creators, to the date and time of creation, and to the terms of distribution. In addition, a code, available from the versioning software described later, is used to distinguish between different model versions. The annotations captured during the model registration process also identify a model's purpose, specifications, and relevant features.
