The database component of BioModels.net is especially designed for working with annotated computational models: each model is carefully reviewed and augmented by human annotators on the BioModels.net team to add metadata linking the model elements to other biological databases and resources. The BioModels database at the European Bioinformatics Institute (EBI) system is a true database, featuring browsing, crossreferencing, searching, and facilities for visualization, exporting models in different formats, and remote application programming interface (API) access.
