1) Biomodels Database: The BioModels.net project describes itself as an international effort to: 1) define standards for model curation; 2) define vocabularies for annotating models with connections to biological data resources; and 3) provide a free, centralized, publicly accessible database of annotated computational models in Systems Biology Markup Language (SBML) and other structured formats [11] (for detail, see http:// www.ebi.ac.uk/biomodels/).
