Since the advent of the Materials Genome Initiative in the United States, a number of databases of materials and their computed properties have been developed. Many of these databases, including the Open Quantum Materials Database (OQMD), Novel Materials Discovery (NOMAD) repository, and the Materials Project, aspire to follow FAIR principles. Though they vary in scale, the types of materials contained, and the properties reported, these repositories are all alike in that they have web interfaces where users can easily search and visualize data as well as application programming interfaces (APIs) that allow programmatic access to a wide range of data and metadata -enabling individual users with knowledge of computer programming to more easily navigate large collections of materials properties and allowing these databases to be integrated into other applications.
